按∶白芷味辛，为肺所喜，而温燥为脾胃所喜，宜其入矣。然香燥而发散，主治虽多，

紫苏：味甘、辛，性温，无毒，归肺经和脾经。其叶能发汗解表，温暖胃气并调和脾胃，消除头痛及肢体关节疼痛，以叶片双面呈紫色的为佳。不敢使用麻黄的患者，可用紫苏叶代替。紫苏梗能顺理气机并安胎。紫苏子能开郁结、降逆气，平定喘息并消除痰饮。
按语：辛味入肺，甘味入脾。辛散的药物中，降气作用最为迅速，体虚者应少量使用。
白芷：味辛，性温，无毒，归肺、脾、胃三经。能祛除头面皮肤的风邪，消除肌肉干燥瘙痒的痹证，止住阳明经头痛的病邪，是肺经的引经药。主治排脓、托毒生疮、生肌长肉、通经络利孔窍、止漏下除崩漏、明目散风、驱寒燥湿。若与当归配伍则作为使药，忌与旋复花同用。
按语：白芷味辛，为肺脏所喜，其温燥之性为脾胃所喜，故适宜入此三经。然而其气味香燥且具发散之力，虽主治病症众多，但易损伤气血，不宜多用。
雷公云：凡是采得后，有四种情况不可使用：生长在低洼处的，名为张公藤，兼也不可使用马蔺，这些都不入药。采得后需刮削去皮，细切，取黄精也细切，用竹刀将这两味药等分，一同蒸一个时辰（约两小时），取出后在日晒下晒干，去掉黄精后使用。
防风：味辛、甘，性温，无毒，归肺经。能泻肺金之气，治疗各种风邪，开通郁结之气，调理目痛。忌与干姜、藜芦、白蔹、芫花同用，能解附子之毒。
按语：防风辛味入肺，属于升阳的药物，因此能通治各种风邪。气机郁结是肺的疾患，目痛是风邪的祸患，所以防风适宜同时主治这些病症。李东垣说：防风如同卑贱的士兵，听令而行，随所引导而至，是风药中的润剂，能泻上焦邪气，元气虚者不普遍使用，如今人们常犯此弊病。
独活：味苦、甘、辛，性微温，无毒，归肺经和肾经。主治新旧各种风湿痹证，颈项僵硬难以伸展，腰背酸痛，四肢挛缩痿软，身体发黄且出现块状物的是独活。
按语：独活气浊属阴，善于行血分，收敛而能舒展，沉降而能上升，缓慢而善于搜剔伏邪，可辅助表虚，因此入太阴肺经和少阴肾经，以治理潜伏的风邪。
Perilla Fructus (Zi Su Zi): Sweet and acrid, warm, non-toxic. Enters the Lung and Spleen meridians. The leaves can induce sweating to release the exterior, warm the stomach and harmonize the middle jiao, relieve headache and pain in the limbs and joints. Those with purple on both sides of the leaf are superior. For those who dare not use Ephedrae Herba (Mahuang), this serves as a substitute. The stem can regulate qi and calm the fetus. The fruit can resolve stagnation, direct rebellious qi downward, stabilize asthma, and eliminate phlegm.
Commentary: Acrid flavors enter the Lung, sweet flavors enter the Spleen. Among acrid dispersing agents, directing qi downward is most rapid; those with deficiency should use it sparingly.
Angelica Dahurica (Bai Zhi): Acrid, warm, non-toxic. Enters the Lung, Spleen, and Stomach meridians. It expels wind from the head, face, and skin, removes bi-syndrome characterized by dryness and itching of the muscles, stops pathogenic factors causing Yangming headache, and acts as a guiding herb for the Lung meridian. It mainly promotes pus discharge, supports ulcer healing, generates flesh, unblocks collaterals and benefits orifices, stops leakage and metrorrhagia, brightens the eyes, dispels wind, drives out cold, and dries dampness. When used with Angelica Sinensis (Danggui), it acts as an envoy herb. It is incompatible with Inulae Flos (Xuan Fu Hua).
Commentary: Bai Zhi is acrid, which is favored by the Lung, and its warm-drying nature is favored by the Spleen and Stomach, hence its suitability for entering these meridians. However, being aromatic, drying, and dispersing, although it treats many conditions, it can damage qi and blood, so it should not be used excessively.
Lei Gong stated: After harvesting, do not use four types: those growing in low places, known as Zhanggong Teng, nor use Iris lactea (Malin); these are not used in medicine. After harvesting, scrape off the skin, cut finely. Take Polygonatum Rhizoma (Huangjing), also cut finely. Using a bamboo knife, slice equal parts of both, steam together for one shichen (approx. 2 hours), then sun-dry. Remove Huangjing before use.
Saposhnikovia Root (Fang Feng): Acrid and sweet, warm, non-toxic. Enters the Lung meridian. It drains Lung metal, treats various winds, opens stagnant qi, and regulates eye pain. Incompatible with Dried Ginger (Ganjiang), Veratrum Rhizome (Lilu), Ampelopsis Radix (Bailian), and Genkwa Flos (Yuanhua). It resolves Aconiti Lateralis Radix Preparata (Fuzi) toxicity.
Commentary: Fang Feng is acrid and enters the Lung; it is an agent that raises yang, thus effectively treating various winds. Qi stagnation is a disease of the Lung; eye pain is a affliction of wind, so it appropriately treats both. Li Dongyuan said: Fang Feng is like a humble soldier, obeying orders and going wherever guided; it is a moistening agent among wind-dispelling herbs, capable of draining the upper jiao. It is not generally used for those with deficient yuan qi, yet modern people often commit this error.
Angelica Pubescens (Du Huo): Bitter, sweet, and acrid, slightly warm, non-toxic. Enters the Lung and Kidney meridians. It mainly treats old and new wind-damp bi-syndromes, stiffness and difficulty extending the neck, soreness and pain in the waist and back, spasms and flaccidity of the four limbs. Those presenting with yellowish complexion and nodular masses are Du Huo.
Commentary: Du Huo has turbid qi and belongs to yin. It excels at moving blood, is astringent yet soothing, sinking yet ascending, slow yet good at searching out pathogens. It can assist with exterior deficiency, thus entering the Taiyin Lung and Shaoyin Kidney meridians to treat latent wind.
