Educational Encyclopedia

Parasite Encyclopedia

Educational reference of 67 human-infecting parasites — their symptoms, life cycles, transmission, conventional medical treatments, and traditional herbal alternatives. Grounded in the work of Hulda Clark and 10+ clinical parasitology and integrative-medicine textbooks (Garcia, Horowitz, Junger, Davis, Krohn, Tippens, Gerbehy, and more). Not a substitute for medical diagnosis.
