Studies have found it increases the activities ofmacrophage s,T lymphocytes and naturalkiller cells and that it acts as a tumor inhibitor. [Liu et al. "Therapeutic and Tonic effects of Jiaogulan on Leukopenia Patients".] Due to its adaptogenic effects it is frequently referred to as "Southern Ginseng," although it is not closely related to true Panaxginseng . Its adaptogenic constituents include thetriterpenoid saponins gypenoside s which are closely structurally related to theginsenoside s from the well-known medicinal plant ginseng. It has been shown to lowercholesterol levels in human studies. [LaCour, Molgaard and Yi. Traditional Chinese Medicine in the Treatment of Lipidaemia. 1995]The plant is best known for its use as an
herbal medicine intraditional Chinese medicine , although its inclusion inWu Qi-Jun 's 1848 botany book "Zhi Wu Ming Shi Tu Kao Chang Bian" discusses a few medicinal uses and seems to be the earliest known documentation of the herb. Prior to that, Jiaogulan was cited as a survival food inZu 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 theGuizhou Province, where jiaogulan tea is drunk regularly, have a history of living to a very old age.cite book

isbn = 978-0939616428 ] Most research has been done since the 1960s when the Chinese realized that it might be an inexpensive source for adaptogenic compounds, taking pressure off of ginseng stock.Adaptogenic herbs are nontoxic in normal doses, produce a nonspecific defensive response to stress, and have a normalizing influence on the body. They normalize the
hypothalamic-pituitary-adrenal axis (HPA axis). As defined, adaptogens constitute a new class of natural, homeostatic metabolic regulators. However they are also functional at the level ofallostasis which is a more dynamic reaction to long term stress, lacking the fixed reference points of homeostasis. [Robyn Klein (2004). [http://www.rrreading.com/files/Manu%20Allostasis%20and%20Adaptogens.pdf Allostasis Theory and Adaptogenic Plant Remedies] .] Jiaogulan is a calming adaptogen which is also useful in formula withcodonopsis forjet lag andaltitude sickness .Alternate names
