Several years ago I was diagnosed with seborrheic keratosis in several places, and the Doctor used liquid nitrogen to freeze it. It was very painful and it came back. Next I tried burning it off myself using a soldering iron. It was much less painful but eventually came back, perhaps not as fast as before. So next I used some Chaga tea and extract, I put it on once a day for several weeks which actually made it smaller (NO PAIN) but it didn't completely go away. Next I tried Methylene blue (You can buy this for fish in the pet store to treat fungal infection) I suspected the Seborrheic keratosis is fungal in triggering it because it seems to come out in dark moist areas of the skin, especially on my back because I sleep on my back and sweat at night.
The methylene blue worked well. Just one dose and it dried up and fell off. But eventually came back and I had to repeat it. Since the MB stains I was looking for another cleaner remedy. I tried Garlic cloves, a slice taped to it, and I did seem to make it smaller after a few days of treatment, but I wanted something easier.
Now I tried my best cure yet:
I mixed up DMSO (Pure) with distilled water 50/50 in a 2 oz dropper bottle with 1/8 tsp pure potassium Iodide crystals and 500 mg niacin. I put this on once a day after my shower each eve. It was clean and didn't stain anything. The spots slowly got smaller & after a month are about 1/3 the original size or the smaller ones are gone completely. I am keeping this up until all are gone. I am also going to do some candida detox protocols to get rid of the systemic fungal. It also got rid of my brown liver spots when I used it on them.
