I think the 'herb' you are concerned about is actually homeopathic silica (not a herb) it is great for helping expel foreign objects from your body. I stood on a sea urchin and the spines broke off in my foot - they were very deeply imbedded - but after taking the silica pillules for a few weeks all the spines miraculously came out. I would be very wary about using it if I had any type of clips etc in my body. Can't make any comment about the effect of OP though, which I have tried for the first time a couple of hours ago (1tsp VCO). I was thinking though that some of these really bad side effects might come about if you were to inadvertently swallow a bit of the oil you are swishing about in your mouth - I don't think that would be too good for you after 10 mins of swishing!
