味苦辛，性寒无毒，入肝经。主瘰 瘿瘤，湿脾脚肿，肝虚目痛，冷泪羞明，散血破症，

【夏枯草】
味苦、辛，性寒，无毒，归入肝经。主治瘰疬（颈部淋巴结结核）、瘿瘤（甲状腺肿大），脾湿导致的脚部肿胀，肝虚引起的目痛，冷泪迎风羞明，散血破瘀，生肌解毒。以土瓜为引药。
按语：夏枯草在三月四月开花，此时正值厥阴风木主令之时，它是肝经药物的特征非常明显。朱丹溪说：夏至时就枯萎的原因，是因为它禀受纯阳之气，得到阴气就会枯萎。
【藿香】
味甘、辛，性微温，无毒，归入肺、脾、胃三经。开通胃口，增进饮食，止住霍乱，消除呕吐逆气。
按语：藿香辛温，入肺经以调畅气机；甘温，入脾胃以调和其中。治疗节度适宜，中焦脾胃功能正常，则脏腑安宁，疾病从何而来？
【荆芥】
味苦、辛，性微温，无毒，归入肺、肝二经。主治气结瘀血，饮酒损伤及食积停滞，能发汗，祛除皮毛诸风，凉血热，治疗痛痒各类疮疡，其治疗产后眩晕效果如神，陈久的药材疗效更好。
按语：荆芥行血疗风，因此进入太阴、厥阴经，是理所当然的。现在的人只要遇到风证，就随意使用荆芥和防风，这是流传下来的“流气散”习惯罢了，不知道风邪在皮里膜外者，由荆芥主治，不像防风那样深入骨肉。有汗者不宜使用。
【香薷】
味辛，性微温，无毒，归入肺、胃二经。主治降气，消除烦热，定止霍乱，停止呕吐，治疗腹痛，消散水肿，调理中焦温暖胃腑，最能解暑气。
按语：香薷性温，它除热解暑的功效为何如此显著！不知道在炎热酷暑之时，脏腑内部潜伏着阴寒，胸腹有凝结之患，而皮肤多有蒸腾发热之气，得到香薷的辛味来发散它，温性来解除它，那么伤暑的病症，从此就远离了。热服会导致腹泻，久服会耗损人的真气。江西产硬梗石缝中生长的品质较好，土香薷苗软，只能解暑，其他方面无效。
[Xiakucao (Prunellae Spica)]
Taste: Bitter, Acrid. Nature: Cold. Toxicity: Non-toxic. Meridian Tropism: Liver Meridian. Indications: Mainly treats scrofula (lump in the neck), goiter (thyroid swelling), edema of the feet due to Spleen dampness, eye pain due to Liver deficiency, cold tearing with photophobia, disperses blood and breaks stasis, generates flesh and resolves toxicity. Guided by Digerae Fructus (Tugua).
Commentary: Xiakucao blooms in the third and fourth lunar months, a time when the Jueyin Wind-Wood phase is dominant; thus, its nature as a herb for the Liver Meridian is evident. Zhu Danxi stated: The reason it withers at the Summer Solstice is that it possesses pure Yang Qi, and withering occurs upon receiving Yin Qi.
[Huoxiang (Agastaches Herba)]
Taste: Sweet, Acrid. Nature: Slightly Warm. Toxicity: Non-toxic. Meridian Tropism: Lung, Spleen, and Stomach Meridians. Indications: Opens the appetite, promotes food intake, stops cholera-like symptoms (acute gastroenteritis), eliminates vomiting and regurgitation.
Commentary: Huoxiang is acrid and warm, entering the Lung Meridian to regulate Qi; sweet and warm, entering the Spleen and Stomach to harmonize the Middle Jiao. When treatment is appropriate and the Middle Jiao functions correctly, the Zang-Fu organs are pacified, and how could disease arise?
[Jingjie (Schizonepetae Herba)]
Taste: Bitter, Acrid. Nature: Slightly Warm. Toxicity: Non-toxic. Meridian Tropism: Lung and Liver Meridians. Indications: Mainly treats Qi stagnation and blood stasis, alcohol injury and food retention, induces sweating, expels wind from the skin and hair, cools blood heat, treats various sores with pain and itching, and is miraculous in treating postpartum dizziness. Aged herbs are superior.
Commentary: Jingjie moves blood and treats wind, so its entry into the Taiyin and Jueyin meridians is fitting. Nowadays, people indiscriminately use Jingjie and Fangfeng whenever wind syndromes occur, following the tradition of "Qi-Flowing Powders." They do not realize that Jingjie treats wind located between the skin and fascia, unlike Fangfeng which penetrates deep into bones and muscles. It should not be used in patients with spontaneous sweating.
[Xiangru (Moslae Herba)]
Taste: Acrid. Nature: Slightly Warm. Toxicity: Non-toxic. Meridian Tropism: Lung and Stomach Meridians. Indications: Mainly directs Qi downward, eliminates vexation and heat, stabilizes cholera-like symptoms, stops vomiting, treats abdominal pain, dissipates edema, regulates the Middle Jiao and warms the Stomach, and is most effective in resolving summerheat.
Commentary: Xiangru is warm in nature; why is its efficacy in clearing heat and resolving summerheat so prominent? One must understand that during intense heat and summer heat, Yin cold lurks within the Zang-Fu organs, causing condensation in the chest and abdomen, while the skin has steaming hot Qi. The acridity of Xiangru disperses this, and its warmth resolves it, thereby keeping summerheat injury at bay. Taken hot, it may cause diarrhea; taken long-term, it depletes true Qi. Those grown in stone crevices in Jiangxi with hard stems are of good quality. Tu Xiangru has soft shoots and can only resolve summerheat, being ineffective for other purposes.
