Medicinal Garden

Medicinal garden is a natural repository of medicinal plants which signifies a rich heritage of traditional knowledge and plant diversity. A medicinal plant contains substances that can be used for therapeutic purposes. The objective of establishing a Medicinal garden at Thanal is for the purpose of education to expose our students to common and rare medicinal plant species with comprehensive knowledge of identification and research. Botanical gardens and medicinal plant gardens are also actively involved in the conservation of the plants as well as traditional knowledge.

India is endowed with plants of medicinal importance and is blessed with 25% of the world’s biodiversity. More than 7000 species of plants found in various ecosystems are said to be used for medicine in our country. Climate change is one of the most severe threats to biodiversity as well as ecosystem functioning. Plants are extremely sensitive to climate changes and do not acclimatize randomly. The need of the hour is to have a focused research approach to preserve them through various conservation strategies.
