Tinctures

I'd like to take tinctures but everytime I take them I feel drunk, the Candida reacts to them. Mainly I'd like to take these tinctures just in case I have parasites (although I have a feeling its just candida thats the problem) I think they might have a positive effect but its somewhat negated by the candida feeding off them. The question is, should I take them (I've got Echinacea, Black-Walnut hull, Wormwood , licorice and goldenseal) or should the current herbs/meds I use be enough to do the job they do anyway - Grape fruit seed extract, pure coconut oil, oregano oil, garlic, onions, Yeast Raiders (Holland and Barrett)? Any advice appreciated. Chris
