I suggest that you build up slowly while using turpentine. I have used 1/2 tsp. and have had severe Herx. Not fun at all but at least you know it is working.
Drinking a lot of water and making sure you have several BMs daily will help get rid of the die off.
Hang in there, I have been battling internal Morgellons symptoms for more than an year and I plan on keeping up my regimen.
