Dansha (Cinnabaris): Sweet in flavor, slightly cold in nature. It governs various diseases of the five Zang organs (Zang-Fu Organs) of the body, nourishes Jing-Shen (Essence and Spirit), calms Hun-Po (Ethereal Soul and Corporeal Soul), benefits Qi (Vital Energy), brightens the eyes, and kills Jing-Kui (demons) and evil ghosts. Long-term administration facilitates communication with Shen-Ming (Spiritual Intelligence) and prevents aging. It can transform into Gong (Mercury/Hydrargyrum). It is produced in mountain valleys. (The Taiping Yulan cites it with the additional characters "produced in mountain valleys." The Daguan edition writes "produced in the mountain valleys of Fuling." These characters are all in black ink in the original text. Textual research indicates that "produced in mountain valleys" is the original canonical text, while the names of prefectures and counties were added by later commentators as annotations. Therefore, "produced in mountain valleys" should be changed to white characters, while the prefecture and county names should remain in black. The following sections follow this convention.)

The Wu Pu Ben Cao states: Regarding Dansha, Shen Nong considers it sweet in flavor; the Yellow Emperor considers it bitter in flavor and toxic; Bian Que considers it bitter in flavor; Li Shi considers it greatly cold in nature. Some are produced in Wuling. There is no fixed season for collection. It can transform into Wei-Cheng Shuiyin (immature Mercury/Hydrargyrum). It is incompatible with Ci Shi (Magnetitum) and antagonistic to salty water (cited from Taiping Yulan).

The Ming Yi states: When processed into powder, it is called Zhenzhu (True Cinnabar). Its luster and color resemble Yunmu (Mica). Specimens that are easily broken are of good quality. It is produced in the mountain valleys of Fuling. There is no fixed season for collection.

Commentary: The Shuo Wen Jie Zi states: Dan refers to the red stone from the Ba and Yue regions. The character resembles a well for mining cinnabar and the shape of cinnabar itself. In ancient script, it was written as "Ri," and also as Tong, Sha, meaning water-dispersed stone. is the Shuiyin (Mercury/Hydrargyrum) transformed from Dansha. The Guan Zi, Chapter on Earth Numbers, states: Where there is Dansha on the mountain, there is Jin (Gold/Aurum) below. The Huainanzi, Training on Terrain, states: Chi Shi (Red Arrow) produces Chi Dan (Red Cinnabar) after seven hundred years; Chi Dan produces Chi after seven hundred years. Gao You comments: Chi Dan is Dansha. The Lie Xian Zhuan states: Chi Fu could prepare Shui (likely referring to a mercury preparation or elixir), refine Dan (Cinnabar), and take it with Xiao Shi (Natrii Nitras). Note: Regarding mineral and metallic medicines, when ancients stated that long-term administration lightens the body and extends life, they implied that one must practice Bi Gu (Grain Avoidance), abstain from sexual intercourse, or take the medicine for decades before effects are observed. Modern people consume these medicines along with meat and grains, often resulting in adverse effects and causing disease. Therefore, one should not doubt the validity of the ancient texts regarding these specific conditions.

Yunmu (Mica): Sweet in flavor, neutral in nature. It governs Si Ji (Dead Flesh/Necrotic Tissue) of the skin, treats Zhong Feng (Wind Strike) characterized by alternating chills and fever, and alleviates vertigo resembling motion sickness (as if on a carriage or boat). It expels Xie Qi (Pathogenic Qi), calms the five Zang organs, benefits Zi Jing (Reproductive Essence), and brightens the eyes. Long-term administration lightens the body and extends life. It is also known as Yunzhu, Yunhua, Yunying, Yunye, Yunsha, or Linshi. It is produced in mountain valleys.

The Ming Yi states: It is produced among the rocks of Mount Tai, Mount Qilu, Langya, and Mount Beiding. It is collected in the second lunar month. (This records the statements of the Ming Yi, which correspond to those of Zhang Zhongjing, Hua Yuanhua, and Wu Pu. Later compilers merged these accounts, making them indistinguishable. This inclusion serves to supplement the incompleteness of Wu Pu's book.)

Commentary: The Lie Xian Zhuan states: Fang Hui refined and consumed Yunmu. The Bao Pu Zi, Chapter on Immortal Medicines, states: There are five types of Yunmu: The type possessing all five colors but predominantly green is called Yunying, suitable for consumption in spring. The type possessing all five colors but predominantly red is called Yunzhu, suitable for consumption in summer. The type possessing all five colors but predominantly white is called Yunye, suitable for consumption in autumn. The type possessing all five colors but predominantly black is called Yunmu, suitable for consumption in winter. The type possessing only green and yellow colors is called Yunsha, suitable for consumption in late summer (Ji Xia). The type that is crystalline and pure white is called Linshi, suitable for long-term consumption throughout all four seasons. Li Shan's Annotation on Wen Xuan cites the Yi Wu Zhi: Yunmu, also known as Yunjing, does not decay even if buried underground for ten thousand years. The Shuo Wen Jie Zi does not contain the character "Lin." The Yu Pian states: Lin means thin; it is an alternative name for Yunmu.
