for the plantar warts, i had to actualluy apply the activated mms (diluted with water) right onto the warts on the feet. after two weeks of topical application in this manner the warts began to shrink and fall off. one of them is still hanging on a little bit,but it won't be long til the last one is gone either.
be careful to dilute the mms if you want to try this method. i used 10 drops with 50drops activator and then about 1/8 th cup distilled h2o for my topical solution.
as far as the sinuses... mine cleared up after the second week on mms(but now i have a cold, so i cannot tell until the cold is gone if my sinuses are still cleared).
maybe long held sinus issues will take longer than 20 some days???
