Gynostemma pentaphyllum, also called jiaogulan (Chinese: 绞股蓝; pinyin: jiǎogǔlán, literally "twisting-vine-orchid") is an herbaceous vine of the family Cucurbitaceae (cucumber or gourd family) indigenous to the southern reaches of China, southern Korea and Japan. Jiaogulan is best known as an herbal medicine reputed to have powerful antioxidant and adaptogenic effects that increase longevity.

Jiaogulan is a vine hardy to USDA zone 8 in which it may grow as a short lived perennial plant. It can be grown as an annual in most temperate climates, in well-drained soil with full sun. The plant is dioecious, meaning each plant exists either as male or female. Thus, if seeds are desired, both a male and female plant must be grown. Unlike most plants of the Cucurbitaceae family, jiaogulan does not show toxicity.[citation needed]
The plant is best known for its use as an herbal medicine in traditional Chinese medicine. A botany book by Wu Qi-Jun from 1848 Zhi Wu Ming Shi Tu Kao Chang Bian discusses a few medicinal uses and seems to be the earliest known documentation of the herb. Jiaogulan had been cited previously as a survival food in Zu Xio's 1406 book Materia Medica for Famine. Until recently it was a locally known herb used primarily in regions of southern China. It is described by the local inhabitants as the "immortality herb", because people within Guizhou Province, where jiaogulan tea is drunk regularly, are said have a history of living to a very old age.[1][2]
Jiaogulan is most often consumed as an herbal tea, and is also available as an alcohol extract and in capsule or pill form.[3] It is believed to be an adaptogen and antioxidant.[citation needed] Because of its putative adaptogenic effects, it is frequently referred to as "Southern Ginseng," although it is not closely related to true Panax ginseng. Its chemical constituents include the triterpenoid saponins gypenosides which are closely structurally related to the ginsenosides from the well-known medicinal plant ginseng.[citation needed] Jiaogulan is also believed to have calming effects and to be useful in combination with codonopsis for jet lag and altitude sickness.[2] Most research has been done since the 1960s when the Chinese realized that it might be an inexpensive source of adaptogenic compounds, taking pressure off of the ginseng stock.
Western languages such as English and German commonly refer to the plant as jiaogulan. Other names include:[4]
Jiaogulan tea is also marketed in the United States under the trade names Panta tea or Penta tea, depending on the supplier.
