I have never heard about this product , but if you goggle it , it is the first thing on the page, click on it, then scroll down to Terms, Legal & Herbal Safety Guidelines, and it gives you alot of info, it also gives 24 reviews from users.Also with any type of natural product , you have to be carefull if you are on any type of medication.I,m currently on pain pills for my back, and I used to take alot of vitamins, but now because of that I cant take most of them, esspecialy St Johns Wort.There are lots of other sites listed on the page that i,m sure will be of some use, hope that helps,Misty
