I wouldnt be taking wormwood unless your postive you have parasites. Herbs used for parasites can be pretty harsh on the GI tract. I would get tested before you start to take herbs for parasites. Oil of oregano can be pretty harsh on the gut as well. It can burn the the intestinal lining causing inflammation and mucus production. Coconut oil is more gentle on the Gi tract. Undecenoic acid is a good aproach as well.
Die-off is not always productive as it can cause too much inflammation and toxins to be released. Dr. jeff made a good point about this in his most recent posting.
For some berries(problems with fructose) and seeds(mucus production) might add to their candida problem.
