《服石论》中说：八仙传说，绛雪能治疗各种疾病，八公传授给淮南王的绛雪方就是此方。八公说：“你得到这个方子，就不会短命暴死，其神妙无比。”大和先生将其命名为“通中散”，非常重视此方，每次只服用一合（容量单位）并进献上去。又经常劝人服用它。世间有人窃取此方自行配制，俗称为“红雪”。但大家都未能掌握关键诀窍，又没有经过师父的口传心授，有的药材种类短缺，分量参差不齐，或者调和不当，煎煮炼制过度，所以用来治病大多没有效果。现在详细记载药物数量、分量以及四季配制方法和口诀要点，所主治的病状、服法、禁忌都详细列在下面，配制的人，不可随意加减药味，以免误害后人。煎煮炼制过度，会损害药效。这些都是依据经典方剂并遵循师父口诀，既避免了短命暴死的忧虑，确实是保全生命的至关重要之法，应当珍视保密，千万不要轻易泄露。不是同道中人，不要妄加传播。所主治的病症如下：治疗一切丹石发热（服用丹药后产生的热症），天行时行（流行性传染病），温疟，疫疾（瘟疫性疾病），痈疽发背（背部发生的痈疽），上气咳嗽，香港脚风毒（脚气病伴风毒症状），肺气肺痈，涕唾涎粘，头风旋愤（头痛眩晕），面目浮肿，心胸伏热，骨热劳热，口干口臭，热风冲上，目赤热痛，四肢瘫痪，心忪惊狂，恍惚谬语，骨节烦疼，皮肤热疮，昏沉多睡，赤白热痢，大小便不通，解药毒、食毒、酒毒。
以上患有前述病症的人，用水送服此药。
诸气结聚，心腹胀满，宿食不消，痰水积聚，醋咽呕吐，产后血运（产后血晕），中风闷绝，产后热病，坠堕畜血（跌打损伤导致的瘀血）。
以上患有前述病症的人，用酒送服此药。
又说：如果病情与此方相当，取一匙绛雪，用刚打来的冷水二大合及蜜水，也可以加入水中，使其溶解后一次性服用。
现在考证：《外台秘要》中说：凡是服用丹药之后，如果觉得身体大热，可以服用紫雪或金石凌或绛雪或白雪等，只需半大升，取瓷碗研磨成粉，一大两，在香汤沐浴后，一次性服用。等等。
另外，现在的人根据自身体质的强弱，有的服用三四两，有的服用五六两，研细后空腹服用。此外，本方记载了制作日子的忌讳，但没有服药时间的禁忌，而药中含有朱砂、甘草、槐花，需要忌食血类食物、海藻、猪肉。又有私人笔记记载：妇女怀孕，不得服用此药。
The *Treatise on Taking Minerals* states: According to the legend of the Eight Immortals, Jiangxue (Crimson Snow) can treat various diseases. The Jiangxue formula taught by Master Baogong to Prince Huainan is precisely this one. Master Baogong said, "If you obtain this formula, you will not suffer premature or violent death; its efficacy is incomparably miraculous." Mr. Dahe named it Tongzhong San (Universal Middle Powder) and held this formula in high regard, administering only one he (a unit of volume) at a time and presenting it as tribute. He also frequently advised others to take it. Some people in the world stole this formula and prepared it themselves, commonly calling it Hongxue (Red Snow). However, none of them grasped the essential techniques, nor did they receive oral transmission from a master. Some lacked certain medicinal ingredients, the dosages were inconsistent, or the mixing was improper, and the decoction and refining process was excessive. Consequently, using it to treat illnesses often proved ineffective. Herein, the quantities and dosages of the herbs, along with the methods for preparation in the four seasons and the key oral instructions, are fully recorded. The main indications, administration methods, and contraindications are detailed below. Those preparing it must not arbitrarily add or subtract ingredients, so as not to harm future users. Excessive decoction and refining will impair the medicinal power. These formulations are based on classical prescriptions and follow the master's oral teachings, thereby avoiding the worry of premature death and truly representing the most crucial method for preserving life. They should be treasured and kept secret; do not disclose them lightly. Do not transmit them recklessly to those who are not initiated. The conditions treated are as follows: It treats all fevers caused by Dan Shi (mineral pills), Tian Xing Shi Xing (epidemic diseases), Wen Nue (warm malaria), Yi Ji (plague-like diseases), Yong Ju Fa Bei (carbuncles and sores on the back), Shang Qi Ke Sou (rebellious qi and cough), Xiang Gang Jiao Feng Du (Hong Kong foot wind toxicity, i.e., beriberi with wind-toxicity symptoms), Fei Qi Fei Yong (lung qi stagnation and lung abscess), sticky nasal discharge and saliva, Tou Feng Xuan Fen (head wind with dizziness and irritability), facial and eye edema, Fu Re in the chest and heart, Gu Re Lao Re (bone fever and consumptive fever), dry mouth and bad breath, Re Feng Chong Shang (wind-heat rushing upward), red and painful eyes, paralysis of the four limbs, Xin Song Jing Kuang (palpitations and manic delirium), confusion and erroneous speech, painful joints, hot skin sores, lethargy and excessive sleep, Chi Bai Re Li (dysentery with red and white stools), obstruction of urination and defecation, and antidotes for drug, food, and alcohol poisoning.
For those suffering from the aforementioned conditions, administer with water.
For Qi Jie Ju (stagnation of qi accumulation), Xin Zhang Man Fu (chest and abdominal fullness), Su Shi Bu Xiao (undigested food retention), Tan Shui Ji Ju (accumulation of phlegm and fluid), Cu Yan Ou Tu (vomiting due to sour regurgitation), Chan Hou Xue Yun (postpartum blood syncope), Zhong Feng Men Jue (stroke with coma), Chan Hou Re Bing (postpartum febrile disease), Zhui Duo Xu Xue (traumatic blood stasis from falls),
For those suffering from the aforementioned conditions, administer with wine.
It is also stated: If the condition matches the indication, take one spoonful of Jiangxue, dissolve it in two large he of fresh cold water mixed with honey water, or simply add it to water, allow it to dissolve, and take it in one dose.
Currently, according to the *Wai Tai Mi Yao*: After taking mineral pills, if one feels intense heat, one may take Zi Xue (Purple Snow), Jin Shi Ling (Mineral Ice), Jiangxue (Crimson Snow), or Bai Xue (White Snow). Take half a da sheng (large volume unit), grind one da liang (large weight unit) into powder using a porcelain mortar, and take it in one dose after bathing in fragrant water. And so on.
Furthermore, contemporary individuals adjust the dosage according to their physical strength, taking either three or four liang, or five or six liang, finely ground and taken on an empty stomach. Additionally, while this formula specifies taboos for the days of preparation, it does not specify taboos for the time of administration. However, since the formula contains Cinnabar (Zhusha), Licorice Root (Gancao), and Sophora Flower (Huaihua), one should avoid consuming blood products, Kelp (Haizao), and pork. Private notes also record that pregnant women must not take this medicine.
