On the Morgellons group on FB it was used for many many years. The members used it all the time. I've used it a couple times years ago. When it does kill off parasites you can end up with recirculating heavy metals as parasites use those as protection, and it can cause herx if don't take the right amount and are constipated. They advised to take something natural to make sure your bowels are moving at least twice a day. I took too much once and for about two weeks after that I had water on my knee. It was to where I couldn't walk and very painful. I'd never had water on my knee before so I knew it was from die off, herx and heavy metals redistributing into joints. So you need to get the doses right and make sure you're not constipated.
