Lots of research says that certain medications kill off certain parasites. For example triclabendazole could target certain fluke type parasites that other meds may not be able to as effectively.
Where is the research on herbs? If you have them it'd be great to see. I respect the herbal way of cleansing but it doesn't seem to help everyone on here. Medicines have their place to.
Many people seem to report scattering of parasites feom taking herbs so it may actually not be a good idea for everyone. If it works for you great but some medications are meant to beat out parasites! Also some medicine parasite protocols call for repeated treatments or taking them for a few days at a time so it isn't just a temporary one shot for people following a parasite drug protocol.
