The book also has: over 20 case histories (sometimes of patients who are difficult to treat, due to poor CD4 and viral load numbers, and intolerance or apparent resistance to many antiretrovirals); outcomes comparisons of patients treated in Dr. Kaiser's program, vs. others who received mainstream HIV treatment without the natural-therapy component; information about certain major herbs from both Western and Chinese medical traditions (although Dr. Kaiser usually refers patients to herbalists experienced with HIV for specific prescriptions); a discussion of approved and experimental antiretrovirals; and an appendix explaining common laboratory tests.
