cs will help the symptoms, but will not address the problem. only fasting and Liver Flushing
cleansing will cure the problem. check out the barefoot herbalist and other appropriate forums that i mentioned.
the key with topical silver is it only works when it is wet. hopefully you are making your own so it is cheap. then get an amber or cobalt glass sprayer/mister and spray it on your face as often as you want. properly made cs can be taken in large amounts in any orifice with a great degree of safety and limited side effects. the key is CORRECTLY MADE which requires you to educate yourself and make it yourself. everything else is a risk, although there are some commercially available products which i would use topically in a pinch or internally in a DIRE emergency. i believe steve555 has a handle on that. i have no experience with otc cs.
