My previous experience with the utilization of ascorbic acid in the treatment of viral diseases led me to hypothesize that ascorbate would be of value in the treatment of AIDS (acquired immune deficiency syndrome). Preliminary clinical evidence is that massive doses of ascorbate (50-200 grams per 24 hours) can suppress the symptoms of the disease and can markedly reduce the tendency for secondary infections. In combination with usual treatments for the secondary infections, large doses of ascorbate will often produce a clinical remission which shows every evidence of being prolonged if treatment is continued. This clinical remission is achieved despite continuing laboratory evidence of helper T-cell suppression. There may be a complete or partial destruction of the helper T-cells during an initial infection that does not necessitate a continuing toxicity from some source to maintain a permanent or prolonged helper T-cell suppression. However, it is possible ascorbate may prevent that destruction if used adequately during that prodrome period. Emphasis is put upon the recognition and treatment of the frequent intestinal parasites. Food and chemical sensitivities occur frequently in the AID syndrome and may aggravate symptoms considered to be part of the AID syndrome. A topical C-paste has been found very effective in the treatment of herpes simplex and, to a lesser extent, in the treatment of some Kaposi's lesions. Increasingly, clinical research on other methods of treating AIDS is being "contaminated" by patients taking ascorbate.
