味咸，性微温。有小毒。用于煮水洗澡，可去除风瘙癣（皮肤瘙痒、疥癣）。饮用一合（约20毫升），可催吐并排出体内积滞的食物，缓解头部胀满。
又名地浆。能泻热解毒。
味甘，性寒。治疗因冷热失调引起的泄泻和痢疾，以及赤白痢。治疗腹内热毒引起的绞痛。解除各种鱼肉、蔬菜水果、药物及各类菌类中毒。（“菌”音同“郡”，生长在腐朽的木头及潮湿地面上，也称作“蕈”，枫树上的菌类，食用后令人发笑不止，服用此物即可解毒。）以及虫蜞进入腹部。（误食马蝗蜞，在腹中产卵，用此物使其排出。）中暑突然死亡者。（取道路旁被太阳晒热的土围绕肚脐，让人小便其中，仍用热土和大蒜按等量捣成粉末，去渣，灌服即可救活。《卫生宝鉴》说：中暑霍乱，是由于暑热内伤，七情迷乱所致，阴气静则神藏，躁动则消亡，非至阴之气不能治愈。坤代表阴，地属于阴，土称为静顺，地浆制作于墙根阴影下的坑中，是阴中之阴，能够泻除阳中之阳。）挖掘黄土地做成坑，深三尺。将新汲取的水倒入搅浑。片刻后，取上层清水使用。（食用黄颡鱼时若误犯荆芥，会危害人体，服用地浆可解其毒。）
宣通，助长阳气。
助长阳气，疏通经络。（汪颖说：热水必须经过一百次沸腾才好，如果只煮沸一半，饮用反而损伤元气，导致胀气。宗曰：热水能疏通经络，患有风冷气痹的人，用热水淋脚至膝盖以上，严密覆盖以取周身出汗，然而另有药物，只是借助阳气来运行罢了。四季突发泄泻痢疾，四肢及脐腹部寒冷，坐在深汤盆中，浸泡至腹部以上，频繁进行，生阳气的药物，没有比这更快的了。虚寒体质的人刚坐进汤中必定颤抖，仍需经常派人守候。张从正说：凡是受风寒或饮食酒食所伤，初起无药时，便饮太和汤一碗左右，或者酸醋汁也可以，用手揉肚子，感觉恍惚时，再饮再揉，直到无法容纳，探喉催吐，出汗就好了。李时珍说：张仲景治疗心下痞满，按之柔软，关上脉浮，用大黄黄连泻心汤，用麻沸汤煎煮，是取其气味轻薄而宣泄虚热。患风疾数年，挖坑让人坐在坑内，解开衣服，用热水淋浇良久，用竹席覆盖，出汗即愈，这也是疏通经络的方法。李时珍常推演此意，治疗寒湿，加艾叶煎汤；治疗风虚，加五枝或五加煎汤淋洗，觉得效果更快。庵曰：感冒风寒，用热水澡浴，也是发散的一种方法，所以《内经》也有可用汤熨、可浴，以及按摩沐浴的记载。《备急方》治疗心腹突然胀痛欲死，煮热水浸泡手足，冷了即更换。）又名太和汤。又名麻沸汤。（蛇缠绕不解开，用热水淋浇，即脱落；忤恶突然死亡，用铜瓦器盛装热水，隔着衣服熨烫腹部，冷了即更换。）
Salty, slightly warm. Slightly toxic. Used for bathing in boiled water to remove wind-induced pruritus and tinea (skin itching and fungal infections). Drinking one he (approx. 20 ml) induces vomiting and purgation of retained food, relieving cranial distension.
Also known as Earth Slurry (Dijiang). Clears heat and detoxifies.
Sweet, cold. Treats diarrhea and dysentery caused by cold-heat imbalance, including red-and-white dysentery. Treats colic pain caused by heat-toxin in the abdomen. Resolves poisoning from various fish, meat, vegetables, fruits, drugs, and all kinds of fungi. ("Fungus" is pronounced like "Jun", grows on rotting wood and damp ground, also called "Xun"; fungus on maple trees causes uncontrollable laughter if eaten; taking this resolves it.) Also treats leeches entering the abdomen. (Accidentally eating horse leeches which lay eggs in the abdomen; use this to expel them.) For sudden death due to heatstroke. (Take hot soil from the roadside surrounding the navel, have someone urinate into it, still use hot soil and garlic in equal parts, pound into powder, filter dregs, and administer to revive. *Weisheng Baojian* states: Heatstroke and cholera are caused by internal injury from summer-heat and confusion of the seven emotions. When Yin Qi is quiet, the spirit is stored; when agitated, it dissipates. Only extreme Yin Qi can cure this. Kun represents Yin, Earth belongs to Yin, Soil is called quiet and compliant. Earth slurry is made in a pit in the shade of a wall, being Yin within Yin, capable of draining Yang within Yang.) Dig a pit in yellow earth, three chi deep. Pour newly drawn water in and stir until turbid. After a short while, take the clear liquid for use. (Eating yellow catfish while having taken Schizonepeta can harm the body; taking earth slurry resolves it.)
Disperses and assists Yang Qi.
Assists Yang Qi, unblocks meridians. (Wang Ying says: Hot water must be boiled vigorously (hundred boils) to be good; if only half-boiled, drinking it damages Yuan Qi and causes distension. Zong says: Hot water can unblock meridians. For those suffering from wind-cold qi bi, pour hot water over feet up to the knees, cover tightly to induce sweating throughout the body. However, there are other medicines; this merely borrows Yang Qi to move. For sudden diarrhea and dysentery in any season, with cold limbs and umbilical/abdominal coldness, sit in a deep basin of hot water, soaking up to the abdomen, doing this frequently. Among herbs that generate Yang Qi, none is faster than this. Those with deficiency-cold will tremble upon first sitting in the bath; attendants should watch constantly. Zhang Congzheng says: For initial injuries from wind-cold or dietary excess (alcohol/food), if no medicine is available, drink about one bowl of Taihe Tang, or sour pickle juice. Rub the abdomen with hands; when feeling dizzy/confused, drink again and rub until unable to hold more, induce vomiting. Sweating indicates recovery. Li Shizhen says: Zhang Zhongjing treated epigastric fullness (Pi syndrome) where palpation was soft and the pulse at Guan was floating, using Dahuang Huanglian Xiexin Tang, decocted with Mafei Tang (boiling water), to utilize its thin aroma to drain deficient heat. For years-long wind diseases, dig a pit, sit inside, undress, pour hot water for a long time, cover with a bamboo mat, sweat out to recover. This is also a method to unblock meridians. Li Shizhen often extended this idea: for cold-dampness, add Mugwort to decoct; for wind-deficiency, add Wuzhi or Wujiapi to decoct for washing, finding it faster. An says: Bathing with hot water for wind-cold common cold is also a dispersing method; thus *Neijing* mentions moxibustion with heat, bathing, and massage/bathing texts. *Beiji Fang* treats sudden severe heart/abdominal pain by soaking hands and feet in hot water, changing when cool.) Also known as Taihe Tang. Also known as Mafei Tang. (If a snake coils around and won't release, pour hot water to make it detach. For sudden death due to evil qi, fill a copper or earthenware vessel with hot water, apply through clothing to the abdomen, changing when cool.)
