Wommie cannot legally make any medical claims on any of her products. Having said that, however, I wish to share something that you may find of value.
ANYthing hard and lumpy that I, my family, or my dogs, have had, that I have applied Iodine to, has gotten softer...and the lumps have dispersed.
I got hit with a broomstick (the most recent one) on my forehead - and got a "goose-egg bump" outta the deal - carefully painted magnascent on it and it was gone in a few days. (HUGE bump!)
Dog had some hard lumpy tissue develop around her stitches after her spay operation - painted it with Trapper's SSKI /2% mix the first time and it was gone overnight - two nights later another hard lump developed - painted it with my detoxified Iodine this time - again - hard bump was gone overnight.
I was taking Iodine ORALLY when all my breast cysts disappeared (well, the ones I could FEEL anyways) within six months...others were reporting ovarian cysts disappearing within 3 to 12 months - a lot of these posts were posted within the last 4 years...but the most exciting years (to me) were still the first two (07 & 08) when a LOT of us were starting out and discovering this wonderful-ness together.
Iodine busts things up - in a good way!
I cannot say for sure that it will work, but if I had ANY kind of cyst on my wrist, I'd be painting it (and still be taking my iodine orally, as well). But I am NOT telling YOU what to do. I am just telling you what I'D do. ;^)
Now, the cool part of W's salve is that - well, it's a SALVE! The iodine will disperse and soak into the part of the body it is slathered on in a more deliberately-timed manner...slowly overtime. I believe it would be excellent. I know that when I made her salve myself it was absolutely WONDERFUL for ANY condition of my skin!
