Traditional Medicine Practices in Tribal Communities of Wayanad, Kerala: Ethnobotanical Insights and Conservation Challenges for Endangered Species
Abstract
Traditional medicine remains a cornerstone of primary healthcare among tribal communities in India, particularly within ecologically sensitive regions such as the Wayanad district of Kerala. The present study documents and analyzes the use of endangered plant species and mud-based remedies in the traditional healthcare practices of Wayanad’sindigenous populations. Ethnobotanical surveys, conducted through structured interviews with tribal healers, revealed that multiple threatened species—including medicinal orchids, tree barks, and forest herbs—are integral to treatments for ailments such as respiratory disorders, digestive problems, wounds, and skin infections. Additionally, unique mud-based therapeutic applications were recorded, reflecting deep ecological knowledge and cultural adaptation to the local environment. Findings indicate that over 35% of the documented plant species are currently categorized as vulnerable or endangered under the IUCN Red List, raising concerns over both biodiversity conservation and the continuity of indigenous medical systems. The study highlights that unsustainable harvesting, habitat loss, and limited transmission of traditional knowledge across generations threaten this intricate healthcare tradition. Integrating community-led conservation, sustainable resource management, and policy support is vital to safeguard both the ecological resources and the cultural heritage of these communities.
This research underscores the dual urgency of conserving endangered medicinal plants and recognizing traditional healing systems as invaluable reservoirs of knowledge. Protecting these practices not only preserves biodiversity but also contributes to sustainable healthcare solutions in the face of global health and environmental challenges.

Introduction
Traditional medicine remains one of the most enduring links between biodiversity and cultural heritage inhuman societies. Globally, the World Health Organization (WHO) estimates that nearly 80% of the world’spopulation relies on traditional medicine for primary health care. This reliance is particularly strong among indigenous and tribal communities, where ethnomedicinal knowledge forms the foundation of health systems, linking natural resources with well-being and cultural identity.
In India, the role of traditional medicine is profound, with systems such as Ayurveda, Siddha, and Unani coexisting alongside rich tribal ethnomedicinal traditions. Kerala, often known as the “cradle of Ayurveda,” also harbors numerous indigenous communities that practice traditional healing using locally available resources. Within Kerala, the Wayanad district occupies a unique ecological and cultural niche. Positioned in the Western Ghats, a global biodiversity hotspot, Wayanad is home to diverse tribal groups, including the Paniya, Kurichiya, Kuruma, and Kattunaikka communities. These groups possess deep-rooted knowledge of forest ecosystems, plants, soils, and healing practices that have been passed down through generations. The ethnomedicinal practices of Wayanad’stribes rely not only on medicinal plants but also on natural resources such as sacred muds and soils used in wound healing, detoxification, and ritual purification. Such practices underscore the multidimensional relationship between people and their environment, integrating ecological, spiritual, and therapeutic dimensions. However, the survival of this knowledge is increasingly threatened by habitat degradation, overexploitation, modernization, and declining intergenerational transfer of traditional wisdom.
A pressing concern is the dependence on endangered plant species. Several species that form the backbone of tribal medicine are categorized as rare, vulnerable, or endangered under the IUCN Red List and India’s Wildlife Protection Act. Examples include Gloriosa superba (used for anti-inflammatory and rheumatism treatment), Rauvolfia serpentina (for hypertension and snakebites), and Coscinium fenestratum (antimicrobial and antidiabetic). Unsustainable harvesting, coupled with deforestation and commercial exploitation, threatens the very resources upon which these medical systems depend. Documenting and analyzing this knowledge is crucial for three reasons: 1. Cultural preservation – safeguarding intangible heritage and tribal identity. 2. Conservation strategy – highlighting species at risk and promoting sustainable harvesting. 3. Scientific validation – bridging ethnomedicine with pharmacological research for novel drug discovery. TABLE 1 SELECTED ENDANGERED MEDICINAL PLANT SPECIES USED BY TRIBES IN WAYANAD IUCN / National Botanical Name Local Name Traditional Uses Status Anti-inflammatory, arthritis, snakebite Gloriosa superba Kalihari Vulnerable antidote Coscinium fenestratum Maramanjal Antimicrobial, antidiabetic, wound healing Endangered Rauvolfia serpentina Sarpagandha Hypertension, snakebite, mental disorders Endangered Raktha Pterocarpus santalinus Skin ailments, blood purification Endangered Chandan Nothapodytes Amruta Cancer therapy (camptothecin alkaloid) Vulnerable nimmoniana These examples illustrate how endangered species form a vital component of traditional medicine while simultaneously being at risk from ecological and anthropogenic pressures.
Another distinctive feature of Wayanad’stribal medicine is the use of medicinal muds and soils. Certain clays and soils, often sourced from sacred groves or riverbanks, are applied in treating skin diseases, detoxification therapies, or bone fractures. This aligns with global practices such as geophagy and therapeutic clay use observed in Africa, South America, and Asia, reflecting a shared human heritage of earth-based healing.
The tribal communities of Wayanad embody a living library of ethnomedicinal wisdom, linking endangered plant species and natural resources with holistic healing. Yet, this knowledge is fragile, situated at the intersection of biodiversity conservation, cultural survival, and modern scientific inquiry. A systematic study of these practices not only safeguards indigenous heritage but also contributes to sustainable healthcare and biodiversity management at both local and global scales. This paper seeks to document and analyze the endangered ethnomedicinal resources of Wayanad’stribal communities, with a focus on plant species and mud therapies, while exploring their implications for conservation, healthcare, and global sustainability.
Conclusion
This study highlights the enduring significance of traditional medicine in the tribal communities of Wayanad, Kerala, where biodiversity, culture, and healthcare intersect. The findings demonstrate that indigenous groups such as the Kurichiya, Paniya, and Kattunaikka continue to rely on plant-based and mud therapies to meet primary healthcare needs, particularly for musculoskeletal, dermatological, and systemic disorders. However, the documentation also reveals that several of the species most valued for their medicinal properties, including Gloriosa superba, Pterocarpus santalinus, and Rauvolfia serpentina, fall within endangered or vulnerable categories. This dual reality underscores both the resilience of indigenous healthcare systems and the fragility of their ecological foundations.
The integration of mud-based therapies, a relatively underexplored dimension of ethnomedicine, reflects the innovative ways in which local communities engage with their environment. Such practices not only hold cultural significance but also present opportunities for interdisciplinary scientific exploration, bridging ethnobotany, soil science, and pharmacology. Yet, the sustainability of this knowledge system is at risk. Intergenerational transmission is declining, driven by cultural change, modernization, and limited recognition of indigenous healers. Without active documentation, conservation, and integration into healthcare and policy frameworks, both biological resources and intangible cultural heritage may be lost. Importantly, our rich legacy of traditional knowledge on medicinal plants, bio-resources, and their applications deserves protection and recognition through patent filings. Such measures safeguard indigenous intellectual property while promoting cultural heritage on a global platform. Equally vital is ensuring that tribal communities with expertise in traditional healing are eligible for government incentives and support, comparable to those offered for commercial crops and products. These initiatives would encourage preservation, innovation, and sustainable promotion of traditional knowledge systems.
Globally, these findings resonate with broader concerns in ethnomedicine and biodiversity conservation, aligning with international conventions such as the CBD and the Nagoya Protocol, which advocate protection of indigenous knowledge and equitable benefit-sharing.
Ultimately, the preservation of traditional medicine in Wayanad is vital not only for tribal health security but also for safeguarding biocultural diversity. Protecting these practices contributes to ecological balance, supports local livelihoods, and enriches global scientific understanding—ensuring that indigenous wisdom continues to inspire sustainable healthcare solutions for generations to come.
