The Bio-Salicin formula is herbal aspirin and is concocted to address pain. We call it the Headache And Pain Formula because the name is ideal for the formula. The ingredients are actually listed on the site on the on-line store (all products). Some of the ingredients include white willow bark, black willow bark, feverfew, poplar, woodruff, wintergreen, peppermint, wood betony, and spearmint.
