bitter.
- 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.

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

of the intestines.
