气味芳香，药性温和，能温中散寒并透达体表，疏散风邪、化解凝滞。发汗解表而不过于峻猛，属阳刚之性却不损伤阴液。可通鼻窍闭塞、行气机郁滞。体质虚弱之人需要发汗，但身体衰弱无法承受强力发汗药时，应当配伍人参使用。夏季感受寒凉，若用辛热药物担心违背时令（导致上火），可与藿香同用。
橘梗：能降气安胎，使胎元稳固。果实（防风子）：可消痰定喘，使喘息平息安宁。

能抵御外来风邪，所以名叫防风，是风药中的润剂。外科常用它，因为风湿交攻所致。张元素说它是“手足太阳经的本药”。王好古又说它“行足阳明、太阴二经，为肝经气分药”。又说“钱仲阳泻黄散中，倍用防风，是在土中泻木”。《日华诸家本草》说它“匀气脉”，这是经验之谈。

Pungent in flavor, warm in nature, non-toxic, enters the Lung Meridian.
Its aroma is fragrant, its nature is mild and harmonious; it warms the interior and reaches the exterior, disperses wind and resolves stagnation. It releases the exterior through sweating without being overly harsh; its yang nature does not damage yin. It unblocks nasal congestion and moves qi stagnation. For deficient individuals who need to sweat but are too weak to tolerate strong diaphoretic agents, Ginseng Radix et Rhizoma (Renshen, 人参) should be used as an adjunct. When cold-dampness is contracted during summer, if pungent-hot herbs are feared to violate the seasonal climate, they may be combined with Agastache Herba (Huoxiang, 藿香).
The stem (Jiegeng, 桔梗): can direct qi downward and calm the fetus, stabilizing the fetal foundation.
The fruit: can resolve phlegm and calm wheezing, bringing relief to panting.
This herb's warmth can disperse cold, and its fragrance can harmonize qi and blood. Like a person of great virtue, it encounters no obstacles wherever it goes. Its combination with Tangerine Peel (Chenpi, 陈皮) is particularly suitable. Huoxiang Zhengqi San (Agastache Powder for Rectifying Qi) for treating external contraction of wind-cold-dampness, and Jiming San (Crowing Rooster Powder) for treating podagra, both employ such combinations. It can also be used externally: for pregnant women with incessant vomiting, boiling the stems and leaves to inhale the steam can stop retching, direct qi downward, and restore equilibrium. It can also detoxify crab poison.
Sweet in flavor, warm in nature, non-toxic. Enters the Lung, Small Intestine, and Bladder meridians. Incompatible with Dioscorea Hypoglauca Rhizome (Bixie, 萆薢).
Hostile to Dried Ginger (Ganjiang, 干姜) and Genkwa Flower (Yuanhua, 芫花). Can neutralize Aconite Root (Fuzi, 附子) toxicity. Those that are white and moist are superior.
Disperses wind and releases the exterior, alleviates pain and treats sores. Clears the throat and teeth, treats urticaria and pruritus. Stagnant qi in the head and eyes, and retained dampness in the collaterals, can all be treated. Irritating pain in the joints, and spasmodic tightness in the four limbs, can all be relieved.
It can ward off exogenous wind, hence named Fangfeng (Windscreen). It is a moistening agent among wind-dispelling herbs. It is frequently used in dermatology because wind and dampness attack together. Zhang Yuansu stated it is "the fundamental herb for the Foot-Taiyang and Hand-Taiyang meridians." Wang Haogu further stated it "travels through the Foot-Yangming and Foot-Taiyin meridians, acting on the qi level of the Liver meridian." He also said, "In Qian Zhongyang's Xiehuang San (Drain Yellow Powder), Fangfeng is doubled in dosage to drain wood within earth." The Bencao Ri Hua Zhu Jia (Various Families of Materia Medica by Ri Hua) states it "harmonizes qi and vessels," which is based on empirical experience.
Pungent and sweet in flavor, warm in nature, non-toxic. Enters the Liver meridian. Antagonistic to donkey meat, scaleless fish, pufferfish, crab, and yellow croaker.
Disperses wind pathogens: clears the vertex. Benefits the throat, expels measles rashes. Resolves blood stasis, eliminates scrofula nodules. Manages sores and ulcers, breaks up accumulations and masses.
It excels at treating wind conditions and simultaneously addresses blood disorders. Why? Because it enters the zang-organ of wind and wood (Liver), which is the Sea of Blood, thus enabling it to treat both. It is suitable for wind pathogens located between the skin and the fascia.
