Taohua Shi (Peach Blossom Stone)
Sweet in flavor, warm in nature, non-toxic. Primarily treats coldness in the large intestine causing dysentery with pus and blood. Long-term consumption causes muscle warmth and increases appetite.
The *Tang Bencao* commentary states: It originates from Zhongshan County in Shenzhou. It resembles Chishizhi (Red Kaolin), but the genuine product is identified by not sticking to the tongue when licked. (Originally attached to the preceding text.) Ministers Yuxi et al., according to the *Shu Bencao*, state: It makes one plump, radiant, and able to eat well. The *Nanhai Yaopu* records: Its appearance is also similar to Zhiyingshi (Fluorite), like peach blossoms; it is moist, lustrous, and heavy, which is what people find delightful.
The *Tujing* records: Taohua Shi is not listed in the *Benjing* regarding its origin. The commentary notes it comes from Zhongshan County in Shenzhou. Currently, it is also found in Xinzhou. Its block shape resembles Chishizhi (Red Kaolin) and Zhiyingshi (Fluorite). Its color resembles peach blossoms; it is lustrous, smooth, and heavy. The best quality is that which does not stick to the tongue when licked. There is no fixed time for harvesting. Tao Hongjing explained Chishizhi (Red Kaolin): Those used from Yiyang resemble pig brain, with a fresh red color that is lovely. Su Gong believed this was incorrect; it is actually Taohua Shi. Long-term use makes people fat. Locals also use it to treat dysentery; thus, its functions are not far apart.
The *Yanyi* states: Taohua Shi has two grades: red and white. Some have a red base with pale white spots, resembling peach blossom petals; others have a pale white base with pale red spots, resembling peach blossom petals. People often carve and grind them into utensils. Nowadays, few people consume or ingest them.

Guangming Yan (Bright Salt)
Salty and sweet in flavor, neutral in nature, non-toxic. Primarily treats various wind syndromes of the head and face, red and painful eyes, and excessive eye discharge and tearing. It is produced below the salt pools of Wuyuan in Yanzhou, mined by chiseling. The larger pieces are as big as a sheng (a unit of volume), all square, bright, and transparent. Also known as Shiyen (Stone Salt). (Originally attached to the preceding text.)
Ministers Yuxi et al., according to the *Shu Bencao* commentary, state: It is also called Shengshi (Holy Stone).

Shichuang (Stone Bed)
Sweet in flavor, warm in nature, non-toxic. Taken after soaking in wine. It shares the name Ruchuang (Milk Bed) with Yinnie. It is also called Nishi. The *Tang Bencao* commentary states: Tao Hongjing believed Konggongnie was Ruchuang, which is incorrect. The two types of Nie are located above, while Chuang and Hua are below. Although their nature and form are the same, their positions differ. Stalactite water condenses and accumulates downward, growing like bamboo shoots, gradually lengthening. Over time, it connects with the upper stalactites to form pillars. It is produced in Zhongru Tang (Stalactite Halls). There is no fixed time for harvesting. (Originally attached to the preceding text.) Ministers Yuxi et al., according to Ri Huazi, state: Shisun (Stone Bamboo Shoot) is the part where Stone Milk drips and condenses downward, growing longer. It has the same efficacy as Shihua (Stone Flower) and is also named Shichuang (Stone Bed).
