A few years ago I had written a post on the P Forum with my experience when I had parasites go into my eyes. It was a very painful experience. I know that many people are dealing with pain in their lives and I thought that I'd make a post on this. Painful inflammation can be controlled with using herbs to break a vicious cycle.
One comment that I want to make is that many people will use herbs (or drugs) to kill parasites, but what many don't know is that when there is die-off there can be a danger in some instances with swelling, inflammation, and pain. This would be true for brain parasites, as a good example.
Anti-inflammatory meds are usually given out to combat these problems by using steroids -- cortisone, prednisone, and the likes.
