PABA (Para-Aminobenzoic Acid)
En Español (Spanish Version)
Principal Proposed Uses
Other Proposed Uses
Para-aminobenzoic acid (PABA) is best known as the active ingredient in sunblock. This use of PABA is not really medicinal: like a pair of sunglasses, PABA physically blocks ultraviolet rays when it is applied to the skin.
There are, however, some proposed medicinal uses of oral PABA supplements. PABA is sometimes suggested as a treatment for various diseases of the skin and connective tissue, as well as for male infertility. However, most of the clinical data on PABA comes from very old studies, some from the early 1940s.
