Ginseng Radix (Renshen), Ophiopogonis Tuber (Maidong) 5 fen, Schisandrae Fructus (Wuweizi) 7 grains.

The Liver governs Qi mechanism, and the Heart governs Blood. Shengmai San (Pulse-Generating Powder) nourishes the Yin of the Heart and Lungs, allowing Qi and Blood to nourish the whole body; furthermore, it contains sour astringent herbs to gather scattered Qi, stop sweating, and relieve cough. It is suitable for deficient patients without external pathogenic factors during the summer months.

Talcum (Huashi) 6 liang, Licorice Root (Gancao) 1 liang.
Grind into powder, take with cold water or Decoction of Juncus Effusus (Dengxincao). When Cinnabar (Chensha) is added to this formula, it is named Yiyuan San (Benefit-One Powder); when Mint (Bohe) is added, it is named Jisu San (Chicken-Su Powder); when Indigo Naturalis (Qingdai) is added, it is named Biyu San (Jasper Powder).
Liuyi San (Six-to-One Powder) can be applied to those with robust constitutions, intense heat, and excessive internal accumulation. However, if used for those with weak constitutions and deficient Qi, the cold nature will injure Spleen Yang, and the slippery nature will injure Kidney Qi, leading to reduced appetite, fluid deficiency, and thirst. The same applies to Yiyuan San, Jisu San, and Biyu San; they should not be indiscriminately administered simply because it is summer.

Amomum Fruit (Sharen), Tsaoko Fruit (Caoguo, baked and peeled), Mume Fruit (Wumei), Roasted Licorice Root (Zhi Gancao) 4 liang, Fried and Crushed Broad Bean (Bian Dou), Kudzu Root (Gegen) 2 liang.
The pungent and drying herbs in this formula are too strong; it may be used to strengthen the Spleen and remove Dampness. However, I do not agree that it clears Summerheat, relieves irritability, or stops thirst.

Pinellia Tuber (Banxia) 1 jin (boiled dry with 5 jin of Vinegar), Poria (Fuling), Raw Licorice Root (Sheng Gancao) 0.5 jin.
Make pills using Ginger Juice (Jiangzhi), avoiding contact with raw water. Take with hot water decoction.
Xiaoshu Wan (Summerheat-Relieving Pill) does not directly treat Summerheat but treats Dampness; by removing Dampness, Summerheat also subsides, which is an excellent intention. However, it must be combined with one or two Heat-clearing and resolving herbs to be effective.

Dried Ginger (Ganjiang), Cinnamon Twig (Guizhi), Apricot Seed (Xingren, skin and tip removed), Licorice Root (Gancao) in equal proportions.
First, stir-fry Licorice Root with white sand; then add Dried Ginger and Apricot Seeds and stir-fry together. Remove the sand, mix with Cinnamon Twig, and grind into powder. Take 2 qian per dose.
This is the formula for treating Cold damage (Shanghan) during the Summerheat season. Because the condition arises from contracting Cold due to Summerheat habits, it treats only the Cold and not the Summerheat.

Polyporus (Zhuling), Poria (Fuling), Fried Atractylodes Rhizome (Chao Baizhu) 18 zhu, Alisma Rhizome (Zexie) 1 liang 6 zhu half, Cinnamon Twig (Guizhi) 5 qian.

Dampness is the Qi of the earth; its invasion of the human body is slow, its entry is deep, and its pathological manifestation cannot be resolved hastily. Sitting or lying in damp places, being soaked in sweat or rain, represents Dampness coming from outside; consuming rich and greasy foods excessively, or over-indulging in tea and alcohol, represents Dampness generated from within. To treat Dampness, one must first regulate the Spleen; only when Spleen Earth functions vigorously can it seep out Dampness—this is a fixed principle. Additionally, one must employ diuresis to separate and drain, allowing turbid Yin to exit from below—this is also a fixed principle. Wuling San (Five-Ingredient Powder with Poria), originally established by Zhang Zhongjing, was designed for cases presenting with floating pulse, difficulty in urination, slight fever, and polydipsia, involving both exterior and interior pathology. In this formula, Cinnamon Twig (Guizhi) should be used, not Cinnamon Bark (Rougui). Later practitioners extended its use to treat various Dampness conditions, abdominal fullness, fluid retention, edema, vomiting, diarrhea, Water-Cold attacking the Lung causing wheezing or cough, Summerheat with irritability and thirst, fever and headache, Bladder Heat, constipation with thirst, cholera-like vomiting and diarrhea, phlegm-fluid and Dampness syndromes, body pain, and heaviness. In summary, when treating Cold-Damp, Rougui (Cinnamon Bark) is appropriate, while Guizhi (Cinnamon Twig) is not. If severe Yin generates Yang, and accumulated Dampness transforms into Heat, Heat-clearing and draining herbs should be added, and even Guizhi should be avoided. As for the modified attached formulas, each has its specific indications and should be carefully studied.
