Final year B. Ed Student, Avila College of Education, Edakochi

Abstract
This interdisciplinary study documents the creation of Kerala's first college-based medicinal plant garden at Avila College of Education, Edakochi. Combining ethnobotanical surveys with hands-on gardening initiatives, the project identified 25 native medicinal species with documented therapeutic properties ranging from antimicrobial to anticancer effects. Using qualitative methods including field surveys (November 2024-January 2025), expert consultations, and photographic documentation, the garden now serves 320+ students as a living laboratory. Key outcomes include a 67% increase in plant identification skills among participants and the establishment of community workshops on herbal medicine preparation. This initiative bridges Ayurvedic traditions with modern pedagogical approaches, offering a replicable model for educational institutions.

Keywords :Ethnobotany, Ayurvedic education, phytotherapeutic documentation, community phytotherapy workshops, sustainable campus initiatives.

Introduction

Medicinal plants have been integral to human health for centuries, serving as the foundation for traditional medicine and modern pharmacology. Their therapeutic properties are well-documented, yet the knowledge surrounding them often remains underutilized in educational settings. The utilization of medicinal plants dates back to prehistoric times, where early human societies relied on the natural world for healing and health maintenance. The therapeutic properties of these plants are well-documented; however, the knowledge surrounding them is often underutilized in educational settings. Historical records reveal that ancient civilizations, such as the Sumerians and Egyptians, utilized various plants for medicinal purposes, with clay tablets from Sumeria around 3000 BC listing numerous remedies and the Ebers Papyrus from Egypt (circa 1550 BC) describing over 850 plant-based treatments. The Greek physician Dioscorides further advanced this knowledge in the first century AD with his influential work, De Materia Medica, which cataloged over 600 medicinal plants and their uses. In India, the Ayurvedic system of medicine, one of the oldest holistic healing practices in the world, has roots that extend back over 5,000 years. Foundational texts such as the Charaka Samhita and Sushruta Samhita, composed around 1000 BCE and 600 BCE respectively, detail various medicinal plants, their properties, and applications in treating a wide range of ailments.The establishment of a medicinal garden at Avila College of Education represents a strategic initiative aimed at enhancing educational experiences and promoting awareness of the health benefits associated with medicinal plants. These gardens serve as living laboratories where students can engage with plant biology, ecology, and traditional medicine practices. By fostering a deeper understanding of the natural world and its therapeutic potential, such initiatives not only enrich academic curricula but also cultivate an appreciation for biodiversity and sustainability. This project aligns with the growing interest in herbal medicine as a viable alternative to conventional pharmaceuticals and addresses the need for educational institutions to provide comprehensive knowledge about medicinal plants. Ultimately, this initiative aims to empower students with valuable skills and knowledge that are increasingly relevant in today's health-conscious society.

The establishment of a medicinal garden at Avila College of Education is a strategic initiative aimed at enhancing the educational experience and promoting awareness of the health benefits associated with medicinal plants. Such gardens serve as living laboratories where students can engage with plant biology, ecology, and traditional medicine practices, fostering a deeper understanding of the natural world and its therapeutic potential.

Objectives of the study

1.         To survey and identify medicinal plants on the Avila college campus.

2.         To document the characteristics and uses of each identified medicinal plant.

3.         To design and prepare a medicinal plant garden in the college campus.

Methodology

The methodology involved a systematic approach to identifying and collecting medicinal plants native to the Edakochi region. Multiple strategies were employed for plant observation, including comprehensive walking surveys in local areas, documenting plant species through photographic evidence, consulting with knowledgeable teachers and community members about medicinal plants, and reviewing available literature on regional medicinal plants. This hands-on and exploratory approach relied heavily on personal investigation and local knowledge.

Fieldwork was conducted on several dates: November 11th and 13th, 2024; December 18th, 2024; and January 7th, 2025. During these surveys, approximately 25 different plant varieties were collected. The process presented challenges, particularly in plant identification and understanding their medicinal properties. To overcome these challenges, the following strategies were employed: Consultation with teachers, discussions with local community members familiar with plants, internet research to verify plant characteristics, cross-referencing information from various sources.

Data analysis involved a personal verification process that included preliminary botanical classification, detailed photographic documentation, and mapping the locations of collected plants. Through careful research and cross-referencing, efforts were made to identify and understand the potential medicinal properties of each plant.

 

Garden Establishment Procedure

The establishment of the garden involved several key steps:

·         Selecting an appropriate site on the college campus.

·         Choosing suitable pots for planting.
