（云母出太山山谷、齐山、庐山、及琅琊、北定山石间，今兖州云梦山及江州、淳州、
杭越间，亦有生土石间，作片成层可析，明滑光白者为上。候云气所出之处，于下掘取即获，
之根，故名云母，而云母之根，则阳起石也。）
今时用阳起石者有之，用云母者甚鲜，故但存《本经》原文，不加诠释，后凡存《本经》

气味甘平，无毒。主治黄胆，泄痢，肠癖浓血，阴蚀，下血赤白，邪气痈肿，疽痔
，恶疮，头疮疥瘙。久服补髓益气，肥健不饥，轻身延年，五色石脂，各随五色，补五脏。
（《本经》概言五色石脂，今时只用赤白二脂。赤白二脂，赤中有白，白中有赤，总名
赤石脂。不必如《别录》分为二也。始出南山之阳，及延州、潞州、吴郡山谷中，今四方皆
有。此石中之脂，如骨之髓，故揭石取之以理腻粘舌缀唇者为上。）
石脂乃石中之脂，为少阴肾脏之药。又，色赤象心，甘平属土。主治黄胆、泄痢、肠癖
浓血
者，脾土留湿，则外疸黄而内泄痢，甚则肠癖浓血。石脂得太阴之土气，故可治也。阴蚀下
血赤白，邪气痈肿、疽痔者，少阴脏寒，不得君火之阳热以相济，致阴蚀而为下血赤白，邪
气痈肿而为疽痔。石脂色赤，得少阴之火气，故可治也。恶疮、头疡、疥瘙者，少阴火热不

肾脏之水气以相滋，致火热上炎，而为恶疮之头疡疥瘙。石脂生于石中，得少阴水精之气，
故可治也，久服则脂液内生，气血充盛，故补髓益气。补髓助精也，益气助神也，精神交会
于中土，则肥健不饥，而轻身延年。《本经》概言五色石脂，故曰各随五色补五脏。
[Cloud Mother]
The flavor is sweet and neutral, non-toxic. It treats stiffness and necrosis of the skin and muscles of the body, wind-stroke with alternating cold and heat, a sensation as if dizzy in a carriage or boat, expels evil qi, calms the five zang organs, benefits kidney essence (Jing), and brightens the eyes. Long-term use makes the body light and extends longevity.
(Cloud Mother originates from the valleys of Mount Tai, Qi Mountain, Lushan, and between the rocks of Langya and Beiding Mountains. Currently, it is also found growing among earth and stones in Yunmeng Mountain in Yanzhou, Jiangzhou, Chunzhou, and between Hangzhou and Yuezhou. It forms in layers that can be split into sheets; those that are transparent, smooth, and white are of superior quality. Observe where cloud vapor emerges, dig below to obtain it. Because it is the root of clouds, it is named Cloud Mother; and the root of Cloud Mother is Yangqi Stone.)
[Red Kaolin]
The flavor is sweet and neutral, non-toxic. It treats jaundice, diarrhea and dysentery, purulent blood in the stool, erosion of the genitals, bleeding from the lower orifice with red and white discharge, evil qi-induced abscesses and swellings, carbuncles and hemorrhoids, malignant sores, head sores, and scabies/itching. Long-term use replenishes marrow, boosts qi, makes the body plump and strong without hunger, lightens the body, and extends longevity. The five-colored kaolins, each corresponding to their respective colors, tonify the five zang organs respectively.
(The *Shennong Bencao Jing* generally mentions five-colored kaolins, but currently only red and white kaolins are used. Red kaolin contains white streaks, and white kaolin contains red streaks; collectively they are named Red Kaolin. There is no need to divide them into two types as in the *Mingyi Bielu*. It originally originated from the south of Mount Nan, as well as the valleys of Yanzhou, Luzhou, and Wujun; now it is available everywhere. This lipid-like substance within the stone is like the marrow within bones; therefore, when extracted from the stone, the one that is fine, sticky to the tongue, and adheres to the lips is of superior quality.)
Kaolin is the lipid within the stone and is a medicine for the Shaoyin Kidney channel. Furthermore, its red color corresponds to the Heart, and its sweet and neutral nature belongs to Earth. It treats jaundice, diarrhea/dysentery, and purulent bloody stools because dampness retained in Spleen Earth causes external yellowing (jaundice) and internal diarrhea/dysentery, which in severe cases leads to purulent bloody stools in the intestines. Kaolin obtains the Earth qi of Taiyin Spleen, thus it can treat these conditions. It treats genital erosion, lower bleeding with red and white discharge, and evil qi-induced abscesses/carbuncles/hemorrhoids because Cold in the Shaoyin organ fails to receive the warming yang heat of Minister Fire, leading to genital erosion and lower bleeding with red and white discharge, and evil qi stagnation causing abscesses manifesting as carbuncles and hemorrhoids. Kaolin is red and obtains the Fire qi of Shaoyin Heart, thus it can treat these conditions. It treats malignant sores, head sores, and scabies/itching because Shaoyin Fire heat fails to receive nourishment from Kidney Water, leading to fire heat flaring upward, resulting in malignant sores, head sores, and scabies/itching. Kaolin grows within stones and obtains the Essence qi of Shaoyin Kidney Water, thus it can treat these conditions. Long-term use generates internal lipids and fills the blood and qi, thereby replenishing marrow and boosting qi. Replenishing marrow assists Essence; boosting qi assists Spirit. When Spirit and Essence intersect in the Central Earth, the body becomes plump and strong without hunger, light, and long-lived. Since the *Shennong Bencao Jing* generally mentions five-colored kaolins, it states that they tonify the five zang organs according to their respective colors.
