Traditional Uses

In TCM theory, Da Huang is a bitter-cold herb entering the spleen, stomach, large intestine, and liver channels, traditionally used to purge accumulated heat, cool the blood, and unblock the bowels. It is a key component of classical formulas such as Da Cheng Qi Tang and is often paired with Mang Xiao or Hou Po. Wine-processing is traditionally believed to moderate its purgative strength and direct its action upward.
