Vitamin E.

Vitamin E has been claimed to prevent, ameliorate, or cure skin disease, 
warts, ulcers, strabismus, baldness, frostbite, arthritis, jaundice, muscular dystrophy, diabetes, liver 
dysfunction, thyroid disease, sexual impotence, and aging. The vitamin has recently 
been added to cosmetics, used as a deodorant, and alleged to 
be an effective antidote to air pollution. There is no evidence 
that large doses of vitamin E are effective for the prevention 
or treatment of heart disease or any other human disorder, except 
in premature infants and possibly in patients with diseases that impair 
fat absorption. Adverse effects, though rare, have resulted from ingestion of 
large doses of vitamin E.
