This section answers many of the most common questions people have about the herb jiaogulan.

What is Jiaogulan?

What is Jiaogulan?

 Jiaogulan (Latin name: Gynostemma pentaphyllum) is a low-lying
vine from the Cucurbiticeae family of plants. Jiaogulan is indigenous to Southern China but is now cultivated widely throughout Asia, most notably in Thailand and Vietnam.Jiaogulan is produced primarily as an herbal tea and is also available as both whole leaf
and extracted supplement.

Traditional Chinese Medicine recommends Jiaogulan as a general health tonic and in some regions of china it is called Xian Cao (the Immortality Herb) due to its association with longevity and robust health.

The plant first came to the attention of modern researchers
in the 1970’s as a result of China’s first nationwide census. Demographers noted a statistically significant higher percentage of centenarians in two small Southern provinces. The Chinese
government dispatched a team of researchers whom ultimately conducted a ten-year study.The researchers attributed the unusual longevity in those areas to the regular traditional consumption of jiaogulan tea in those areas. Following these findings,  Dr. Jialiu Liu of Guiyang Medical College conducted extensive research including human clinical studies into the plant. His research identified active ingredients in Jiaouglan that provided a broad range of health benefits, including, cardiovascular health, improved immune systems, protection from and faster recovery from oxidative stress, cancer protection and improved blood flow
resulting in better mentation and organ health. Dr. Lu authored a book with American researcher Michael Blumert extolling jiaogulan as the Herb of Immortality.

Jiaogulan was also the subject of extensive research in the 1980’s by Japanese researchers who, noting the natural sweetness of jiaogulan, hoped jiaogulan could be developed as a natural sweetener. While the project was unfruitful, Japanese researchers also compiled an impressive list of provenhealth benefits.

Today herbalists recommend jiaogulan for three main health
benefits.

1) Put your body in
the optimal state of balance –

Adaptogens are a class of herbs identified by herbalists as helping the human body maintain a state of “homeostasis”, i.e. balance. The mechanisms vary from herb to herb but primarily adaptogens work by supporting the neuroendocrine system. The neuroendocrine system is the combined systems of hormones and nervous system. Modern researchers have proclaimed jiaogulan the world’s most potent adaptogen. One theory is jiaogulan’s stimulation of Nitric
Oxide production improves the overall function of the neuroendocrine system

2) Reduce blood pressure
and improve cardiovascular health
– Chinese research has proven that jiaogulan stimulates the human body to increase production of nitric oxide. Nitric oxide is a natural vasodilator. Increased vascular size makes it easier for the heart to pump blood throughout the body and reduces blood pressure. The increased blood flow also mitigates the  harm from arterial build up due to arteriosclerosis.

Jiaogulan also reduces cholesterol. Since high cholesterol is the number one cause of clogged arteries, there is a double benefit to cardiovascular health. Blood vessels are less likely to develop obstructions and, when they do occur, the impact is mitigated by increased blood vessel size.

Increased Nitric oxide production is also the reason jiaogulan is popular with endurance athletes. The increased blood vessel size increases oxygen flow which directly result sin greater endurance. This increased blood flow is also believed beneficial to sufferers of Erectile Dysfunction and to improved mentation in the elderly.

3) Fight the effects
of aging and strengthen the immune system –
Most people have read about the
health benefits of antioxidants. One can hardly visit the grocery store without being bombarded by marketing messages on products touting their high antioxidant content. Marketers have gone so far as to co-op a formerly scientific measure of antioxidant called the ORAC scale. ORAC stands for Oxygen Radical Absorbance Capacity. It is a measure of the anti-oxidant levels in a food. Marketers engage in heated debate over whose product as the higher ORAC value.

But the reality is that most of the health benefit of antioxidants consumed in food is wasted. When we digest food only a small
percentage of the antioxidants present actually survive the digestive process and enter the blood stream where they can be distributed throughout the body and help destroy free radicals and boost the immune system.

However, there is a solution. The human body does produce
it’s own natural antioxidants, two enzymes Super-Oxide Dismutase (SOD for short) and catalase.

These internally produced antioxidants are crucial to all
animal life as they are the main mechanism of cleansing and protecting the body from free-radicals created during the metabolization of foods. Increased productions of these
internally produced antioxidants is far more effective than consumption of antioxidants because the internally produced antioxidants to not undergo digestion and are therefore 100% bioavailable.

Research proves jiaogulan increases SOD production in
humans. Researchers speculate this is the primary reason the herb is so strongly associated with longevity is Traditional Chinese Medicine. There has also been substantial research in Canada using jiaogulan to support the compromised immune systems of chemotherapy patients. This improved immunity has resulted in jiaogulan’s popularity as a immune support supplement during cold
and flu season.

Recent media attention has been focused on jiaogulan for
weight loss. Researchers in Korea have determined that jiaogulan is a potent activator of the AMPK enzyme in humans. AMPK plays a crucial role in the regulation of human metabolism. In one Korean study, obese men were given jiaogulan extract for 14 weeks. The placebo group experienced no significant change. However the jiaogulan group lost an average of 2Kg., saw reduction in their waistlines, improved body mass index and lower cholesterol levels.

Jiaogulan is a perennial and can be harvested throughout the
year. Jiaogulan Tea is produced by a three-stage process. The plant is
harvested and stems removed by hand. The plant is quickly pan dried to form the typical 5 leaf clusters of dried tea and then air dried on raised platforms with forced air. The resulting tea is simultaneously slightly bitter and slightly sweet. The tea is popular in Southern China often consumed as a substitute for tea from Camelia sinensis. Jiaogulan can also be consumed as a supplement,
in extract form, as a tincture and the raw leaves may be added directly to foods.

What is a saponin?

Saponin: a class of chemical compounds, one of very many secondary metabolites found in natural sources, with saponins found in particular abundance in various plant species. Specifically, they are amphipathic glycosides grouped phenomenologically by the soap-like foaming they produce when shaken in aqueous solutions, and structurally by their being composed of one or more hydrophilic glycoside moieties combined with a lipophilic triterpene derivative (see Hostettmann & Marston 1995[1], and Cornell 2008[2]) (from Wikipedia) Click to read the wikepedia entry in full.

How do you make jiaogulan tea?

Jiaogulan Preparation:Jioagulan is consumed as a tea, as capsules or simply raw or dried. Opinions vary on the method of preparation as a tea and seem to be a mater of personal preference. Some experts recommend treating jiaogulan similarly to a high quality green tea, i.e. brewing temperatures between 140 deg and 160 deg and brewing times under 2 minutes. Other’s prefer a much longer brewing time to maximize the extraction of the beneficial saponins.

What is jiaogulan good for?

Jiaogulan is first and foremost a delicious tea and is widely consumed purely for the taste. However, research suggests that is may also be beneficial for: high blood pressure, cancer therapy, impoved athletic performance, reducing stroke and heart attack risk, erectile disfunction, diabetes, insomnia, fatigue and reducing cholesterol. See the individual health links below for more information.

Where did jiaogulan come from?

Jiaogulan (latin: Gynostemma Pentaphyllum) is low growing five-leafed vine in the same family as cucumber plants and a variety of gourds. The leaves of the jiaogulan plant have been consumed as a tea in southern China for centuries. Residents in the Guangxi and Shicuan provinces called the herb Xiancao which translates as, “the immortality herb” and it was well known for its many beneficial properties. However, jiaogulan did not come to the attention of the medcial reseacrh community until 1972 when Japanese researcher Dr. Mashiro Nagai investigated using jiaogulan as an alternative to artificial sweeteners. While there is a sweet variety of jiaogulan, it did not prove to be a viable sugar substitute. However, Dr. Nagai’s research did identify several intiguing properties in jiaogulan, most notably an unprecedented number of natural saponins.

Researchers again noticed jiaogulan as a result of the Chinese census in the 1970’s. Demographers noted an unusual concdntration of centenarians (people of age greater than 100) in Guangxi and Shicuan provinces. Dr, Jialiu Liu was sent to these provinces to investigate. His research found that the only common factor amongst the centenarians was high daily consumption of tea made from jiaogulan. The Chinese launched an extensive multi-year study of jiaogulan resulting in most of the information we have today regarding the beneficial effect of jiaogulan.

Japanese researchers took up the subject again in 1981 when the previous Japanese research caught the attention of Dr. Tsunematsu Takemoto. His research confirmed many of the Chinese findings and provided much of the detailed biochemical analysis available regarding jiaogulan.
