Abstract
Ointment compositions for the treatment of styes and related infectious conditions of the eyelid. The ointments contain an emollient base, including white petrolatum, mineral oil and microcrystalline wax, as well as boric acid, wheat germ oil and mercuric oxide, the concentration of boric acid in the ointment is about 2-10% by weight, as is the concentration of the wheat germ oil, while the mercuric oxide is present in a concentration of about 1-1.2% by weight. The wheat germ oil enhances the anti-bacterial potency of the mercuric oxide, and the boric acid stabilizes the mercuric oxide in the presence of the wheat germ oil to prevent discoloration of the ointment.
