So, ethnobotanists spend their time with these tribes to learn about herbal plants. Especially the people in tropical forests. Now a days, there is serious threat to these wild species of extinction. The commercialization is leading to deforestation and the ultimate result will be extinction. The governments should pay attention to these serious issues.
