Turmeric has been used for hundreds of years in South Asia, for a variety of ailments, and is also a staple spice that many use.
It has a vast array of benefits, and there has been a lot of research, and still more research being done about its countless benefits.
I recommend buying the actual turmeric, it looks like ginger part of the same family, many health/organic groceries and middle eastern groceries should carry it, and also purchasing the spice grounded up they sell it at every store.
I add it to everything when I’m cooking chicken or a dish i chop some up and add it, it also gives it a nice color, but be-careful with touching it too much, it has a strong color! you can also add the dried spice to dishes.
