I have a skin allergy,that a dermatologist identified as being eczema, It appears between my knee and ankle on my left leg. over the past 40 years it started about the size of a quarter and for the past 10 or 15 years had grown to cover and area of 4in.by 4 in.....I started taking the charcoal capsules twice a day, each capsule aprox 280 milligrams..the lesion has shrunk to about the size of a quarter..no more itching and burning etc,also whenever i feel an sinus allergy attack i take the charcoal..i reduce the amount that I take when the symptoms reduce.
