The science behind Jiaogulan
More research is needed. Jiaogulan is an herbal supplement and
not a medicine, treatment or cure. However it may be a helpful supplement to cancer
Potential Direct Inhibitory Effects on Tumors
Wang, C. et al. A
preliminary observation of preventive and blocking effect of
Gynostemma pentaphyllum (Thunb) Makino on esophageal cancer in rats.
Hua Xi Yi Ke Da Xue Xue Bao. 1995
In this study researchers found that rats injected with a known
carcinogen developed fewer and less frequent tumors when allowed to ingest water
infused with Jiaogulan. The development of cancer was also delayed by about 6
weeks suggesting to the researchers that Jiaogulan was having a direct
Study concludes Jiaogulan kills liver cancer cells
Chen JC et al. Gypenoside induces apoptosis in
human Hep3B and HA22T tumour cells. Cytobios. 1999.
Dr. Chen and his team, found that human liver
cancer cells treated for two days with gypenosides (the active ingredients in
Jiaogulan) died via apoptosis. Normal cells in the cancerous tissue sample
Qwa-fu Wang, et al.
Regulation of Bcl-2 family molecules and activation of caspase cascade involved
in gypenosides-induced apoptosis in human hepatoma cells. Cancer Letters
Reseachers at the Chinese Medical College
in Taiwan studied the mechanism by which Jiaogulan kills liver cancer
cells. They confirmed the results of the above study and identified a potential
mechanism for this effect.
Scientists say Jiaogulan has "a positive
Zhou Z. et al. Effect of gynostemma
pentaphyllum mak on carcinomatous conversions of golden hamster cheek pouches
induced by dimethylbenzanthracene: a histological study.The Journal of
Chinese Medicine 1998.
Dr. Zhou at Shanghai Medical University gave
hamsters a known carcinogen. A control group did not receive Jiaogulan and
developed cancer as predicted. Two other groups were given Jiaogulan orally.
Both groups showed remarked slowing of the cancerous growth. The inhibitory
effects were directly correlated with the dosage amounts of Jiaogulan.
Improved Immune Systems in the Presence of Radiation!
Chen WC et al. Protective effects of
Gynostemma pentaphyllum in gamma-irradiated mice. American Journal of
Chinese Medicine 1996.
In this study researchers were interested in the
effects on the immune system of radiation. They subjected mice to gamma
radiation. They found reduced white blood cell counts as a result of the
radiation treatment. However, Mice given Jiaogulan recovered their white blood
cell counts more quickly.
Jiaogulan found to inhibit cervix cancer!
Chiu TH et al.N-acetyltransferase is involved
in gypenosides-induced N-acetylation of 2-aminofluorene and DNA adduct formation
in human cervix epidermoid carcinoma cells (Ca Ski). In Vivo May 2003.
Dr. Chiu and his team studied the inhibitory
effects of gypenosides on human cervix cancer. They found there is indeed an
inhibitory effect. The mechanism appears to be that gypenosides inhibited NAT
mRNA expression in human cervix cancer cells.
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.
