Abstract
Abstract Montmorillonite, either alone or when combined with other materials, is highly effective in the treatment of dermatomycosis pedis. Even better results are obtained when the composition contains about 80% montmorillonite, about 20% pyroligneous acid and a very small quantity of papain enzyme. About 0.5% of lysozyme hydrochloride may also be added. The compositions are not only effective for the treatment of both wet and dry athlete's foot, but also in deodorizing the unpleasant odors of socks and the inside of shoes.
