  • Cooking da huang and gan cao together for a long time (> 30 minutes) will reduce purgative effects, while cooking short time will cause maximum purgation.
  • Pharmacologically Da Huang has a remarkable laxative effect, and has been shown effective to reduce LV damage in hepatitis.
  • Patients with acute pancreatitis were treated very effectively with a decoction of 30-60g da huang every 1 to 2 hours until symptoms returned to normal.
  • According to Dr. Zhang Ziao Ping a small amount of Da Huang is effective to treat hypertension and LV fire.
  • Mang Xiao is often combined with Da Huang to strongly treat excess constipation due to heat. Both Da huang and Mang Xiao can cause intestinal cramping as they stimulate the movement of the intestines.
