Common Ginseng classification

Common Ginseng classification

According to traditional Chinese medicine, American ginseng promotes yin energy, cleans excess yang and calms the body. The reason it has been claimed that American ginseng promotes yin (shadow, cold, negative, female) while Asian ginseng promotes yang (sunshine, hot, positive, male) is because, according to traditional Chinese medicine, things living in cold places or northern side of mountains or southern side of rivers are strong in yang and vice versa, so the two are balanced.[citation needed] Chinese/Korean ginseng grows in Manchuria and Korea, the coldest area known to many Koreans in ancient times. Thus, ginseng from there is supposed to be very yang.
Originally, American ginseng was imported into China via subtropical Guangzhou, the seaport next to Hong Kong, so Chinese doctors believed American ginseng must be good for yin, because it came from a hot area. They did not know, however, that American ginseng can only grow in temperate regions. Nonetheless, the root is legitimately classified as more yin because it generates fluids.

Most North American ginseng is produced in the Canadian provinces of Ontario and British Columbia and the American state of Wisconsin, according to Agri-food Canada. P. quinquefolius is now also grown in northern China.
The aromatic root resembles a small parsnip that forks as it matures. The plant grows 6 to 18 in tall, usually bearing three leaves, each with three to five leaflets two to five inches long.

Asian ginseng (root)

Ginseng and reishi mushrooms in bottles being sold in Seoul, Korea Panax ginseng is available commercially in four forms: fresh, red, white and sun ginsengs. Wild ginseng is used where available.

Fresh ginseng
Fresh ginseng is the raw product. Its use is limited by availability.

Red ginseng
Red ginseng has been peeled, heated either through steaming at standard boiling temperatures of 100 °C (212 °F), and then dried or sun-dried. It is frequently marinated in an herbal brew which results in the root becoming extremely brittle. It is more common as herbal medicine than white ginseng. This version of ginseng is traditionally associated with stimulating sexual function and increasing energy. Red ginseng is always produced from cultivated roots, generally from Korea.
In 2002, a preliminary double-blind, crossover study of Korean red ginseng's effects on impotence reported it can be an effective alternative for treating male erectile dysfunction, during which 60% of study participants noted an improvement in ability to produce an erection.
Another study reported red ginseng reduced the relapse of gastric cancer versus control.
A study of ginseng's effects on rats found, while both white ginseng and red ginseng appear to reduce the incidence of cancer, the effects appear to be greater with red ginseng.
Another study showed potentially beneficial effects of a combination of Korean red ginseng and highly active antiretroviral therapy in HIV-1-infected patients.
Falcarinol, a 17-carbon diyne fatty alcohol isolated from carrot and red ginseng, was thought to have potent anticancer properties on primary mammary epithelial (breast cancer) cells.[29] Other acetylenic fatty alcohols in ginseng (panaxacol, panaxydol and panaxytriol) have antibiotic properties.

White ginseng
White ginseng, native to America, is fresh ginseng which has been dried without being heated. It is peeled and dried to reduce the water content to 12% or less. White ginseng air-dried in the sun may contain less of the therapeutic constituents. It is thought by some that enzymes contained in the root break down these constituents in the process of drying. Drying in the sun bleaches the root to a yellowish-white color.

Sun Ginseng
Sun ginseng is created from a heat processing method which increases ginsenoside components such as ginsenoside-sub.1] and by steaming white ginseng at a higher temperature than red ginseng. The herb is steamed for three hours at 120 °C (248 °F). Sun ginseng has increased nitric oxide, superoxide, hydroxyl radical and peroxynitrite scavenging activities compared with conventionally processed red or white versions. The increased steaming temperature produces an optimal amount of biological activity due to its ability to amplify specific ginsenosides.

Wild Ginseng

Wild ginseng grows naturally and is harvested from wherever it is found. It is relatively rare, and even increasingly endangered, due in large part to high demand for the product in recent years, which has led to the wild plants being sought out and harvested faster than new ones can grow (it requires years for a root to reach maturity). Wild ginseng can be either Asian or American, and can be processed to be red ginseng.
Woods-grown American ginseng programs in Maine, Tennessee, Virginia, North Carolina, West Virginia and Kentucky,and United Plant Savers have been encouraging the planting of ginseng both to restore natural habitats and to remove pressure from any remaining wild ginseng, and they offer both advice and sources of rootlets. Woods-grown plants have a value comparable to wild-grown ginseng of similar age.
Partially germinated ginseng seeds harvested the previous Fall can be planted from early Spring until late Fall, and will sprout the following Spring. If planted in a wild setting and left to their own devices, they will develop into mature plants which cannot be distinguished from native wild plants. Both Asian and American partially germinated ginseng seeds can be bought from May through December on various eBay sales. Some seed sales come with planting and growing instructions.
