why turmeric is used for most of health issues ?

can anyone gimme reason behind the why turmeric used for most of the human health problems 

Turmeric is receiving a lot of praise at the moment for helping good health and joint pain. It’s available as capsules and powder. I did read somewhere the basic powder you can buy in supermarkets the better option …just popping a spoon full in stir fries and stews etc.
I do try to have some but personally not keen on the taste at all really …don’t think it’s a cancer cure though !!
