potAre there Scientific Studies that prove the effectiveness of Jiaogulan and gypenosides?

Many systems within the body may be supported by adaptogens and antioxidants. Typical ways that adaptogens and antioxidants may work within the body are listed below.

All of the potential effects of adaptogens and antioxidants (including gynostemma pentaphyllum) on the systems within the body need more human studies to prove or disprove.

The list below includes are partial composite of previous studies of Jiaogulan and its chemical components.

1. Antioxidant. This herb has been shown in tests to lower the amount of Superoxide radicals and hydrogen peroxide in certain white blood cells, an excellent indicator of antioxidant activity. Jiaogulan also has the remarkable property of increasing endogenous SOD (Superoxide Dismutase) in the body. SOD is one of the body's most important antioxidants and studies show that charting SOD levels in various animal species is a reliable indicator of their longevity. Trials in humans showed that SOD levels may return to youthful levels after taking 20 mg of Gypenosides (active elements in Jiaogulan) daily for one month.

2. Adaptogen. Jiaogulan may modulates the nervous system. It calms an overexcited nervous system and stimulates a depressed one. 300 professional athletes were the subjects of a study. All the athletes reported that taking this herb before competition made them vigorous and alert with quick reflexes. Yet it also made them less nervous.

3. Insomnia. 112 cases of insomnia reported a sleep improvement of 89 to 95 percent.

4. Blood Pressure. 223 patients were divided into three groups. One group took Ginseng, the next took Jiaogulan and the last took the blood pressure medication, Indapamide. The effectiveness was rated at 46% for Ginseng, 82% for Jiaogulan and 93% for Indapamide. This herb may modulates blood pressure, lowering it when it is too high and raising it when it is too low.

5. Cardiac function. Jiaogulan may increase cardiac function. In a study combined with some other herbs, heart stroke volume increased 37% and cardiac output increased by 21% on the average. Ejection fraction increased by 13%. Subjects had normal blood pressure which did not change although heart rate decreased by 10%.

5. Cholesterol. Jiaogulan may lower total cholesterol, LDL cholesterol (the bad stuff), and raises HDL cholesterol (the good stuff). More than 20 papers have been published on the subject with effectiveness reported as ranging from 67 to 93%. It may also inhibits platelet aggregation, which lessens the chance of a stroke or heart attack.

6. White blood cells. Jiaogulan may increase the production of white blood cells in white cell deficient patients.

7. Immunostimulant. This herb may modulates lymphocyte formation and increases lymphocyte activity. It was also found to possible enhance the activity of NK (Natural Killer cells).

8. Diabetes. A study of 46 patients with Diabetes Mellitus showed a possible improvement of 89% in their condition. Another study also showed satisfactory results.

9. Hepatitis B. 100 patients were given Jiaogulan for 3 months. Effectiveness was rated at 89%. Another study of 200 patients yielded similar results. Other studies showed the possibility to protect the liver from various toxic chemicals such as carbon tetrachloride.

10. Bronchitis. A study of 86 cases of chronic bronchitis had an effectiveness rate of 93%. Another study of 96 cases had a 92% effectiveness rate.

Circulatory System: support the body’s blood and related systems such as the liver, glands, nerves and general circulation

Immune System: supports the immune system, adrenal function, provides energy/metabolism boost, nurtures central nervous system/heart connection, creates unfavorable environment for viruses

Nervous Fatigue: Supports adrenal function, provides energy/metabolism boost, nurtures central nervous system/heart connection

Digestive System: digestive and detoxifying functions of the body, including the urinary system

Liver Balance: Supports Liver Health, Relieves Stress, For Occasional Irritability

Spleen Activator: Nourishes Spleen Function, Supports Pancreas, Relief of Occasional Nighttime Leg Cramps

Urinary System: Kidney Activator: designed to support the urinary and lymphatic systems and structural system

All of the above potential effects of adaptogens and antioxidants (including gynostemma pentaphyllum) on the systems within the body need more human studies to prove or disprove.
