This invention relates to the use of zinc salts as anti-viral agents in sexual lubricants. A zinc salt which releases divalent zinc ions in an aqueous carrier fluid is provided in a sexual lubricant formulation which is spread on the genitals before sexual intercourse. The mixture is non-irritating, and the zinc ions serve as an anti-viral agent to reduce the risk of contracting genital herpes if a sexual partner is infected. These lubricants may also reduce the risk of infection by other sexually transmitted viral diseases, such as hepatitis, papilloma viruses, and AIDS. A preferred lubricant formulation comprises water, a thickening or suspending agent, a lubricating agent, and a suitable zinc salt. Salts which have been tested and shown to be non-irritating during sexual intercourse include zinc acetate, zinc propionate, and zinc gluconate. Other zinc salts have also been identified which are soluble in water and have low pK values, which indicates a high rate of zinc ion release.
