GINSENG: THE EFFECT OF STEAMING
(THIS INCLUDES THE CHINESE AND KOREAN RED GINSENG)
Report Says Hot Steam Dramatically Increases Ginseng's Potency Steaming
ginseng at higher temperatures can boost its potency dramatically, according to
research reported in the current (November 21) issue of the Journal of Natural
Products, a peer-reviewed journal of the American Chemical Society, the world's
largest scientific society.
Ginseng root has been used mostly in Asian cultures for centuries to enhance
physical and mental vitality. The nutritional supplement in recent years has
become widely available in world markets - either dried, or steamed at standard boiling temperatures of 100 degrees Celsius (212 Fahrenheit) - for use
as an antioxidant and blood thinner.
Steaming for approximately three hours at 120 degrees Celsius (248 Fahrenheit)
can multiply the herb's antioxidant qualities by eight times and its ability to
relax blood vessels by up to 32 times, according to researcher Jeong Hill Park
of Seoul National University in Korea.
The hotter steam produced an optimal amount of biological activity from the same
ginseng used in normal supplements, Park found. The higher temperature amplifies
certain ginsenosides - the ingredient believed responsible for ginseng's
sought-after qualities - and generates others not normally found in dried
versions of the root, Park said. "This very simple steaming can
significantly increase the biological activities of ginseng," Park said.
"I believe we can develop more potent health foods or related products
using this process." Such high temperature steaming would be part of the
manufacturing process of "sun ginseng," named after the dark purple
color achieved from the heat, Park said. The additional heating above normal
boiling temperature requires applying pressure to the water. This cannot be done without special equipment,
he said. Ginseng steamed at boiling temperatures is known as "red
ginseng" because of the coloration it assumes. Park reported no negative
side effects from the higher concentration levels produced by the hotter
steaming. As a food supplement, ginseng does not require extensive clinical
trials in the United States. But those taking anti-inflammatory or blood
thinning drugs should be alert to possible interactions, according to health
sources.
