Hello, my son is 23 and has acne only on his forehead and back. He has been on antibiotics that helps sporactically. I have read that liver flushes help this, since nothing else seems to help. I have read that the herbal parasite cleanse can be obtained here. I would like to know first if you feel this is good for his problem, and if it interferes with any drugs or medicines (he is taking propecia and bactrim F). If so, I would like to order this. We live outside the US but he will be in the US in 2 weeks and can pick it up at an address there. Thank you, please respond soon! S.
