【白芷】味辛，性温，无毒。归心经、小肠经。忌与黄芩、山茱萸同用。畏滑石。反藜芦。
治疗风寒湿邪阻滞经络引起的痹痛，头痛鼻塞。降气破痰，治疗头面部的游风（游走不定的风邪）。缓解全身关节拘挛疼痛，牙齿疼痛，流泪。
【细辛】味辛，性温，禀受升发阳气之气，作为祛风药，因其辛香能开窍，所以主治上述病症。单独服用粉末达到一钱（约3-5克），会导致人胸闷窒息，辛散药物不可多用。
细辛发表散寒，祛风止痛。温肺化除寒饮，使用得当，疗效迅速。然而其性质燥烈，凡是血虚内热，因而导致头痛咳嗽的患者，严禁使用。

淡豆豉经过蒸制和发酵，具有升散的作用，遇到葱则能发汗，遇到盐则能止吐，遇到酒则能治风，遇到薤白则能治痢。炒熟后又能止汗，也是重要的药物。
伤寒邪气直中三阴经，或传入阴经的患者，不要使用。热结胸膈导致烦闷的患者，宜用泻下法而不宜用发汗法，也忌用此药。
【浮萍】味辛，性寒，无毒。归肺经。
通达毛孔，到达肌肤，透发瘾疹（荨麻疹等皮肤疾患），瘙痒得以消除。发汗开启鬼门（汗孔），利水洁净腑（膀胱）。
浮萍轻浮，入肺经发汗，气化功能波及州都（膀胱），因而能够利水。
浮萍的发汗力量比麻黄强，利水的功效同于通草，如果不是大实大热的证候，怎么敢轻易尝试呢？
[Bai Zhi (Angelicae Dahuricae Radix)] Pungent in flavor, warm in nature, non-toxic. Enters the Heart and Small Intestine meridians. Incompatible with Huang Qin (Scutellariae Radix) and Shan Zhu Yu (Corni Fructus). Averse to Hua Shi (Talcum). Counteractive against Li Lu (Veratri Radix).
Indicated for Bi syndrome (painful obstruction) caused by wind-cold-dampness, headache, nasal congestion. Directs Qi downward, breaks up phlegm, treats wandering wind on the head and face. Relieves spasms and cramps in all joints, toothache, and tearing.
[Xi Xin (Asari Radix et Rhizoma)] Pungent in flavor, warm in nature, possessing the ascending Yang Qi, acting as a wind-dispelling agent. Its pungent aroma opens orifices, thus treating the aforementioned conditions. Taking alone as powder up to one qian (approx. 3-5g) can cause suffocation and unconsciousness; pungent dispersing herbs should not be used in large doses.
Xi Xin releases the exterior and dispels cold, expels wind and alleviates pain. Warms the Lung and transforms fluid retention; when used appropriately, it yields rapid results. However, its nature is dry and fierce. It is strictly contraindicated for those with blood deficiency and internal heat leading to headache and cough.
[Bo He (Menthae Haplocalycis Herba)] Pungent in flavor, warm in nature, non-toxic. Enters the Lung meridian. Those produced in Suzhou are of superior quality.
Disperses wind-heat, clears the head and eyes. Benefits the throat, cleanses gums and tongue. Dispels bad breath, unblocks nasal congestion. Expels sha-rash (scarlatiniform rash), unblocks joints. Directs stagnant Qi downward, removes foulness.
Because it induces sweating to release the exterior, it dispels wind and clears heat, benefiting the head and face. Because its pungent aroma moves Qi, it also treats distension and food stagnation.
Bo He's pungent aroma depletes Qi; excessive consumption damages the Lung and Heart Qi.
[Dou Chi (Sojae Semen Praeparatum)] Sweet and bitter in flavor, cold in nature, non-toxic. Enters the Lung and Spleen meridians.
Releases the muscle layer and induces sweating, eliminating headache along with chills and fever. Directs Qi downward and clears irritability; effective for chest and epigastric fullness and heat disorders. Applicable for epidemic qi and miasma. Suitable for dysentery and malaria. Externally applied to treat sores in the mouth and tongue; decoction saved for laryngeal bi (obstruction) with aphonia.
Dou Chi, after steaming and fermenting, has ascending and dispersing properties. Combined with Cong Bai (Allii Macrostemonis Bulbus), it induces sweating; combined with Yan (Sal), it stops vomiting; combined with Jiu (Alcohol), it treats wind; combined with Xie Bai (Allii Macrostematis Bulbus), it treats dysentery. When stir-fried, it can stop sweating. It is an important herb.
Contraindicated in Shang Han (Cold Damage) where pathogens directly invade the Three Yin meridians, or have transmitted into the Yin meridians. Contraindicated in heat accumulation in the chest causing irritability, where purgation is indicated rather than diaphoresis.
[Fu Ping (Spirodelae Herba)] Pungent in flavor, cold in nature, non-toxic. Enters the Lung meridian.
Opens hair follicles, reaches the skin, expels urticaria, relieves itching. Induces sweating by opening the "Ghost Gate" (sweat pores), promotes urination to cleanse the Fu organs (Bladder).
Fu Ping is light and floating; entering the Lung meridian to induce sweating, its Qi transformation affects the Zhou Du (Bladder), thereby promoting urination.
The sweating power of Fu Ping is stronger than Ma Huang (Ephedrae Herba); its water-draining efficacy is similar to Tong Cao (Tetrapanacis Medulla). If not a case of excess and extreme heat, how dare one lightly try it?
