Vitamin E
is one of only a handful of remedies that may
provide some relief for breast cancer survivors who suffer
hot flashes, according to experts from the Mayo
Clinic in Rochester, Minnesota.
Estrogen
relieves hot flashes in most women, but concerns remain over
its use in breast cancer survivors because the
hormone may stimulate breast cancer growth. Similar
concerns limit the use of another group of female hormones,
the progestins, although they are also effective.
When evaluating the advertised effectiveness
of hot flash treatments, the authors state, it is worth noting
that dummy pills, or placebos, relieve hot flashes by at least
half in 20% of the women who take them.
The herb black
cohosh seems to alleviate hot flashes and
other symptoms of menopause, and is approved for this purpose
in Germany.
Vitamin E,
at a dose of 800 international units (IU) per day, is modestly
effective in reducing hot flashes, the team reports,
on average cutting the number of hot flashes by one per day.
Based on their review of the subject,
the authors recommend trying vitamin E for mild hot flashes,
as it
is safe, inexpensive, and has some demonstrated efficacy.
