[Preface] The six qi (pathogenic factors) invading the human body: deep invasion is termed "Zhong" (Stroke/Severe Attack), moderate invasion is termed "Shang" (Injury), and light invasion is termed "Ganmao" (Common Cold); this is the view of people in modern times, whereas ancient enlightened physicians did not distinguish these categories. I, Wu Kun, born in this era, follow the views of contemporary people; therefore, I examine formulas from five directions to treat Ganmao.
Zisuye (Perilla Leaf), Xiangfu (Cyperi Rhizoma, processed with vinegar, 2 liang each), Chenpi (Citri Reticulatae Pericarpium, white part removed, 1 liang), Gancao (Licorice Root, half liang).
For Ganmao caused by wind pathogen in all four seasons, presenting with headache and fever, this formula is indicated.
The wind qi in the south is gentle; when injured by wind-cold, it is commonly called Ganmao. "Ganmao" refers to the condition where the pathogen is superficial on the skin and muscles. The *Neijing* states: In low-lying areas, spring qi often persists; thus, in the southeastern low-lying regions, cases of wind pathogen infection are numerous. This causes headache and fever without evident Six Channels (Taiyang, Yangming, Shaoyang, Taiyin, Shaoyin, Jueyin) syndromes because the pathogen enters through the nose and resides in the upper jiao, not affecting the Six Channels, hence manifesting only as headache and fever. In this formula, Zisu, Xiangfu, Chenpi...
Chuanxiong (Ligusticum Rhizome, 7 he), Banxia (Pinelliae Tuber, 6 qian, processed), Chaihu (Bupleuri Radix, radix tip removed), Fuling (Poria, 5 qian each), Zisuye (Perilla Leaf), Gange (Puerariae Radix, 3 qian 5 fen each), Chenpi (Citri Reticulatae Pericarpium, white part removed), Zhike (Aurantii Fructus Immaturus, pulp removed), Jiegeng (Platycodonis Radix), Gancao (Licorice Root, 3 qian each).
For external symptoms of headache, fever, and aversion to cold, combined with internal symptoms of cough, expectoration, and qi rebellion (asthma/wheezing), this formula is indicated.
Chuanxiong, Zisuye, Gange, and Chaihu are exterior-resolving herbs; once the exterior is resolved, headache, fever, and aversion to cold will heal spontaneously; Jiegeng, Banxia, Chenpi, Zhike, Fuling, and Gancao are interior-harmonizing herbs; once the interior is harmonized, cough, expectoration, and qi rebellion will be eliminated.
Chuanxiong, Gancao, Mahuang (Ephedrae Herba), Gange, ChiShaoyao (Paeoniae Radix Rubra), Shengma (Cimicifugae Rhizoma), Baizhi (Angelicae Dahuricae Radix), Chenpi, Xiangfu, Zisu (equal parts).
This is a general formula for treating external contraction of wind-cold.
Ancient physicians treated wind-cold by differentiating according to the Six Channels before prescribing medication. However, there are cases presenting merely with fever, headache, aversion to cold, and nasal congestion, where Six Channels syndromes are not prominent; thus, herbs that release the exterior and promote qi circulation are generally used. In this formula, Chuanxiong, Mahuang, Gange, Shengma, Baizhi, Zisu, Xiangfu... and Gancao serve to harmonize yang qi within the group of dispersing and regulating herbs.
