It is really true that Boric Acid, Methylene Blue, and Iodine
are 3 of the best antiseptic substances on earth. Boric Acid kill everything, Iodine
almost the same, and MB is also powerfull. The problem is any of them is listed to take internally. People do it by their own responsability, but they can have serious damage. Boric Acid is poison. The same can be say about Iodine. You may tolerate extremely low doses diluted in water, but the problem is to know the right doses. The friendly flora can also suffer serious damage by taking those products. I mean , they kill bacterias. They aren't just antifungals. Another thing is alkalinizing the GI tract. That is against Science
if you want to treat candida. It has been shown that candida mutates to its fungal form when the Ph become more alkaline and lives in its yeast or seed form when the Ph is kept acid. Sodium Bicarbonate has antifungal properties but isn't linked to its alkaline Ph.
