I may not come from Asia, I'm an African but one thing we don't joke about as an afircan is the indigenous or local medicines.
Alot of africans maybe in time past don't like the industrial medicines like my grandpa will call them 'white chalk' so they came up with this ayurvedic medicine which consist of turmeric,garlic,ginger, and all.
Whether its the modern industrial medicine or traditional medicine that works better, what i know is that it has to be people's choice and whatever they believed in.
It is important to note that some vegetables and fruits are also good for the body which could also prevent diseases. So while shopping for they ayurvedic, you can also shop for these veggies and fruits and thats why most times all these are sold together by the same seller.
