Yep MSM human grade powder mixed in water in the morning as good quality as you can get along with vitamin C is a really good protocol for getting the skin well so it will be great for your eczema as well. Build up from one teaspoon to more as you can. MSM makes the skin slippery and is sulphur so that the paras can't stick as well. Dr. Hulda Clark says - " I have seen that eczema is due to roundworms".
Yes and a good diet is paramount I think (mine was never). The drugs will give you a good head start... but don't rely on them too much.
Zapping, herbs, also works too if you are diligent. My biggest mistake was to think I was cured......... I had a major relapse and never knew I had huge ones still inside....
