Studies show some of the chemicals in coal tar may cause cancer, but only in very high concentrations, such as in what is used in industrial paving. Anyone using tar regularly should follow a regular skin cancer checkup schedule. California requires OTC coal tar shampoos, lotions and creams that contain more than percent coal tar to be labeled with cancer warnings. However, the FDA maintains that OTC products with coal tar concentrations between percent and 5 percent are safe and effective for psoriasis, and there is no scientific evidence that the tar in OTC products is carcinogenic.
I have ordered items from all day chemist from India and have never been disappointed. Although i have not bought acyclovir before from them, they do sell two generic types of acyclovir for 2 dollars for 5 grams. The only problem is shipping is 25 dollars and will take between 15-21 days. I just read that the 1000 dollar a pill hepatitis drug in US will cost 10 dollars for generic version in india. Read reviews for all day chemists, i think they have good reviews. I am thinking about buying some myself because abreva is not working. Good Luck
