Codonopsis javanica (Blume) Hook.f. & Thomson, 1855 |
The Vietnamese dangshen (Codonopsis javanica) is a perennial species of flowering plant in the bellflower family Campanulaceae. It is native to Vietnam as well as many other parts of Asia, where it grows in forests, meadows, and scrub.
In traditional Vietnamese and Chinese medicine, the root of Codonopsis pilosula (Vietnamese: đẳng sâm, Chinese: 党参/Dǎngshēn) is used as a medicinal herb. In Vietnam, Codonopsis javanica is also known as đảng sâm, or as đảng sâm nam (southern dangshen) to differentiate the two species. Other local names include sâm dây (vine ginseng).
C. javanica is distributed quite widely from the northern region to the southern central provinces of Vietnam such as Kon Tum, Lam Dong, Lao Cai, Lang Son, Lai Chau...
Uses
C. javanica and other Codonopsis species have been used to treat diabetes and other diseases. The extracts of C. javanica possess insecticidal action against tiger mosquitoes Aedes albopictus.[1]
According to a survey by Nguyen, et al. (2014), C. javanica is a traditional medicine plant used by the K’Ho people in the buffer zone of Chu Sang Sin, the national park in Vietnam. Nowadays, C. javanica has been used in high demand not only as medicine but also as a daily food supplement. Due to overexploitation and deforestation, the reserves of medicinal plants are decreasing. For many years, C. javanica has been included in Vietnam’s Red Data Book and recognised as a priority target for conservation action.[2]
Trinh Thi Huong et. al. evaluate that C. javanica adventitious root biomass contains alkaloid, carbohydrate, saponin, phenolic compounds, flavonoid, fixed oil, fats, gum, and mucilage. The adventitious root biomass presented polysaccharides (16.98%), polyphenol (1.876 mg GAE/g DW), and the IC50 value was 2.44 mg/ml. These results suggest C. javanica be a potential material source in traditional treatment against various diseases affecting humans and animals. [3]
