Rash

Posted by debraananda on Jul 26, 2011

Purchased at iHerb

The first 3 times I took this product I produced a really bad rash, I was very red and hot all over, the fourth was a little better, but I have not taken it since

Holy flush

Posted by Reviewer1972599 on Oct 31, 2012

Purchased at iHerb

I have never had a flush before but this was HORRIBLE. I stuck it out for about a week and then stopped. Shouldve stuck it out for longer as apparently it takes a couple of weeks to stop. I did feel quite good otherwise though.

Too much for my system

Posted by Reviewer1682534 on Jul 30, 2012

Purchased at iHerb

I took this to help reduce my high cholesterol but the hot flashes were too intense and it turned my face red in public. It also raised my blood sugar. Had to give it up.
