Asian Ginseng
Background
Asian
ginseng is native to the Far East, including China and Korea, and has
been used for health-related purposes for at least 2,000 years. Asian
ginseng is one of several types of ginseng (another is American ginseng,
Panax quinquefolius).
The terms red ginseng and white ginseng refer to Asian ginseng roots
prepared in two different ways. The herb called Siberian ginseng or
eleuthero
(Eleutherococcus senticosus) is
not related to true ginseng.
In
traditional Chinese medicine, Asian ginseng was used as a tonic that
was believed to replenish energy. Today, Asian ginseng is used as a
dietary supplement to improve general well-being, physical stamina, and
concentration; stimulate immune function; slow the aging process; and
relieve various health problems such as respiratory disorders,
cardiovascular disorders, depression, anxiety, erectile dysfunction,
and menopausal hot flashes.
The root of Asian ginseng contains
chemical components called ginsenosides (or panaxosides) that are
thought to contribute to the herb’s claimed
health-related properties.
How Much Do We Know?
There
have been many studies of Asian ginseng in people, but few have been
high quality. Therefore, our understanding of Asian ginseng’s health
effects is limited.
What Have We Learned?
There’s currently no conclusive evidence supporting any health benefits
of Asian ginseng.
What Do We Know About Safety?
Short-term
use of Asian ginseng in recommended amounts appears to be safe for most
people. However, questions have been raised about its long-term safety,
and some experts recommend against its use by infants, children, and
women who are pregnant or breastfeeding.
The most common side effects of ginseng are headaches, sleep problems,
and digestive problems.
Some
evidence suggests that Asian ginseng might affect blood sugar and blood
pressure. If you have diabetes or high blood pressure, consult your
health care provider before using Asian ginseng.
The risk of
interactions between ginseng and medications is believed to be low, but
there are uncertainties about whether ginseng might interact with
certain medications, such as the anticoagulant (blood thinner) warfarin
(Coumadin). If you’re taking medication, consult your health care
provider before using Asian ginseng.
Keep in Mind
Tell
all your health care providers about any complementary or integrative
health approaches you use. Give them a full picture of what you do to
manage your health. This will help ensure coordinated and
safe care.
