Dong
quai is a member of the celery family. Greenish-white
flowers bloom from May to August, and the plant is
typically found growing in damp mountain ravines,
meadows, river banks, and coastal areas. The root is
used in herbal medicine.
Dong quai has been used in
connection with the following conditions (refer to the individual health concern
for complete information):
Health Concerns
Anemia (due to
dialysis)
Dysmenorrhea (painful
menstruation)
Menopause
Premenstrual
syndrome
Historical
or traditional use (may or may not
be supported by scientific
studies)
Also
known as dang-gui in Traditional Chinese Medicine (TCM),
dong quai is sometimes referred to as the female
ginseng. In Traditional Chinese Medicine, dong quai is
often included in herbal combinations for abnormal
menstruation, suppressed menstrual flow, dysmenorrhea
(painful menstruation), and uterine bleeding. It is not
used in TCM for treating symptoms associated with
menopause, such as hot flashes. It is also used in TCM
for both men and women with cardiovascular disease,
including high blood pressure and problems with
peripheral circulation.
Active constituents
Traditionally, dong quai is believed to
have a balancing or “adaptogenic” effect on the female
hormonal system. Contrary to the opinion of some
authors, dong quai does not qualify as a phytoestrogen
and does not appear to have any hormone-like actions in
the body. This is partially supported by a double-blind
trial with menopausal women that found no estrogenic
activity for the herb.In Traditional Chinese
Medicine, dong quai is rarely used alone and is
typically used in combination with herbs such as peony
and ligusticum for conditions such as menstrual
cramps.
Dong
quai has been traditionally used as a way to promote
formation of red blood cells, an effect partially
supported in a case study of a man with kidney failure
who had a significant improvement in anemia due to
dialysis while drinking a tea composed of dong quai and
peony. No clinical trials have examined dong quai alone
for this purpose, or for the treatment of other forms of
anemia.
How much is usually
taken?
The
powdered root can be used in capsules or tablets. Women
may take 3–4 grams daily in three divided applications.
Alternatively, 3–5 ml of tincture may be taken three
times per day.
Are there any side effects or
interactions?
Dong
quai may cause some fair-skinned people to become more
sensitive to sunlight. People using it on a regular
basis should limit prolonged exposure to the sun or
other sources of ultraviolet radiation. Dong quai is not
recommended for pregnant or breast-feeding
women.
