These patches are drug free and a simple alternative to taking Saw Palmetto tablets orally. Saw Palmetto Patches are not a medicine. We only use totally natural ingredients. Usage It could not be easier! Just apply one patch to a relatively hair free part of your body (the inner arm, lower back or shoulder are ideal), and change the patch at the same time every day. Any residue or adhesive left on the skin may be washed off with warm soap water.
