hi i had gone through your query and understand your concerns about present situation. homeopathic medicines are work on the fixed principle of INDIVIDUALIZATION that is patient diagnosis, no priority is given for the disease diagnosis amoebiasis,typhoid or malaria etc. allopathic medicines are based on germ theory-disease diagnosis,receptor theory. allopathic medicines are antidote or decrease the action of the homeopathic medicines if you take simultaneously or previously. yes flagyentyl definitely decrease or antidote the action of the previous homeopathic medicines are you taken for amoebiasis. but it is usually overcome by proper homeopathic similimum within short period of time. wishing you good health.
