《病源论》云∶肾（时忍反，下同）主腰脚，服石，热归于肾。若将适失度，发动石热，
气乘腰脚，石势与血气相击，故脚热肿痛也。其状脚烦热而腰痛也。
皇甫谧云∶或脚疼欲折，坐下温，宜常坐寒床，以冷水洗起行。又云∶或腰痛欲折，坐
衣浓体温，以冷水洗，冷石熨之。
皇甫谧云∶或百节酸（丝官反，下同）痛，坐卧下大浓，又入温被中，又衣温不脱故也，
卧下当极薄大要也。被当单布，不着绵衣，亦当薄且垢，故勿着新衣，宜着故絮也。虽冬寒
当常KT 头受风，以冷石熨，衣带初不得系也。若犯此酸闷者，促入冷水浴，勿忍病而畏
浴也。
《极要方》云∶服乳石不得将慎，冲热失食，憎寒头痛，百节酸（素官反，疼痛也）疼。
口唇干焦（即消反）舌卷方∶
知母（八分） 石膏（十三分，碎） 升麻（六两） 通草（八分） 硝石（八分，汤
成下） 竹青皮（六分） 露蜂房（二枚，炙）
切，以水二大升，煎取九合，食后分温三服。
《短剧方》云∶解散二物麻子豉汤治人虚劳，下焦有热，骨节疼烦，肌急内圯（备美反，
毁也。又岸崩貌），小便不利，大行数少，吸吸口燥。少气折石热方∶
豉（二升） 麻子〔五合，擂（力推反，研物也）取仁〕
凡二物，研麻子仁，以水四升，煮取一升半，分服五合，日三便愈，神验。
《诸病源候论》说：肾（“时忍”反切，下同）主管腰部和脚部，服用石药后，热邪归于肾脏。如果调养失当，引发石热，热气侵袭腰脚，石药的势能与血气相互搏击，所以出现脚部发热、肿胀疼痛的症状。其表现为脚部烦热且腰部疼痛。
皇甫谧说：有的患者脚痛欲断，坐下时感觉温暖适宜，应当常坐凉床，用冷水清洗后起身行走。又说：有的患者腰痛欲断，坐着时衣服紧贴身体感到温热，应用冷水清洗，并用冷石熨贴患处。
皇甫谧说：有的患者全身关节酸痛（“丝官”反切，下同），躺卧时觉得被褥过于厚重，又进入温暖的被窝中，加上穿着温热的衣服不脱下所致。躺卧时应当极其单薄宽大。被子应使用单层布，不要穿棉衣，衣物也应薄且陈旧，因此不要穿新衣，宜穿旧棉絮做的衣服。即使在冬天寒冷时，也应当经常让头部受风，用冷石熨贴，衣带起初不得系紧。如果因此出现酸闷不适，应立即进入冷水浴，不要因为害怕洗澡而忍受病痛。
《极要方》说：服用乳石后如果不注意调护，导致冲热失食，会出现怕冷头痛，全身关节酸痛（“素官”反切，意为疼痛）。口唇干燥焦裂。舌卷缩方：
知母（八分） 石膏（十三分，捣碎） 升麻（六两） 通草（八分） 硝石（八分，汤剂煎成时下入） 竹青皮（六分） 露蜂房（二枚，炙烤）
切碎，用水两大升，煎取九合，饭后分三次温服。
《短剧方》说：解散二物麻子豉汤治疗虚劳，下焦有热，骨节疼痛烦躁，肌肉拘急内陷（“备美”反切，意为毁坏。又指岸边崩塌的样子），小便不利，大便次数多但量少，呼吸急促口干。少气折除石热方：
豆豉（二升） 麻子仁（五合，研磨取仁）
以上两味药，研磨麻子仁，用水四升，煮取一升半，每次分服五合，每日三次即可痊愈，效果神奇。
The *Zhubing Yuanhou Lun* (Treatise on the Pathogenesis and Symptoms of All Diseases) states: The Kidney governs the waist and legs. After taking mineral drugs (Shiyao), heat accumulates in the Kidney. If care is improper, triggering the "stone heat," the qi attacks the waist and legs. The momentum of the stone drug clashes with the blood and qi, resulting in hot, swollen, and painful feet. The presentation involves irritative heat in the feet and lower back pain.
Huangfu Mi stated: In some cases, foot pain is so severe it feels as if breaking; sitting down feels warm and comfortable. One should frequently sit on a cool bed and wash with cold water before standing up to walk. He also stated: In some cases, lower back pain is so severe it feels as if breaking; while sitting, clothing adheres to the body feeling warm. One should wash with cold water and apply cold stones for moxibustion-like warming (ironing/pressing).
Huangfu Mi stated: In some cases, all joints ache (pronunciation note: same as below). Lying or sitting feels too heavy due to thick bedding, entering warm quilts, and wearing warm clothes without removing them. When lying down, one should use extremely thin and large blankets. The quilt should be single-layer cloth; do not wear cotton-padded clothes. Clothes should also be thin and old; therefore, do not wear new clothes, but rather wear old wadding. Even in winter cold, one should frequently expose the head to wind and apply cold stones for pressing. Initially, the belt should not be tied tightly. If one suffers from acid-numbness and stuffiness under these conditions, immediately enter a cold water bath; do not endure the illness out of fear of bathing.
The *Jiyao Fang* (Extremely Essential Prescriptions) states: After taking milk stone (Rushi), if one fails to take proper precautions, leading to rushing heat and loss of appetite, one may experience aversion to cold, headache, and joint aches (pronunciation note: meaning pain). Dry and scorched lips. Tongue curling formula:

The *Duanju Fang* (Short Drama Prescriptions) states: Sanjie Erwu Mazhichi Tang (Dispersing Two-Ingredient Hemp Seed and Fermented Soybean Decoction) treats deficiency consumption (Xulao) with heat in the Lower Jiao, painful and irritable bone joints, muscle tension and internal collapse (pronunciation note: meaning destruction; also describes bank collapse), difficult urination, frequent defecation with small volume, rapid breathing, and dry mouth. Shaoqi Zeshi Re Fang (Minor Qi Reducing Stone Heat Formula):
* **Chi** (Fermented Soybean, 2 sheng)
* **Mazi Ren** (Cannabis Semen, 5 he, pounded to extract the kernel)
Take the above two ingredients, pound the hemp seed kernels, add four sheng of water, boil to obtain one and a half sheng. Divide into five he doses, taken three times daily until cured. It is miraculous and effective.
