I didn't save any links on Colloidal Silver and Acne since I came across them mostly by browsing and reading testimonials online (you can do a google search on Colloidal Silver for Acne and see what you come up with) But I do have this pretty good article: http://www.all-natural.com/silver-1.html
Also, I bought my colliodal silver maker at www.sunstoneherbals.com and they also have some good information. As another benefit, I haven't been sick since I started taking CS, so it isn't just for acne.
By trichnella parasites I was refering to Dr Hulda Clark 's book " The Cure For All Diseases " were she says that Acne is caused by the trichnella parasite. If you want more info on zapping search on curezone, I've only zapped 4 or 5 times so I don't have alot of info on the subject.
Finally- by sulfur based treatments I just meant over the counter creams with sulfur in them (not benzoyl peroxide). I just found that these work better for me, I'm sorry I can't remember the name of the product I used since its been awhile but you can find it at the drugstore. Look for the "adult acne" label or sulfur in the product; again everyone is different and this only helped after I did several months of B5 and Liver Flushes so it really wasn't the #1 thing that cured my acne, it just helped clear up my small zits faster.
Good luck with clearing your acne I hope you find something that finally works..
