Bitter, cold, slightly toxic. Enters the Foot-Jueyin (Liver) Meridian. Resolves pathogenic heat, stops epistaxis, eliminates blood strangury, drives out various toxins, kills three types of parasites, breaks up masses and accumulations, and treats metal wounds. For diseases caused by internal pathogens manifesting externally, it is often effective. Combined with *Sumu* (Pterocarpus santalinus Lignum), it treats cough with purulent blood. Combined with *Shengma* (Cimicifugae Rhizoma), *Gancao* (Glycyrrhizae Radix et Rhizoma), and *Chishao* (Paeoniae Radix Rubra), it promotes the eruption of smallpox/variolous eruptions.

When combined with pure Yin medicines, it achieves the function of "Water and Fire having reached each other" (Ji Ji). As the sovereign herb combined with *Dahuang* (Rhei Radix et Rhizoma), it treats alcoholic gout. Soak in boiling water to remove the heart. To assist Yang, soak and steam with decoction of *Qizi* (Lycii Fructus). To dispel wind-damp, stir-fry with good wine. To secure essence, stir-fry with juice of *Jinyingzi* (Rosa laevigata Fructus). To regulate Kidney Qi, boil together with *Juhua* (Chrysanthemi Flos). Contraindicated for four conditions: fire hyperactivity causing essence leakage, deficiency of Yin water, difficult urination, and dry mouth and tongue. *Bajitian* (Morinda officinalis Radix) and *Suoyang* (Cynomorii Herba) warm the cold of the Kidney Meridian. *Shudi* (Rehmanniae Radix Praeparata) and *Qizi* control the heat of the Kidneys. Kidney deficiency often involves heat, while Kidney Meridian deficiency often involves cold; meridians and zang-organs differ, and water and fire must be distinguished clearly; do not misuse.
