It treats blood disorders of the Spleen; it treats eye pain caused by excessive Fire, removes blood stasis and blood heat, thus its strengths lie in purging the Liver, moving blood, and clearing heat. If the condition is not one of excess solid-heat, it should not be taken.

Main Indications (Integration with Smallpox and Measles): It has a purgative effect but no tonifying effect; it benefits the nine orifices and urination, attacks blood bi to relieve pain. It specifically resolves blood heat, smallpox toxin, and heat toxin; it transforms macules and reduces swelling simultaneously, purges heat from the blood, and moves stagnation in the blood.

It inherits the clear and cold qi of Heaven and Earth and possesses the nature of Metal; therefore, its taste is bitter and neutral, its nature is greatly cold, and it is non-toxic. It enters the Hand Taiyin Lung Meridian, Hand Shaoyin Heart Meridian, Hand Taiyang Small Intestine Meridian, and Hand Yangming Large Intestine Meridian, and also enters the Foot Shaoyang Gallbladder Meridian. Its nature is clear and austere, so it expels pathogens; its bitter taste dries dampness; its yin-cold nature overcomes heat, thus it eliminates various pathogenic heat and damp-heat. For conditions of pathogenic heat and excess syndrome, raw herb is suitable; for Spleen and Stomach dysentery, wine-fried herb is suitable; for calming the fetus, thick and solid strips are suitable, soaked in wine and fried until yellow.

Huangqin (Radix Scutellariae), purges Lung Fire, eliminates phlegm, facilitates Qi movement, removes damp-heat, preventing accumulation on the muscle surface, purges Large Intestine Fire, nourishes Yin, retreats Yang, and further nourishes the source of transformation, keeping the Bladder full.

Collectively, it eliminates all types of heat, achieving complete efficacy. Those that are hollow in the center and large are light and float upward, clearing Lung heat to stop coughing and transform phlegm, and regulating red eyes; those that are tight, solid, and thin are heavy and descend downward, purging Large Intestine fire and removing dampness, treating dysentery while also calming the fetus.
