Possibly Effective for Peyronie disease: PABA is FDA-approved for use in this condition.
Possibly Ineffective for Hardening of skin and connective tissue (scleroderma): Although PABA is FDA-approved for scleroderma, there is only limited evidence that it is effective. Not all research has shown benefit.
3) Application
PABA is also used to treat infertility in women, arthritis, "tired blood" (anemia), rheumatic fever, constipation, systemic lupus erythematosus (SLE), and headaches. It is also used to darken gray hair, prevent hair loss, make skin look younger, and prevent sunburn.
