Hey i wanted to chime in.I saw Dr.Galland as im sure you know his name,he writes many articles/books on parasites/leaky gut/etc.Anyway his treatment for giardia is alinia and albenza combo along with saccramyces boulardii.I hope this helps....
Im doing a parasite cleanse now as i do not feel comfortable taking antibiotics right now thanks to that awful drug flagyl!I know have candida and god knows what else...its terrible.
