The total forest and tree cover is 79.42 million hectares, which is 24.16 percent of the total geographical area. The tribal population of India as per the 2011 census was 104 million, constituting 8.6% of the country’s population. Tribal people in India depend on forests for their livelihood. Wild foods are important Non-timber forest products for the tribes. The tribal people are very close to nature and have hereditary traditional knowledge of eating wild plants and plant parts like tubers, shoots, leaves, fruits, etc. as a source of food. Although these wild edible plants play an important role in food security, they are often overlooked. Primitive man, through trial and error, selected several wild edible plants that were edible and later domesticated. The present research paper reviews the documented wild edible plants and their use by tribes in different parts of India. Streamlining these wild edible plant species will provide food security. Less susceptible to wild food diseases can be easily grown without pesticide application. Ironically, these plants are still unknown or less known in other parts of the world. Wild edible plant species can be popularized after phytochemical analysis and nutraceutical studies. The present study on the review of wild edible plant species would help collect the variety of edible plant species used by different tribes in different parts of India.
