When someone says only their way works for everyone that can show where they're coming from.
A couple people getting better from herbs , does not mean it's a cure for everyone. There are plenty of people on here who have had scattering happen from herbs and it goes years back on Curezone.
Also I agree whether drugs or herbs, they should be used cautiously but there are studies backing up safety of parasite drugs with controlled use. (there is potential for side effects whether drugs or herbs).
Dr. Simon Yu, a Holistic doctor uses parasite medications because he says he finds they are more effective than the herbs.
"Albendazole proved very effective and safe in the treatment of single and multiple helminth infections in children under 2 years of age, achieving cure rates of 100% in both Ascaris lumbricoides and Necator americanus respectively, 83% in Trichuris trichiura and 66% in Hymenolepis nana."
