have a question from Malaysia -- really, two questions. How is ginseng grown and
harvested in the United States? And is it used as a traditional medicine by
Americans or just Asian-Americans?
growers of American ginseng say it takes five to ten years to produce the best
roots. Ginseng can be grown from seeds or roots. The seeds take two years to
sprout up through the ground. Many growers like to start with two to three year
old roots instead. A warning: the root must not be cut into smaller pieces. It
has to be whole to grow.
needs a place where it will not get much sunshine. It does well in areas of
eighty percent shade. It especially likes to grow in forests. The soil should
be full of loam, a mixture of sand, silt, clay and organic material.
ginseng grows naturally in forests in many eastern states. But wild populations
have been reduced by too much harvesting.
Growers can plant the roots during
spring before they develop buds. If the roots are planted in the fall, they
should be left alone until the following spring. Weeding and watering are not needed
during that time. But the plants should be protected from wildlife.
The University of Maryland Cooperative
Extension explains that forest landowners can grow ginseng using two different
methods. With the wild-simulated method, seeds are planted thinly in the
forest. They are left to grow naturally so the most desirable roots -- those
most similar to wild ginseng -- are produced.
the cultivated method, the ginseng is densely planted in raised beds. But this
process is more costly and labor intensive.
ginseng is planted in the fall. Seven years is the average time to harvest. Experts
at the Ohio State University Extension say most people use a device with a short
handle called a mattock or sang hoe. Extra care is needed not to break up the
twisted, strange-looking roots; that could make them less desirable.
are not the only ones who use ginseng. Some people say it increases their energy.
Others say it helps their memory. Studies have shown differing results about
the health benefits.
products may contain ginseng, but government rules limit health claims that marketers
For example, one company that makes bottles of tea
sells a popular green tea with ginseng and honey. Its Web site simply says: "Just
the right amount of ginseng."
