There is a very scary sister in the cong I was attending who would drink small amounts of hydrogen peroxide for five days, every month, to "cleanse" her system. She would look very weak, pale and unwell during this time and would make a big show of it, claiming that "you have to feel worse for a while in order to get the benefits" . She strongly recommended this and many other kooky home remedies, even recommending people give up all their prescritpion meds. She had quite a following amongst the hypochondriacs. She is an elder's wife.
IMO this woman is dangerous.
