Applying Swedish Bitters on a mole over a period of several day will cause it to fade and disappear.
I discovered this back in 96 when I had a mole on the back on my hand which started to change shape and grow. I took a band-aid, put a couple of drops of Swedish Bitters on the cotton part and stuck it over the mole. Every day I changed the dressing, and watched as it grew smaller until about a week later, it had completely disappeared.
I have noted, however, this only occurred with Swedish Bitters made to the exact recipe mentioned in Maria Treben's book, Health Through God's Pharmacy. Oddly enough, the commercial brands do not have the same effect. The only difference is the camphor content which is said to be a possible hazard to women.
