Well, ugh! I did that turmeric thing I found online by other FReepers’ recommendation, in trying to cure the recurring rash I have/had on the tops of my hands.
Bleeccch! It said to drink 1 Tbsp in a glass of water, every so many hours or several times per day. Aaacck, I can still taste it!
It was CLAY, like you would make a mud mask out of for your face! And it tasted like dirt - BAD dirt. Or burning plastic! Not only that, it didn’t work - and I endured that grossness for at least a month, I was so desperate.
I eat curry all the time - at least several times per week - and love it. So I am ingesting turmeric in small amounts, anyway, but never again with the “intense turmeric therapy”! Ptooey! *spit spit*
The Japanese eat burdock root, they call it Gobo, but you might not be able to find any fresh root for sale unless you can get to an Asian market.
In the spring and summer you can dig all you want. There are few places where it doesn't grow. Most of it will be tough though unless you find young plants in rich soil. But it is commonly sold as an herbal tincture in "progressive" stores that sell a lot of such "supplements."
Hope it works on your rash, if you try it.
