Query: great product

After taking it for a month, I noticed the rash I had on my both uper arm disappeared. It tast great with food like rice tomato and granola. The only reason gave it 4 stars is that the eczema on the back of my hand keep coming back. I guess it will take a little while. Anyway, great stuff, highly recommend it.
