which has the original formula with LUGOL's IODINE
How many people have died with false formula's and how has this contributed to discredit the Hoxsey cure?
Potassium Iodide 16% Hoxsey Solution

The ingredient particulars of the original internal Hoxsey formula have been
well-documented, and many formulas (including Hoxsaic) that use his name or allude to his work leave out, for one reason or another, a crucial ingredient that even Hoxsey himself said was crucial to making his internal formula "work" --- potassium iodide, 7.7% to be precise, in his original tonic. (We discussed this ingredient and its use quite briefly in our
Lugol's Iodine page, which users of this formula are advised to read in its entirety.) What we have done, for those who want to try or experiment with the original Hoxsey formula, is created stabilized potassium iodide formula that is calibrated so that if you add it 50/50 with Hoxsiac or similar cancerolytic herb formulas, you will be imitating, in exact proportion, the potassium iodide in the original formula. Note that this product is nowhere near as strong, as an oxidizing agent, as Lugol's, nonetheless, you should take care in using this formula. Like all nutrients, you can overdue your iodine intake (Dr. J.C. Jarvis, M.D. notes, among other things, that a "moist nose" will develop if you overdue it -- again, discussed on the
Lugol's page. U.S. Users: please note the usual legal caveat found in the upper right hand corner of this page.
Ingredients: Distilled water, potassium iodide (16%), grain alcohol (10% by weight, 96% purity).
