The tribal people have generally developed a deep understanding and knowledge on the medicinal herbal plants that surrounds them. Also the importance of these plants to the indigenous people medicinally, spiritually, even culturally have been mentioned and stated in their folklore. The traditional or folk knowledge of using the medicinal herb plants in healing various sickness and diseases have been passed down from generation to generation, from the earliest days till modern day. There are sacred groves that the indigenous tribes have reserved or set aside in the forests. They could be large or small areas. These sacred groves have played an important role in the socio-cutural and religious society of these tribes as a way of preservation and protection of these medicinal herbal plants. The traditional knowledge serves as the best foundation for effective in situ conservation, which calls for precise and current data on the status of medicinal plant populations, the extent and type of local communities' plant use, and the resource base's ability to support various economic activities. The focus on this paper will be on how oral tradition played a significant role in passing down the knowledge of traditional healing to the younger generation and also how to use the herbs for its medicinal purpose. The Khasi people's usage of medicinal herbal plants goes far beyond simple medical care; it is also closely linked to their cultural identity and spiritual beliefs.
