The science behind Jiaogulan
More research is needed. Jiaogulan is an herbal
dietary and
not a medicine, treatment or cure. However it may be a helpful supplement for people with
diabetes.
Improved Glucose Tolerance and Insulin Levels
Åke Norberg, et al. A Novel Insulin-releasing Substance, Phanoside, from the
Plant Gynostemma pentaphyllum. Journal of Biological Chemistry. 2004.
- Researchers from the
Karolinska Institute in Stockholm, Sweden and from Hanoi Medical University,
Hanoi, Vietnam teamed up to research the effects of Jiaogulan on insulin
production. they isolated a new gypenoside (the generic name for the
active ingredients in Jiaogulan) that appears related to insulin production.
I laboratory studies they found that when pancreartic cells from rats were
stimulated with this gypenoside they produced insulin. the researchers followed
up by giving the isolated gypenoside orally to hyperglecemic rats. The rats had
improved glucose tolerance and the insulin levels in their blood increased.
Lower glucose, insulin and triglycerides.
Cheng, H.W. et al. The effect of
gypenosides to lower the hyperglycemia in rats with diabetes melllitus.
Chinese Journal of Diabetes Melllitus. 1997
Dr. Cheng and his team gave Jiaogulan extracts to
rats with diabetes. After four weeks they measured "markedly lower" blood
glucose, insulin and triglycride levels.

89%
effective
Cheng, H.W. et al. Clinical study on the
effect of gypenosides on hyperlipaemia in 46 patients with diabetes mellitus.
Journal of Applied Combined Chinese and Western Medicine. 1997
In a follow-up to the above study, Dr. Cheng gave
jiaogulan extracts to 46 patients with diabetes. After just 8 weeks 89.1% of
patients showed improved glucose, insulin and triglyceride levels.
Our Jiaogulan tea is grown under strict
organic quality control standards in the highlands of Thailand. We dry the tea
in loose leaf form at the farm and we ship fresh to the US each month to
maintain maximum potency. Unlike many herbals, Jiaogulan tastes great hot or
cold. We were awarded the prize for best tasting tea in Thailand by the Thai
Agriculture Ministry.
