产于四川龙安府石泉县石纽乡，以颜色红得像血一样的为佳。《四川通志》记载：出产于石泉禹穴下方，石头表皮像被血染过一样，气味腥臭，用滚水冲泡饮用，能够催生。治疗难产。
《柑园小识》记载：桃花盐产自泽旺，每年春深时颜色红如桃花，到了夏天红色逐渐减退，秋冬季节颜色变白，到了春天又变红。胃痛患者用它来治疗胃痛，将盐熨烫患处即可立即止痛。
《池北偶谈》记载：高阳百姓家一个十多岁的儿子，忽然手臂上长出一个陈旧的肿瘤，疼痛和瘙痒难以忍受，医生都不清楚是什么病症。一天突然溃破，里面有一个圆形的卵状物掉落出来，随即化为石头，刘工部用一个金子的价格买下了它，用来治疗膈症效果神奇。治疗痞结膈症。
《唐书》记载：仆骨国东境的康于河，折断松树投入河中，立刻化为石头，颜色很好，称为康于石。《录异记》记载：婺州永康县的山亭中有一棵枯死的松树，因为折断它，不小心掉入水中化为石头，取还没有完全化成的部分在水中试验，也随之化开，所化成的部分枝干如同树皮与松木无异，只是质地坚硬强劲。《博物志》说：松树本由石气产生，石头裂缝受沙即长出松树，松树生长三千年后又化为石头。《舆地纪胜》记载：宋建炎年间，遂宁府转运使衙门后花园有松石，外表还是松树的样子，而内部已化为石头。另外重庆府永川县有石松坪，有松花石，石头质地而有松树的纹理，有的长达二三尺，大的可以合抱，然而不过相隔几座山才有，俗称雷烧松。《神仙传》说，松树三千年应当化为石头。《张绿猗涂说》记载：松花石有黄色和紫色两种颜色，质地纹理非常细腻，皮上有水波纹，或者松树皮纹，也有节晕纹的，天台山间有出产。西北地区也出产，是年久折断的松树落入涧水，得到地气变化而成石头。并且还有没有完全变化的，还带有松质部分的，入药适宜使用完全化开的。服用它能让人忘却情感、断绝杂念。治疗相思症，凡是男女有所思慕而不能如愿的，服用它，就会断绝念头不再想念。
赵学敏按语：松化石是有情之物化为无情之物，是阳极反阴的现象。男女爱慕，结想成病，导致君火（心火）和相火（肾火）虚性磨动妄行，销铄耗损真阴，魂狂魄越，神不守舍。不用这种反向折转的方法使其回归平和不可，正是利用其贞静凝重的性质来释解妄缘。李时珍《本草纲目》石部“不灰木”后附录松石说：松树长久所化，不入药用，这大概是没有深入知晓其中的奥妙罢了。
Produced in Shiniu Township, Shiquan County, Long'an Prefecture, Sichuan Province, those with a red color resembling blood are considered superior. *Sichuan Tongzhi* records: It is found below the Yu Cave in Shiquan; the stone's skin appears as if dyed with blood, has a fishy odor, and when brewed and drunk with boiling water, it can induce labor. It treats difficult childbirth.
*Ganyuan Xiaoshi* records: Taohua Yan (Peach Blossom Salt) is produced in Zewang. In late spring, its color is red like peach blossoms; by summer, the redness gradually fades; in autumn and winter, it turns white; and in spring, it becomes red again. For patients with stomach pain, applying this salt via hot compressing stops the pain immediately.
*Chibei Outan* records: A son of a commoner in Gaoyang, aged over ten, suddenly developed an old tumor on his arm, causing unbearable pain and itching; physicians could not identify the condition. One day, it suddenly ulcerated, and a round, egg-like object fell out, which subsequently turned into a stone. Liu Gongbu purchased it for one tael of gold and used it to treat Gezheng (diaphragmatic obstruction) with miraculous effect. It treats Pi Jie Gezheng (痞结膈症 - obstructive diaphragmatic disease).
*Tangshu* records: In the eastern territory of Pugu, at Kangyu River, pine trees broken off and thrown into the water instantly turned into stone. The color was excellent, and it was called Kangyu Shi (康于石). *Luyiji* records: In a mountain pavilion in Yongkang County, Wuzhou, there was a dead pine tree. While breaking it, it accidentally fell into the water and turned into stone. Testing untransformed parts in water showed they also transformed; the resulting stone retained the appearance of bark and pine wood but was hard and strong. *Bowuzhi* states: Pine trees originate from stone qi; when stone cracks receive sand, pines grow; after three thousand years, pines transform back into stone. *Yudi Jisheng* records: During the Jianyan era of the Song Dynasty, behind the residence of the Transport Commissioner in Suining Prefecture, there was a "pine stone," which looked like a pine tree externally but was stone internally. Additionally, in Yongchuan County, Chongqing Prefecture, there was Stone Pine Flat, featuring Songhua Shi (松花石 - pine-flower stone), which had a stone texture with pine grain patterns. Some were two or three chi long, large enough to embrace, though found only in mountains within sight of each other, commonly called Lei Shao Song (Thunder-burnt Pine). *Shenxian Zhuan* states that pines transform into stone after three thousand years. *Zhang Lvyi Tusuo* records: Songhua Shi comes in yellow and purple colors, with fine texture. The surface has water-like patterns, pine bark patterns, or knot-ring patterns; it is found in Tiantai Mountain. It is also produced in the northwest, formed when old broken pines fall into stream waters and transform due to earth qi. Some transformations are incomplete, retaining pine substance; for medicinal use, fully transformed stones are preferred. Taking it makes people forget emotions and cease distracting thoughts. It treats Xiangsi Zheng (相思症 - lovesickness). For men and women whose desires are unfulfilled, taking it causes them to abandon their obsessive thoughts.
Zhao Xuemin notes: Songhua Shi represents the transformation of sentient beings into insentient matter, symbolizing the reversal from extreme Yang to Yin. When men and women love and obsess, forming illness, it leads to the deficiency and erratic movement of Junhuo (君火 - Minister Fire/Heart Fire) and Xianghuo (相火 - Official Fire/Kidney Fire), consuming true Yin, causing wild soul and scattered spirit, with the Shen (Spirit) failing to reside in its house. Without using this method of counteracting and turning back to restore peace, it cannot be cured. Its value lies precisely in its chaste and condensed nature, which dissolves delusional attachments. Li Shizhen, in the appendix to "Buhui Mu" (Not-Gray Wood) in the Stone section of *Bencao Gangmu*, stated that pines transformed over long periods are not used medicinally; this likely reflects a lack of deep understanding of its profound mysteries.
