I don't have much to report in response to your questions but am glad to hear you are looking forward to getting on to your herbs as soon as they arrive.
One thing I did find helpful in parasite detox (in between herbs) is eating raw garlic. Usually at night, put a clove straight into the mouth - chew with mouth closed and swallow.
Eating cloves yes, oregano oil, grapefruit seed extract as well are all anti parasitic. But the big ones for hitting them hard are the Black-Walnut hulls, and Wormwood which need to be taken together with cloves to kill the eggies.
I had this big awful worm which was in me for months, and now its gone, so there is hope for u (if a worm is what you have). Do not dispair. These herbs REALLY work.
