Importance of Ethnobotany in Indian context | Botany Optional for UPSC PDF Download

Introduction

Ethnobotany is a field of study that combines "ethno," referring to the examination of plant culture, and "botany," which is the study of plant species. It is a scientific discipline that investigates the connections between plants and human societies. Dr. J. W. Harshberger first introduced the term "Ethnobotany" during a lecture in 1895, defining it as the study of how primitive and indigenous people use plants, particularly for purposes like food and clothing.
Ethnobotany is a branch of science that explores the knowledge and customs of people concerning the various uses of plants, including their medicinal and spiritual roles. Throughout history, humans have relied on different plants for their daily needs. Ethnobotany, although relatively new, focuses on the fundamental principles governing the relationships between humans and plant life. In essence, it encompasses all aspects of plants' significance in the world, along with other species that inhabit the Earth.
Plants play a vital role in benefiting humanity by providing food, shelter, clean air, and medicines. They also offer a wide range of edible and aromatic components, including roots, tubers, vines, fruits, and leaves that can be sourced from forests and other environments.

Historical Background

• The term "Ethnobotany" was first coined by J. W. Harshberger in 1895. The roots of Ethnomedicinal science can be traced back to ancient India. This scientific discipline has its origins in India and is supported by ancient Indian scriptures such as the Rigveda, Atharvaveda, and religious texts, which provide valuable information about Ethnomedicinal plants.
• In the two Vedic periods, Rigveda and Atharvaveda, there is a list of 148 medicinal plants. Charak Vedic literature lists around 400-450 medicinal plants. In more recent times, the book "Indian Medicinal Plants" by Kartika and Basu (1935) included 1,775 plants, while "A Glossary of Indian Medicinal Plants" by Chopra and others covered more than 3,500 medicinal plants. Therefore, our contemporary knowledge of Indian pharmacology includes nearly 3,500 species of plants, both indigenous and exotic. The first book on Indian Ethnobotany, "A Glimpse of Indian Ethnobotany" by Jain (1981), marked an important milestone in this field.
• Even from the archaeological remains of Mohenjo-Daro and Harappa, evidence of the use of herbal medicine has been found. The roots of all sciences in India can be traced back to the Vedas. The Atharvaveda, in particular, contains references to herbal medicine. Subsequently, the Rigveda and Ayurveda provide detailed scientific descriptions of plants. Ayurveda is considered the foundation of Indian traditional medicine.
• In the 19th century, several significant works related to medicinal plants were published. Sir William Jones authored "Botanical Observations on Select Plants," John Fleming compiled a "Catalog of Medicinal Plants," Against wrote "Materia Medica of Hindustan," Roxburgh contributed "Flora Indica," Dr. Dimak published "Materia Medica of Western India," Carrying authored "Farmacopeea India," and Dr. Mohiuddin Sarif wrote a "Supplement to the Farmacopeea of India." In 1895, Sir Joyerg Wott, a Britisher, authored "Dictionary of Economic Products of India." Subsequently, works like "Endemic Medicine of India" by Kaneyala Dave and "Indigenous Drugs of India" by R.N. Chopra added to the knowledge base.
• Throughout history, humans have relied on nature for their basic needs, leading to an early fascination with the diverse plant life around them. Initially, humans sought plants for sustenance, shelter, and protection, gradually discovering their therapeutic properties. This marked the beginning of the science of medicine. The Rigveda mentions how humans learned to differentiate between edible and toxic plants by observing animals.
• Evidence from the oldest civilizations, including those in Africa, China, Egypt, and the Indus Valley, suggests the use of herbal medicine in these regions. The earliest records of medicinal plants in the Indian subcontinent can be found in the Rigveda and Ayurveda, with this work spanning from 4500 BC to 1600 BC. Ayurveda and the Charak Vedic literature date back to 900 BC, while Sushruta Vedic literature, focused on surgery, medical treatment, and medicines, dates back to 500 BC. These systems later influenced Greek medicine, which was adopted by the Arabs and subsequently spread to India and Europe.
• In India, references to the therapeutic properties of 99 plants can be traced back to the Vedic period, dating from 3500 to 1800 BC. The Atharva Veda provides a more detailed account of 288 medicinal plants. "Vruksha Ayurveda," attributed to Parasar, is one of the oldest texts on this subject. The Rig Veda (1400-1800 BC) and Atharva Veda (4500-2500 BC) are the sacred texts that laid the foundation for the science of life and the art of Hindu culture. These texts emphasize the significance of medicinal plants.
• Around 377 AD, a Greek physician expressed the famous idea: "Let your cure be your food, and eat your medicine." Dioscorides, a Greek physician, compiled "De Materia Medica," a catalog of approximately 600 plant species found in the Mediterranean. It also contains information on how the Greeks used plants, particularly for medicinal purposes. In many countries, the existing traditional knowledge systems were shaped by the use of plants for healing.
• Cultural healers in various parts of the world have long recognized the interconnectedness of the body, mind, soul, and overall well-being. This holistic approach to health has set new standards for treating various diseases. Until the mid-19th century, plants were the primary therapeutic agents used by humans, and their role in medicine remains relevant today. In the mid-19th century, the population of the Indian subcontinent was severely affected by the bacteria responsible for Hansen's disease, also known as leprosy.
• In the late 19th century, ethnobotany emerged as a scientific discipline, providing a new tool for pharmaceutical research. Public institutions, such as the World Health Organization, and private pharmaceutical companies initiated ethnobotanical expeditions. The utilization of historical documents is of utmost importance in gaining insights into the relationships between people and their environment in the past. Discovering or recovering information from manuscripts, books, or other sources contributes to the understanding of the evolution of plant usage, including concepts related to illness and cultural practices.

Indo-India Subcontinent

• The knowledge of the healing properties and effects of plants, minerals, and other substances dates back to ancient times when people migrated to the Indian subcontinent. Evidence suggests that medical practices such as dentistry and trepanation were in use as early as 7000 BCE in this region. Ongoing archaeological excavations have revealed indications of the use of medicinal plants in the central Gangetic region since the 2nd millennium BCE, and many of these plants are still utilized in Ayurvedic traditional medicine.
• India is a land characterized by a diverse population, each with its own unique religious beliefs, culture, language, and dialects. Within this diverse landscape, various systems of traditional medicine have developed. Some of these healing systems were introduced from outside the region and became enriched in India over time. Throughout history, Indian society has relied on traditional medicinal practices. However, during the British colonial era, the introduction of allopathic medicine and the disregard for Indian traditional medicine by British rulers led to a significant decline in the practice of traditional medicine.
• Despite the rapid scientific advancements in allopathic medicine and the availability of modern medical facilities, approximately 70% of India's rural population continues to rely on traditional medicine for their primary healthcare needs.

British Rule (1755-1947)

• The 18th century witnessed significant contributions to the study of medicinal plants in India, laying a strong foundation for later research endeavors. Among these contributions, the works of Ainslie in 1813 and O'Shaughnessy and Wallich in 1844 stand out as particularly noteworthy. As the 18th century came to a close, Indian research in the field of medicinal plants produced two major works: one in Hindu medicine and the other in indigenous medicine.
• The earliest references to medicinal plants in India can be traced back to the use of Soma by the Indo-Aryans. However, the accurate identification of this plant in contemporary terms remains a subject of debate and speculation. The plant is mentioned in historical texts by its common names, and around twenty different plant species have been associated with the name Soma, ranging from the Sarco stemma seed plant to the genus mushaira plant. Some experts today believe it may refer to a woody plant called pachyclade.
• The science of ethnobotany began to take shape during the British colonial rule. Researchers studied both wild and cultivated plants as part of their studies in floristic biology. Roxburgh, in particular, conducted extensive floristic investigations in South India, documenting not only the botanical aspects of herbs but also their traditional uses and local names.
• From 1873, Sir George Watt focused on economically significant plant species, particularly in the state of India. He compiled the "Dictionary of the Economic Products of India" (1889-1896) and "The Commercial Products of India." In the former dictionary, Watt provided nearly 3,000 local names of plant products along with their uses, as collected from various regions of India. He also cross-referenced these names with important Indian languages and dialects. His work paid special attention to sacred plants and played a pivotal role in shaping the field of ethnobotany and indigenous knowledge of Indian society. Later, Bodding documented the medicines used by Santal tribes and other useful plants, publishing these findings in the Memoirs of the Asiatic Society of Bengal.
• These efforts to catalog, document, and illustrate plants with notes on their medicinal uses in the 19th century contributed significantly to Watt's six-volume "Dictionary of the Economic Products," published between 1889 and 1896. India has a rich socio-cultural history and heritage, and indigenous knowledge about the medicinal uses of native plants was preserved by local communities throughout the country.

Era after independence of Pakistan

• In Pakistan, approximately 6,000 plant species have been identified and documented, with more than 600 of these species recognized for their medicinal properties. Pakistan's flora is exceptionally diverse, owing to its varied climate, soil conditions, and multiple ecological regions spread across a vast area. The use of plants has a long history in Pakistan.
• In the early 1950s, over 80% of Pakistan's population relied entirely on ethnomedicine for their traditional healthcare practices. Ancient Unani medicine, which encompasses the use of medicinal plants along with animals and minerals, holds a significant place in Pakistan's cultural heritage. 
• Pakistan is among the countries where the traditional Unani medicine system is deeply ingrained in a large portion of the population. The Unani medical system, which originated in Greece and was further developed and enriched by Muslim scholars, has a substantial presence in Muslim civilization. In the Indo-Pak subcontinent, Muslim scholars embraced the Unani medical system and propagated it for many generations.

Era after independence of India

• India possesses an extensive wealth of ethnobotanical knowledge, thanks to its rich cultural diversity, ancient connections, and diverse flora comprising approximately 20,000 angiosperm species. Ethnobotanical studies conducted as part of coordinated research in India have revealed that Indian tribes utilize over 9,500 wild plant species to fulfill various needs. These plants serve diverse purposes, including 7,500 for medicinal uses, 3,900 for food, 525 for cordage and fiber, 400 for fodder, around 300 as pesticides, 300 for gums, resins, and dyes, 100 for incense and perfumes, and 700 for cultural and various other requirements.
• Ethnobotanical research in India was initiated by Jain and his associates, who conducted studies among the tribes of Central India, particularly in Madhya Pradesh. These studies involved collecting ethnobotanical information and voucher plant species while conducting interviews with various tribal communities to gather knowledge about ethnobotany.
• Other researchers like Grosi and Shahzad studied the medicinal plants used by the people of Dhirkot, identifying 43 medicinal plant species from 16 families used individually or in combinations by local residents. Ravindran et al. conducted an ethnobotanical survey and reported 11 plant species used for various disorders in Pichavaram mangrove forest, Tamil Nadu, India. Chhetri et al. reported 281 species from 108 different families used in folk medicine in Darjeeling Himalaya, with a caveat that 15% of the medicinal plants in the region were under vulnerable conditions. Sajem and Gosai conducted research on the medicinal plant usage by the Jantia tribe in India, identifying 39 medicinal plant species from 27 different families. These plants were used to treat various disorders. Bhosale et al. surveyed the use of medicinal plants by tribal communities in the Purandhar region of Maharashtra, reporting 77 plant species belonging to 30 families used for treating conditions like cough, asthma, diabetes, diphtheria, snake bites, and scorpion stings. Jain et al. documented plant usage in the Sariska and Siliserh region of Alwar district, Rajasthan, India, identifying 110 plant species used for various diseases.
  • (A) Ayurveda: Ayurveda is an ancient and comprehensive medicinal system native to India, combining the Sanskrit words "Ayur" (life) and "Veda" (knowledge). It finds its roots in the Vedas, the oldest Indian literature dating back to 5000-1000 BC, which contain information about natural remedies. Ayurveda encompasses various clinical subdivisions, including Kayacikitsa (internal medicine), Shalya Tantra (surgery), Salakya (diseases of the head and neck), Kaumarabhrtya (pediatric medicine, OB and Gynaecology), Bhuta Vidya (psychiatry), Agada Tantra (toxicology), Rasayana Tantra (rejuvenation and geriatrics), and Vajikarana (aphrodisiacs and eugenics).
  • (B) Siddha: The Siddha system of medicine, originating from Tamil culture in southern India, has its roots in the Indus Valley civilization. Influenced by Chinese alchemy, Taoism, and Taoist geophysics, it is believed to have been developed by 18 siddhars, a class of Tamil sages. Siddha medicine, while sharing similarities with Ayurveda, has its own philosophy, holistic approach, and lifestyle-based measures.
  • (C) Unani: The Unani system of medicine is a blend of ancient medicinal systems from Egypt, Syria, Iran, China, India, and several other Eastern countries. It originated in Greece and evolved in Arabia. Arab and Persian settlers introduced Unani medicine to India in the 11th century, where it gained recognition and further development during the Mughal rule.
  • (D) Amchi: Amchi or Sowa-Rigpa is an ancient medicinal system documented in India, Mongolia, Nepal, Bhutan, the Himalayan region of India, parts of China, and former Russia. While there is debate about its origin, with some attributing it to India, Tibet, or China, Amchi shares similarities with Ayurveda and has also been influenced by Chinese traditional medicine and Tibetan content.
  • (E) Folk Medicine: Apart from the documented traditional medicine systems, uncodified folk medicine plays a crucial role in maintaining health and treating illnesses among rural indigenous communities in India. This knowledge, passed down orally through generations, involves the use of nearly 8,000 plant species and the formulation of about 25,000 plant-based remedies.

 Scope of Ethnobotany

• Ethnobotanical studies encompass a wide range of areas and offer valuable insights into the relationship between humans and plants. The scope of ethnobotany is multifaceted and includes various aspects such as conservation, nutrition, support for livelihoods, rural healthcare, drug use and abuse, cultural practices, cottage industries, and the preservation of ecosystems and energy resources.
• One important aspect of ethnobotanical research is its contribution to plant conservation efforts. This includes identifying the conservation status of plants, such as whether they are vulnerable, critically endangered, invasive weeds, or rare species. By understanding how these plants are used by local communities, conservation strategies can be developed to protect them.
• Ethnobotany also plays a crucial role in addressing contemporary and future challenges. It helps in the exploration of nutrition, the identification of life-supporting plant species, rural healthcare practices, drug usage patterns, social customs, cottage industries, and the sustainable management of natural resources and energy.
• One recent approach in ethnobotanical research is to examine the relationship between humans and plants from the perspective of plant populations. This includes studying selective exploitation, reproductive biology, species competition, and factors influencing the survival of plant species.
• According to Schulter (1962), ethnobotany can be defined as "The study of the relationship that exists between people of primitive societies and their plant environment." In simpler terms, it represents an anthropological approach to botany. Ethnobotanical research has gained significant attention in recent decades and has established connections with various specialized fields such as ethnomedicine, ethnopharmacology, ethnoagriculture, ethnoveterinary medicine, and ethnopharmacology.
• Ethnobotanical studies have contributed to the search for new medicinal compounds, the discovery of valuable germplasm, the development of new food and fodder sources, and tools for economic development. They also play a crucial role in the conservation of natural resources and cultural heritage.
• Many scientists and scholars from diverse backgrounds, including botanists, phytochemists, pharmacologists, anthropologists, and traditional medicine practitioners, are actively engaged in advancing the field of ethnobotany. Ethnomedicine is a recent branch of medicine where valuable knowledge about specific plants and their uses in treating various ailments is gathered from local communities. This knowledge is clinically evaluated, and the therapeutic properties of these plants are studied through various medicinal aspects.
• Plants are integral to fulfilling the three basic human needs: food, clothing, and shelter. They provide essential resources such as food, fiber, oils, beverages, tannins, dyes, gums, resins, and condiments. In India, for example, no social or religious function is considered complete without offerings of flowers. People often seek peace and solace in natural environments surrounded by greenery, emphasizing the aesthetic and psychological importance of plants.
• The study of ethnobotany has also presented opportunities for understanding and effectively managing plant incompatibility reactions in a fascinating way.

Ethnobotany- Science or Art?

• The question of whether ethnobotany is a science or an art is a natural one and is occasionally raised. To address this question, we must first clarify the definitions of science and art. Art involves practical application or doing, while science is concerned with knowledge and understanding. Ethnobotany can be viewed as a science when it involves gathering knowledge about the principles governing the natural world and applying that knowledge for the benefit of society.
• It may seem surprising that one field can encompass both science and art, but in the case of ethnobotany, this is indeed true. When ethnobotany involves the use of plants for ornamentation, aesthetic pleasure, unique garden designs, cosmetics, woodworking in crafting toys and other wooden articles, it can be considered an art. This aspect of ethnobotany is closely related to various branches such as Ethnomusicology, Ethnohorticulture, Ethnolinguistics, Ethnometricology, Ethnoecology, Ethnocosmetics, and more.
• On the other hand, ethnobotany is recognized as a science when it involves the utilization of plants for medicinal purposes and the study of their chemical components for healing various diseases. This scientific aspect of ethnobotany is connected to branches such as Ethnopharmacy, Ethnopharmacology, Ethnophytochemistry, Ethnomedicine, and others.
• In essence, ethnobotany bridges the gap between science and art, as it encompasses both the understanding of nature's principles and the practical application of that knowledge for various human purposes.

Approach to Ethnobotany

The approaches outlined above can lead to the development of various subtypes within the field of ethnobotany, each specializing in different aspects of the relationship between humans and plants:

• Ethnobryology: The ethnobotanical study of bryophytes.
• Ethnocosmetics: Materials used by various cultural groups, folk, or indigenous communities for body care, grooming, or decoration, particularly for skin and hair.
• Ethnodietetics: This branch of ethnogastrology focuses on the selection, content, frequency, consumption, and nutritional value of food.
• Ethnoecology: Concerned with indigenous beliefs, concepts, knowledge, and practices related to the interaction between humans and their natural environment, including conservation strategies for species, communities, and ecosystems.
• Ethnogastrology: Encompasses all aspects of food and beverage consumption, including the type, source, frequency, quantity, and preparation of materials used by various cultural groups, folk, or indigenous communities to satisfy hunger and thirst. This also covers emergency, famine, or subsistence foods.
• Ethnogynecology: Focuses on indigenous beliefs, knowledge, ideas, and practices related to the treatment of female fertility issues, family planning, pregnancy, childbirth, and related matters.
• Ethnohorticulture: Addresses indigenous beliefs, concepts, knowledge, and practices within a community, folk, or indigenous group related to the cultivation of plants for fruits, vegetables, ornaments, and aesthetic purposes.
• Ethnomedicine: Involves indigenous beliefs, concepts, knowledge, and practices within a community, folk, or indigenous group for the prevention, alleviation, or expression of illness, pain, and folk medicine.
• Ethnomedical Botany: The study of plants used as medicine within any ethnic group, folk, or race, focusing on ethnobotanical aspects of medicinal sources.
• Ethnomusicology: Examines all aspects of vocal and instrumental music within a community, including the origin, evolution, themes, and materials associated with their music.
• Ethnonarcotics: The study of narcotic substances within any ethnic group, folk, or race.
• Ethnoophthalmology: Focuses on indigenous beliefs, knowledge, ideas, and practices for treating eye ailments, injuries, or vision impairments.
• Ethnoorthopedics: Addresses indigenous beliefs, knowledge, ideas, and practices related to the healing of bones.
• Ethnopediatrics: Explores indigenous knowledge, ideas, and practices concerning the care of children during illness, colic complaints, and pain.
• Ethnopaleobotany: Examines ethnobotanical aspects of fossilized plant material.
• Ethnopharmacy: Involves indigenous beliefs, concepts, knowledge, ideas, and practices within any ethnic group, folk, or race regarding the collection, preparation, preservation, and dispensing of medicines.
• Ethnopharmacology: Focuses on the pharmacological study of biological materials associated with an ethnic group, including indigenous methods of observation and experimentation on medicinal substances.
• Ethnotoxicology: The study of substances considered or used as harmful, non-toxic intoxicants within any ethnic group, folk, or race.
• Ethnoveterinary: Explores indigenous beliefs, knowledge, ideas, skills, and practices related to animal health among different cultures.
• Ethnobiology: Encompasses all aspects of the direct relationship between humans and animals.

The Indigenous Culture of Indian country

• According to anthropologists, India has seen the migration of six different racial groups from outside its borders, including the Negrito, the original Australoid, the Mongoloids, the Mediterranean, the Western Brachycephals, and the Nordic. The indigenous people of India are commonly referred to as tribes. India is home to over 573 indigenous communities, comprising more than 53 million tribes from 227 ethnic groups. These indigenous communities make up nearly 20% of the country's population. 
• They are distributed across 5,000 villages in India, primarily in the central and eastern regions, as well as in the northeast. There are also scattered pockets of indigenous communities in the northwestern and northwestern plains, the northern regions, and the Andaman and Nicobar Islands in the extreme south. Many of these indigenous tribes are facing the threat of extinction, and the Indian constitution provides special protections for them.
• Ethnobotanists aim to investigate how these indigenous communities use plants for various purposes, including food, clothing, shelter, fodder, fuel, and furniture, as well as how they utilize plants for medicinal purposes based on the unique characteristics of plant species. Ethnobotanists employ scientific methods to gather and understand the valuable knowledge of these plants.
• Various ethnobotanical indices are used to analyze the use of plants in different regions and among various tribes or communities. Researchers categorize and perform mathematical analysis to study the knowledge systems, uses, and methods of transmission across different regions. Cultural significance indexes are employed in this analysis.

Crop Plant Genetic Resources command by the Tribal of Indian country

• India is the place of origin for many crop plants, while others have adapted and thrived in the diverse agro-ecological regions where indigenous communities reside. Some notable examples include rice in the northeastern region of India, millets, leafy vegetables, temperate fruits, and pseudo-cereals in the Himalayas. In many regions, crops have become an integral part of the local ethnic culture.
• Over time, various cultural uses of these crops have contributed to the generation of a wide range of landraces managed by tribal communities. Different ethnic tribes have been cultivating their preferred landraces in these regions. Tribal selection has played a significant role in shaping the direction of crop diversity by utilizing local variability. Tribal selection, along with factors like soil conditions, cultural practices, and plant lineage, has contributed significantly to local crop improvement and the development of regionally adapted varieties.
• With improved means of communication and cross-cultural contacts, there has been an exchange of crop diversity among different ethnic groups, leading to the accumulation and spread of diversity. The improvement of crop diversity among tribals and traditional farming communities has also occurred through the exchange of seeds in local markets, which often serves as a repository of crop variability with a wide range of skills.

Role of Ethnobotany in the conservation of plants

• Ethnobotanical studies provide insights into the cultures of local communities and their knowledge of various useful plant species. This indigenous knowledge is a valuable ecological resource, particularly in understanding the traditional uses of plants for medicinal and spiritual purposes. However, this local knowledge is often at risk of being lost due to modernization processes. Deforestation, population growth, and other environmental challenges are rapidly leading to the loss of biodiversity and the destruction of natural ecosystems. Therefore, the preservation of vast tropical forests and other natural systems is essential to conserve the potential benefits of diverse plant resources, including food, medicine, and materials.
• It is crucial to empower local indigenous peoples to take the lead in conserving their own culture. This involves identifying and documenting vulnerable plant species and promoting their thoughtful use. This is a dynamic and ever-evolving process, with new knowledge constantly being acquired and connected to traditional practices. Emphasizing the economic benefits of sustainable forest product use over traditional timber products can help protect the leaves, roots, stems, fruits, and seeds that offer these valuable benefits and improve the well-being of people. Non-timber forest products serve as a safeguard against a country's challenging economic conditions.

Traditional apply for Biodiversity Use and Conservation

• Tribals in North East Central and arid regions of India practice shifting cultivation. In this method, a forested area is cleared for cultivation, and the plant biomass is burned, with the ashes containing essential nutrients being returned to the field. After a year of cultivation, the land is left fallow for several years, allowing it to naturally regain fertility, while the cultivator moves to a new plot of land. Notably, unlike modern cultivation, the tribals do not clear-cut the entire forest but selectively retain species like jackfruit, mango, mahua, and myrobalans, enriching the ecosystem with native species.
• The way indigenous communities manipulate heterogeneity for the integrity of their ecosystem and for their own social purposes is fascinating. Under a shifting agriculture cycle of around sixty years, the number of crop species is diverse, with an emphasis on cereals at lower elevations due to the efficiency of nutrient use, while tuber crops are grown at higher elevations where soil fertility levels are lower. In shorter cycles of two to five years, there is a shift towards tuber crops. 
• In settled agricultural systems, high heterogeneity is maintained through crop rotation in both space and time, with mixed and mono cropping systems coexisting. For example, during the monsoon season, paddy is grown alongside maize, millets, and pseudo-millets like amaranths, while pulses such as black beans, golden gram, peas, and soybeans are also cultivated. All of these crops are native cultivars. In the winter season, both traditional and wheat are cultivated, along with barley.

For Nature Conservation: A part of the Culture of indigenous Societies of Indian country

• Indigenous tribes in India follow animism and naturalism as integral parts of their cultural beliefs and practices. They consider plants, animals, trees, rivers, ponds, lakes, stones, and mountains as sacred entities, and their beliefs emphasize the need for protection. These communal beliefs have resulted in the preservation of numerous untouched forests, known as 'sacred groves,' dedicated to gods or mother goddesses. These groves date back thousands of years and reflect a time when Indian society was in a primitive hunting and gathering stage.
• The level of preservation in these sacred forests varies, with some untouched to the extent that even dry foliage, branches, and fallen fruits and seeds remain undisturbed. These groves likely contribute to forest soil fertility and regeneration. The sacred groves of the past have evolved into modern India's "Biosphere Reserves." For example, the Attappady Valley in Kerala, inhabited by around 30,000 tribes, is now part of the Nilgiri Biosphere Reserve. The region's biodiversity is closely tied to the indigenous knowledge of these tribes.
• Many tribal societies revere specific trees that have been preserved for generations. For instance, the Mundas and Santhals worship mahua and kadamba trees, the Bhauiyas and Gonds regard dhak as sacred, and the tribes of Rajasthan hold the khejri tree in reverence. These cultural practices have contributed to the conservation of these tree species.

Ethnomedicinal Knowledge of Street Herbal Vendors

• Street herbal vendors, known as 'shilajitwala,' are descendants of indigenous communities hailing from Madhya Pradesh, Gujarat, Rajasthan, and Maharashtra, in India. These vendors are predominantly illiterate but have gained practical knowledge from traditional schools of medicine within India. Their expertise in medicinal herbs has been acquired over time through trial and error, passed down through generations. These vendors carry a range of raw medicinal herbs and travel from one city to another, selling their herbal remedies door to door, often displaying these crude herbs in glass jars along roadsides.
• Their inventory includes several essential crude medicinal plants and plant parts, such as Asparagus racemosus, Withania somnifera, Tinospora Cordifolia, Tribulus terrestris, Curculigo orchioides, palas, Orchis latifolia, ginger, Embelia ribes, ironwood, Helicteres isora, and the three myrobalans.
• In addition to herbal remedies, these vendors also offer chemical preparations, with 'shilajit,' also known as 'stone gum,' being a prominent product among them.
  • (A) Shilajit: Shilajit is obtained from rocks in the Himalayan region during the hot summer months. It is found in association with plants like Euphorbia royleana, white clover, common evening primrose, mosses, and short grasses. Shilajit comes in four types: Gold (Red), Silver (White), Copper (Blue), and Iron (Blackish brown). Shilajit's analysis reveals organic and mineral components, including fulvic acid, hippuric acid, silica, iron, alumina, magnesium, potassium, sodium, phosphorus, lime, manganese, zinc, and molybdenum. It also contains amino acids and synthetic metalloenzymes, as well as fatty acids, gums, and collagen. Shilajit is believed to have medicinal properties and is used to treat various conditions, including venereal diseases, gastrointestinal disorders, respiratory diseases, gallstones, jaundice, and sexual impotence. It is particularly valued as an aphrodisiac tonic. Raw shilajit is typically 'purified' by heating it with myrobalans and 'cow urine' before use.
  • (B) Samudra Phena: This is a white carbonate shell obtained from the cuttlefish Sepia officinalis. It is hard, brittle, porous, and has a smooth surface. It is widely used as a remedy.
  • (C) Lauha Bhasma: Lauha Bhasma is prepared by calcining iron along with extracts from three myrobalans, milk, and cow's water. It is used in the treatment of anemia.
  • (D) Makardhwaja Buti: This is an inorganic preparation made from Red mercury compound (Hg) with a small amount of gold (Au). It is commonly used with other herbal products and is considered a valuable tonic that may enhance longevity.

Significance of Ethnobotany

• The significance of ethnobotany becomes apparent in the context of the modern world, characterized by a growing population and rapid technological advancements, leading to an increasingly urbanized lifestyle. This urbanization, coupled with factors like industrialization, uncontrolled urban expansion, intensive agriculture, deforestation, and overgrazing, has disrupted the delicate ecological balance and led to environmental deterioration.
• As society modernizes and urbanizes, the ancestral knowledge, customs, and beliefs regarding plant uses are gradually eroding. The traditional wisdom related to plant utilization is under threat, and there is a risk that this invaluable knowledge may disappear forever.
• The decline in cultural diversity and the erosion of traditional knowledge about how to use, distribute, and extract plants and their components are pressing concerns. To address this, ethnobotanical studies have emerged as a vital tool for conserving this endangered knowledge. Ethnobotanical research involves comprehensive investigations into the inventory, usage, and conservation of plants, particularly those with cultural, spiritual, or sacred significance, both within and outside indigenous communities.
• Ethnobotanical studies help identify plants and their specific parts used for treating various diseases, preserving this traditional wisdom. Additionally, these studies introduce new plant species to the scientific community, opening doors for potential research and development opportunities.
• Furthermore, ethnobotanical research allows for comparative studies of plant usage among different communities, highlighting the intercultural and intracultural variations in plant knowledge, which can vary with age, social class, and other factors. This research documents how plants and plant parts are used, consumed, the methods of consumption, dosage, and routes of administration for treating various ailments by traditional healers and Vaidyas (traditional practitioners) in villages.
• In summary, ethnobotany plays a crucial role in documenting, preserving, and understanding the rich plant knowledge held by indigenous cultures and traditional communities, ensuring that this heritage is not lost as societies modernize and urbanize.

Conclusion

• Around the world, various cultures are known for their ethnobotanical practices, rooted in historical traditions. Ethnobotany encompasses a wide scope, involving the collection of diverse plants that hold medicinal and religious significance. These plants are used in treating a range of diseases and are integral to indigenous knowledge systems and rituals. Indigenous communities have deep connections with these plants, relying on them for their daily needs and beliefs.
• Ethnobotany has paved the way for the study of ethnomedicine, focusing on the medicinal properties of these valuable plant species. Ethnobotanists and indigenous people alike have become increasingly interested in exploring the potential of these plants. Indigenous healers and traditional healthcare practitioners worldwide have accumulated extensive knowledge about these medicinal plants, tailored to specific diseases within their communities.
• Some ethnobotanists are dedicated to understanding the uses of these plants by conducting surveys, using questionnaires and interviews to gather indigenous knowledge from tribal and local communities. It is crucial to document and preserve this indigenous knowledge held by these communities before it vanishes. Since this traditional knowledge is often passed down orally from one generation to the next, it is imperative to systematically document, identify, and collect data related to the uses and benefits of these plants, following proper formats and guidance.
