Rated 5 out of 5 by Fresh Herbs! I purchased this recently and received a $5 coupon for my next order (yay!). Also, I noticed my bottle was manufactured last month, which means the herbs are especially fresh and potent.

I will be purchasing many more supplements from this company in the future. July 10, 2012
