when is better time to take antiparasitic/anticandida?

hi everybody

this is a general one for every antiparasitic, anticandida...supplements. would it be better to take them alone before meals or with meals to enhance the effects?

my guess is that this is depending on the type of parasites, etc. but maybe some of you got good results with a strategy or another.

for example some said to take proteolitic enzymes 30' before meals and at night to help destroy them.
another said take antiparasitic before meals, others during meals.

in the local market there are products containing starch or even maltodextrine saying that these sugars attract them to eat the antiparasitic herbs in the supplements.
i am reluctant to these one but they said it has a logic.
I tried once and i had some results - eliminating someof them - but got worst because bacterial/protozoan infection.
the same with some natural treatment - for example mashed pumpkin seeds togheter with honey.

what is your opinion/experience, best approach.

I am taking them now before meals 30' minutes trying to have "kosher" ones not containing sugars of any kind. And last thing at night. Wormwood , Black-Walnut , thyme...

many thanks,
dave
