Herbal Acne pills

Has anyone used these before? Specifically Bell Product #60 found in Health Food stores? They come in bottles of 90 capsules that should be taken 6/day (2 pills/3 x day). I am trying to research if the ingredients will affect my blood sugar. The lady at the store wasn't certain.

Ingredients include: Oregon grape root extract, bitter sweet extract, sarsaparilla, juniper berries, neem extract.

If anyone could help me search for more info online that would be wonderful. I have had acne since puberty, and I've been on accutane twice (teens), and several OTC,and expensive spa products. I notice a slight improvement, but I am still getting break outs, at 34 years old. Thanks everyone!
