>There are many references to it in Ayurveda - the Indian/Hindu medical sciences. Ayurveda believes in using food as medicine to non only prevent a large majority of human diseases, but also to cure several of them — all with almost zero side effects.

Homeopathy also has zero side effects (apart from having zero effects). There is no medical wisdom in any of the old texts (from any culture) that are relevant in 2018. The vast majority is pseudo-scientific nonsense that should be rejected.

>Turmeric is just one such extremely powerful & healthy food item that Western science seems to be playing catch up on. Many others like black pepper, honey, asafoetida (hing), coconut oil, copper utensils, cloves, cardamom, mustard seeds, neem (gold), milk, clarified butter (ghee).

All of those are known to the entire world, both their exaggerated benefits and their limitations. Sorry to burst your bubble.

>But the other aspect is that we are slowly losing all that because Indians try to mimic the West in almost everything they do &

You are severely confused. Do you take coconut oil when you get cancer? Or do you take Turmeric? If you get liver disease do you use copper vessels? Nobody cares where the idea originated. When it comes to their health, people will go where there are results.

> nowadays do not trust our own sciences like Ayurveda etc, even at the risk of debilitating side effects.

That doesn't explain the success of pseudo-scientific products marketed under the "Patanjali" brand.

Also, there is no such thing as "Western science". Its a global science and people from around the world are contributing to it. Go into any research lab in the "west". You'll find a large portion of people there belonging to chinese and south asian heritage apart from the local ethnic majority.
