[Names] Shitingzhi (Stone Paraffin, from *Tu Jing* [Illustrated Classic]), Shi Ludan (Stone Sulfur Cinnabar, named by Tao Hongjing), Shizhizhi.
[Collection and Explanation] *Bie Lu* states: The texture resembles Shiqi, growing among mountain rocks. Pu Yue states: It grows in the valleys of Qiandao.
Li Shizhen states: This is simply sulfur that is reddish in color, named Shitingzhi. However, people in recent times generally refer to sulfur as Shitingzhi, which shows a lack of proper examination. According to *Baopuzi*, Shi Ludan is the red essence of stones, belonging to the category of stone sulfur. It seeps and overflows between banks; the moist parts can be formed into pills for oral administration, while the hard, consolidated parts can be taken as powder. It is found in the Five Great Mountains, with Jishan having the most abundance. Xu You and Chao Fu consumed it, which refers to Shizhizhi.
[Flavor and Properties] Bitter, warm, non-toxic.
[Indications] Leukorrhea in women, hemostasis. Lightens the body and prolongs longevity (*Bie Lu*). Strengthens yang, dispels cold, treats sores, and kills parasites; its efficacy is similar to that of sulfur (Li Shizhen).
[Attached Prescriptions] Two new prescriptions. Red nose pain: Use purple Shitingzhi; red is secondary; do not use yellow. Grind into powder, mix with cold water, and apply externally. Roots will be eliminated within half a month (*Shengji Lu*). Rheumatic gout: Raw Shitingzhi 1 liang, raw Chuan Wutou (Aconitum carmichaelii) 1 liang, Wumingyi (Hematite) 2 liang.
