Yes! My daughter had Hashimoto's cured when her parasites were gone. Our Naturopath muscle tested her and found this to work. I also had Grave's Disease 5 years ago and it was reversed with a Chinese herbal supplement, but I am sure an an autoimmune disease it was initially brought on through the parasites. What else would severely compromise the immune system and endocrine system? I don't drink much, or smoke or take any kind of drugs so I'm finding my major health improvements from the cleansing. Hope this helps,
