Chishizhi (Red Halloysite):
Heavy and astringent, secures the Large Intestine and Small Intestine.
Sweet, warm, sour, and astringent. Capable of absorbing dampness, stopping bleeding, and securing the Lower Jiao (Lower Burner). (*Bencao Jingshu* states: For deficiency collapse of the Large and Small Intestines after purgation, only astringent agents can secure them; other astringent drugs are light and floating and cannot reach the Lower Jiao, whereas Chishizhi is heavy and astringent, entering directly into the Yin aspect of the Lower Jiao, thus making it an essential drug for chronic dysentery and diarrhea.) Treats intestinal wind, diarrhea, and dysentery. Treats metrorrhagia (uterine bleeding), leukorrhea, and spermatorrhea. Treats carbuncles, hemorrhoids, and ulcers, promoting wound closure and tissue regeneration, inducing labor, and expelling the placenta. (*Bencao Jingshu* states: It can remove evil blood; when evil blood transforms, the uterus is unobstructed. Li Dongyuan said: For retained placenta, astringent agents can induce its expulsion; furthermore, it secures the stomach and intestines with its converging ability to expel the placenta without the harsh purgative action.) Fine and delicate, enters the Qi aspect. (The five-colored Shizhis enter their respective Zang organs respectively.) Grind into powder. (Some occur in lumps.) Levigate with water.
Incompatible with Yuanhua (Genkwa Flos). Hostile to Dahuang (Rhei Radix et Rhizoma) and Songzhi (Pini Resina). (For menorrhagia, equal parts of Chishizhi and Poguozhi (Psoraleae Fructus) ground into powder, taken with rice water, 2 qian.)
Yuyuliang (Limonitum):
Heavy and astringent, secures the Lower Jiao.
Sweet, neutral, and astringent. A heavy agent for the Blood aspect of the Hand-Yangming (Large Intestine, Stomach) meridians. Treats cough with counterflow qi, dysentery. Treats blood obstruction (masses), metrorrhagia. Secures the Lower Jiao. (Li Xianzhi's *Huoren Shuku* states: Diseases of the Lower Jiao are difficult to diagnose and treat; one must use Yuliang and Chishizhi.) Also induces labor. Yellow powder from stones. Grows in pools and marshes. Those without sand grains are superior. Processing methods are the same as above. (For scars on the body and face, mix with Banxia (Pinelliae Rhizoma) powder and egg yolk, apply externally; first wipe the area until red, avoid wind and sun for thirty days, effective.)
Luganshi (Calamina):
Dries dampness, treats eye diseases.
Sweet, warm. A herb for the Yangming Stomach meridian. Receives the Qi of gold and silver. Metal overcomes Wood; dryness overcomes dampness. Thus, it stops bleeding, reduces swelling, absorbs dampness, resolves phlegm, eliminates ulceration, reduces redness, removes nebula, and is an essential drug for eye diseases. (Equal parts of Luganshi, Haopiaoxiao (Sepiae Endoconcha), and Pengsha (Borisov Borax) ground into fine powder, used to instill into eyes for various eye diseases, very effective; adding Zhusha (Cinnabar) 5 qian makes the property non-sticky.) Produced in gold and silver mines. It is the sprout of gold and silver. Shape like sheep brain, loose like Shizhi. Can turn red copper yellow. (Modern brass is all made by this method.) Red color. Quench seven times in child's urine, grind into powder, levigate with water. (For chancres and genital sores, quench Luganshi five times in vinegar, 1 liang, mixed with Ercha (Catechu) powder 3 qian, applied with sesame oil.)
