青，
大者如拳如卵，小者如豆粒，或如杨梅。其色青，其中皆空，故曰空青。内有浆汁，为治目

（白石英始出华阴山谷及太山，今寿阳、泽州、虢州、洛州山中俱有。大如指，长二三
寸，
六面如削，白莹如玉而有光，长五六寸，益佳。或问天地开辟，草木始生，后人分移莳植。
故他处亦有。今土中所生之石，亦有始生，与他处之分何耶？愚曰∶草木金石虫鱼皆为物类
，始生者开辟之初，物之先见也。他处者，生育之广，物之繁盛也。天气从东南而西北，则
草木始生东南者，未始不生西北，西北虽生，不如东南之力也。地气从西北而东南，则金石
之始生西北者，未始不生东南，东南虽生，不如西北之力也。而岂莳植移徒之谓哉。若以草
木土石而异视之，何所见之不大也。）
紫白石英，品类相同，主治亦不甚远。紫为木火之色，气味甘温，故治心腹、肾脏之寒。
白
(Kongqing, Azurite) Its flavor is sweet and sour, its nature is cold, and it is non-toxic. It treats blindness (Qingmang), deafness, brightens the eyes, unblocks the nine orifices, unifies the blood vessels, nourishes the spirit, and benefits Liver Qi. Long-term consumption makes the body light and prolongs life.
(Azurite, also known as Yangmei Qing, originally originated from the valleys of Yizhou and Yuejun Mountain. Currently, in places like Weilan and Xuanzi where copper is mined, Kongqing is generated by the fumes of copper essence. Large pieces are the size of a fist or an egg, small ones are bean-sized or like bayberries. Its color is green, and its interior is hollow, hence the name Kongqing. It contains a liquid pulp, which is a divine medicine for treating eye diseases. If it is not hollow and lacks pulp, it is called Baiqing (White Azurite). Currently, practitioners apply medicine onto copper objects, scrape off the generated green substance, and fake it as Kongqing; genuine ones are hard to obtain.)
(Zishi, Purple Fluorite) Its flavor is sweet, its nature is warm, and it is non-toxic. It treats cough and rebellious Qi in the heart and abdomen, expels pathogenic factors, tonifies deficiencies, and treats women's infertility caused by Wind-Cold in the uterus, resulting in ten years without children. Long-term consumption warms the Middle Jiao, makes the body light, and prolongs life.
(Purple Fluorite originally originated from the valleys of Mount Tai. Currently, it is found in the mountains of Kuaiji, Zhuji, Wucheng, Yongjia, Yangshan, and Dongguan, but those from Mount Tai are the best. Its color is pale purple, its texture is crystal clear, it has five edges regardless of size, and both ends resemble arrowheads.)
(Baiqing, White Fluorite) Its flavor is sweet, its nature is slightly warm, and it is non-toxic. It treats Xiao Ke (Wasting-Thirst syndrome), impotence and insufficiency, cough and rebellious Qi, chronic cold in the chest and diaphragm, boosts Qi, and dispels Wind-Damp Bi syndrome. Long-term consumption makes the body light and prolongs life.
(White Fluorite originally originated from the valleys of Huayin and Mount Tai. Currently, it is found in the mountains of Shouyang, Zezhou, Guozhou, and Luozhou. Large pieces are finger-sized, two to three cun long, with six flat faces like cut jade, white and lustrous; pieces five to six cun long are better. Some ask: When Heaven and Earth were created, plants began to grow, and later people transplanted them, so they exist elsewhere. Do stones growing in the soil now differ from those elsewhere? I say: Plants, minerals, insects, and fish all belong to the category of things. Naturally occurring ones represent the first appearance of things at the beginning of creation; those found elsewhere represent the broad scope of generation and the prosperity of things. Heavenly Qi flows from Southeast to Northwest; thus, while plants begin to grow in the Southeast, they do not fail to grow in the Northwest, though their vitality there is inferior to that in the Southeast. Earthly Qi flows from Northwest to Southeast; thus, while minerals begin to form in the Northwest, they do not fail to form in the Southeast, though their quality there is inferior to that in the Northwest. How could this be merely explained by transplantation and movement? To view plants, wood, earth, and stones differently would be a limited perspective.)
Purple Fluorite and White Fluorite share the same category and have similar therapeutic indications. Purple corresponds to the colors of Wood and Fire, and with its sweet and warm flavor, it treats Cold in the Heart, Abdomen, Kidney, and Bladder. White...
