I've struggled with taking herbs due to a reactive stomach. I have the same issue with antibiotics, however have tolerated them well when taken with an enteric coating. Recently I've experimented with dropping Oregano oil and grapefruit seed extract into an empty enteric capsule. The results have been really good at treating a joint fungal and bacterial overgrowth in my small intestine. I'm now wondering if this is actually safe. The usual method of taking oil/tinctures is just to drop into a glass of water and drink. However in the EC, the oil is more concentrated and comes directly in contact with the lining of the intestine. Anyone tried this or have any thoughts?
