Panax vietnamensis (Vietnamese: Sâm Ngọc Linh) is a species of ginseng in Nam Trung Bo and Tay Nguyen regions of Vietnam, especially in mount Ngọc Linh in Đăk Tô District, Kon Tum, a mountain whose name derives from the ginseng that grows there and in Trà My District of Quảng Nam Province. Besides these regions, Panax vietnamensis can be found in Mount Ngọc Lum Heo in Phước Lộc Commune, Phước Sơn District and in the Mount Ngọc Am of Quảng Nam Province. It grows at elevations between 1,200 and 2,100 m under the leaf canopy of jungles and in wet areas beside running water.

[edit] Growing
Tra Linh Commune, in the central Ngoc Linh Mountainarea, is considered the pioneer of ginseng growing in Vietnam. In 1979, the government of central Quang Nam Province established the Tra Linh Drug Materials Farm in Tra Linh Forest on Ngoc Linh Mountain. The farm grew the first cultivated Ngoc Linh ginseng, yet the enterprise was not properly developed until 1995, when the local department of science and technology invested in the farm. Since then, locals from Tra Linh Commune and surrounding areas, including places in central Kontum Province, have been growing the medicinal plant. The commune’s Mang Lung Village now has around 5,000–10,000 ginseng plants between two and eight years old (ginseng is harvested at age seven), with 90 percent of local families growing the crop.[1] [2]
[edit] DNA
Panax vietnamensis is sympatric with other Panax species and has a close relationship with P. japonicus var. major and P. pseudo-ginseng subsp. himalaicus.[3]
[edit] Medicinal uses
Ethnobotanically it is a secret medicine of the Sedang ethnic group as a miraculous, life-saving plant drug used for the treatment of many serious diseases and for enhancing body strength in long journeys in high mountains.[citation needed]
In tests, Vietnamese ginseng extract attenuated psychological stress-induced antinociception, produced the protective effect against psychological stress-induced gastric lesions, and restored the stress-induced decrease in pentobarbital sleep to the normal level.[citation needed] This action was not observed on Panax ginseng extract. Vietnamese ginseng extract showed inhibitory activity on Epstein-Barr virus early antigen (EBV-EA) activation induced by TPA. This activity was concentrated to the saponin fraction and especially, major saponin, majonoside R2 exhibited the strongest activity.[4]
