I have been reading the Humaworm forum on Curezone. Very interesting. It seems like many of the reactions people are getting from it are from candida die off. Others do see some visible evidence of parasites. Some parasites may be too small to be seen though. Humaworm might be worth trying if after using grapefruit seed extract for a while and still don't feel any change. grapefruit seed extract is also anti parasitic. The laxative action of the Humaworm may also help to get rid of parasites, however it seems like it could be a very annoying side effect. If you do decide to use Humaworm, imo it makes sense to use grapefruit seed extract for a while first to get the candida level reduced greatly. While grapefruit seed extract is also anti parasitic, Humaworm might do a better job against parasites. I see the standard usage of Humaworm is for a month. I guess that is probably the maximum amount of time one would want to use those herbs considering the possibility of longer term toxicity. I noticed that it has relatively little senna or buckthorn, however I am wondering why they have been included at all.
