Spelling
 

Some are spelling it Turmeric and others are spelling Tumeric. Is this the same thing? That's what threw me off in op's original post, I knew Tumeric is a spice, but had never heard of Turmeric.

tumeric for my knee
 

I have been using it for about 2 years, just the spice nothing else. Before that I had had cortizone, and those expensive shots in the knee. Nothing worked so I had to wear a brace to not only exercise but just get around. I don't use much, perhaps 1/4 teaspoon.

I believe I read somewhere that Curcumin helps prevent cancer so I decided to try it. It comes in a spice called Turmeric. I used it twice a day sprinkled generously over soups and salads. I suspect I might have suffered a side effect from it because something happened that never happened before. So I stopped using it and the side effect went away after about 10 to 15 days. Now I'm using it again but with a much lighter sprinkle. The side effect did not come back.

I already eat an anti-inflammatory diet so I probably won't gain anything by using it.

Subsequent is not necessarily consequent.
Caveat Emptor!!

Tumeric is a common misspelling of the spice. It is turmeric, it's a spice, and there is no such thing as tumeric.
