予制此药普送，只前七味，服者多效。或问∶药极轻微，而取效甚广，何也？予曰∶药
不贵险峻，惟期中病而已，此方系予苦心揣摩而得也。盖肺体属金，畏火者也，过热则咳；
金性刚燥恶冷者也，过寒亦咳。且肺为娇脏，攻击之剂既不任受，而外主皮毛，最易受邪，
不行表散则邪气留连而不解。经曰∶微寒微咳。寒之感也，若小寇然，启门逐之即去矣。医
者不审，妄用清凉酸涩之剂，未免闭门留寇，寇欲出而无门，必至穿逾而走，则咳而见红。
肺有二窍，一在鼻，一在喉。鼻窍贵开而不闭，喉窍宜闭而不开。今鼻窍不通，则喉窍将启
能无虑乎？本方温润和平，不寒不热，既无攻击过当之虞，大有启门驱贼之势。是以客邪
易散，肺气安宁。宜其投之有效欤？附论于此，以谘明哲。

Treats various types of cough.
Jiegeng (Stellariae Radix, stir-fried), Jingjie (Schizonepetae Herba), Ziwan (Asteris Radix, steamed), Bubai (Stemonae Rhizoma, steamed), Baiqian (Cynanchi Stauntonii Rhizoma et Radix, steamed, each 2 jin), Gancao (Glycyrrhizae Radix et Rhizoma, stir-fried, 12 liang), Chenpi (Citri Reticulatae Pericarpium, washed to remove the white pith, 1 jin).
Grind all ingredients into a fine powder. Take 3 qian per dose, mixed with boiling water. Administer after meals and before bedtime. If it is an initial contraction of wind-cold, mix with ginger decoction.
I prepared this medicine for general distribution, using only the aforementioned seven herbs, and most users found it effective. Someone asked: "The medicinal properties are extremely mild, yet the efficacy is very broad. Why?" I replied: "Medicines are not valued for being drastic or hazardous, but for hitting the target of the disease accurately. This formula was obtained through my painstaking deliberation." The lung's constitution belongs to Metal, which fears Fire; excessive heat causes coughing. The nature of Metal is rigid and dry, abhorring Cold; excessive cold also causes coughing. Moreover, the Lung is a delicate organ that cannot tolerate harsh attacking agents. Externally, it governs the skin and hair, making it most susceptible to pathogenic factors. If exterior-releasing and dispersing methods are not employed, the pathogen will linger unresolved. The Classics state: "Slight cold leads to slight cough." This is the manifestation of Cold invasion, resembling a small thief; opening the door to drive it away removes it. Physicians who fail to examine carefully may recklessly use cooling or astringent agents, inevitably resulting in "locking the door and keeping the thief inside." The pathogen, wanting to exit but having no way out, must penetrate and scatter, leading to coughing with blood. The Lung has two orifices: one in the nose and one in the throat. The nasal orifice should be open and not closed, while the laryngeal orifice should be closed and not open. Now, if the nasal orifice is blocked, the laryngeal orifice will be forced open; can one remain unconcerned? This formula is warm and moistening, peaceful, neither cold nor hot. It avoids the risk of excessive attacking action and possesses the momentum of opening the door to drive out the thief. Therefore, the exogenous pathogen is easily dispersed, and Lung Qi becomes tranquil. This is likely why it is effective when administered. I attach this discussion to consult the wise.
To stop cough and relieve asthma.
Renshen (Panacis Ginseng Radix, 5 fen), Hutaorou (Juglandis Semen, 3 qian, ground with skin), Shengjiang (Zingiberis Rhizoma Recens, 3 slices).
