Funny thing about kratom is that it is banned in Indonesia where it is natural vegetation. Farmers have been chewing its leaves for decades for energy and pain management.
Its taste is close to a catpoop rolled up in dogshit. It also doesn't mix very well in liquid. So taking it has its challenges. But its properties (energy, pain, relaxation) are quite unique. Big Pharma is working hard on banning it because who needs competition? It also can cause constipation, but that can be a desired effect for some...
