Gynostemma pentaphyllum or Jiaogulan is a vine that grows natively in Asia. It is considered to be one if not the most powerful adaptogen. Adaptogens may be very useful for protecting the body and mind from outside stressors and decreasing sensitivity to stressful stimuli. People may use Jiaogulan to combat obesity, liver disease, diabetes and high cholesterol. In China, Jiaogulan has traditionally been used to increase endurance, combat fatigue and improve energy. Jiaogulan has some antioxidant properties as well, and could be beneficial in cleansing the liver.
