Natural Foods Merchandiser

Bright Future for Chinese Mountain Herb - a great article published in the Natural Foods Merchandiser. The article states...

"Jiaogulan has no known side effects. Unlike ginseng, children can take it. A typical dose is 1,000 mg per day in the form of tea or in capsules, but much higher doses appear to be safe and effective. Bulk Jiaogulan is not commonly available in America (we are trying to change that!), but it can be found prepackaged. Because of its natural sweetness, it is delicious as a tea."


UC Berkeley

Oxidants, Antioxidants, and the Degenerative Diseases of Aging - a UC Berkeley 'heavy weight' article with all the big scientific words. The article states...

The degenerative diseases associated with aging include cardiovascular disease, immune system decline, brain dysfunction, and cataracts.

Small molecule dietary antioxidants such as Vitamin C, Vitamin E, carotenoids, (and Jiaogulan) have generated particular interest as anticarcinogens and as defenses against degenerative diseases.

Antioxidants therefore can decrease mutagenesis, and thus carcinogenesis, in two ways: by decreasing oxidative DNA damage and by decreasing cell division.


Free-Radicals Website

What is an Antioxidant? This site is written at a child's level, however, even grown-up kids can benefit. A nice explanation of the importance of Antioxidants in the battle against Free-Radicals. The site states...

One of the most powerful warriors in this struggle against the Free Radicals is Team Antioxidant and its members Vitamin C, Vitamin E and The Carotenoids. Team Antioxidant comes to the rescue by donating an electron to Free Radicals, converting them back to stable oxygen molecules. This helps keep your body healthy, and prevents cell and tissue damage. Antioxidants live in the foods and vitamins you eat, waiting to enter your body and save the day.

Herbal Heart Defender
This Asian remedy boosts energy too

Jiaogulan (Gynostemma pentaphyllum) is a remarkable herb that targets the key components of heart disease. Its compounds sweep up free radicals (unstable molecules that damage or destroy healthy cells), reduce pressure within the blood vessels, and lower the production of bad LDL cholesterol.

As if that wasn't enough to make it an impressive heart herb, jiaogulan (pronounced gee-ow-goo-lahn) also helps deal with the effects of stress, which can be a major element in the development of heart disease. Jiaogulan and other adaptogens like it make the body more resistant to stress.

As a bonus, this herb increases energy levels. But unlike stimulants that may actually damage blood vessels, jiaogulan makes the cardiovascular system stronger while increasing your get-up-and-go.

potThailand research on Gynostemma Pentaphyllum Makino

Hypoglycemic Activity of Extract from GP Makino

Gynostemma pentaphyllum Makino., (family Cucurbitaceae), an indigenous plant of Southeast Asia has been used in folk medicines to alleviate symptoms and diseases including cough, migraine, insomnia, hypertension and diabetes mellitus.

Hypoglycemic activity of G. pentaphyllum has been found in experiments determining effect of G. pentaphyllum on blood glucose of normoglycemic rat, and glucose tolerance test. However, the hypoglycemic activity of G. pentaphyllum was not apparent in alloxan-induced diabetic rats. The findings indicate that the hypoglycemic activity is due to an ability to stimulate insulin release from the pancreas but not insulin like activity. Results from the glucose tolerance test of which G. pentaphyllum was administered simultaneously with a glucose load suggest that G. pentaphyllum may also exhibit an inhibitory effect on glucose absorption from the gastrointestinal tract. Additionally, the cholesterol lowering activity of G. pentaphyllum was detected.
