又名假苏。
药性轻扬，善于宣散，能发表祛风，调理血液。
味道辛苦而性温，气味芳香而具有发散作用。入肝经气分，兼行血分。其性质升浮，能够发汗（另有说法称：可止冷汗、虚汗），疏散风湿，清利头目，通畅咽喉。治疗伤寒引起的头痛，中风导致的口噤不开，身体僵硬项背强直，口眼歪斜，眼中出现黑花视物模糊。
其气温和而发散，能帮助脾胃消化食物（因香气入脾），通利血脉。治疗吐血、衄血、肠风下血，妇女崩漏及血痢，产后血晕（产后失血过多，腹部空虚，则内生风邪。因此常有崩漏眩晕的隐患，并非等待外风侵袭所致。荆芥最能消散血中的风邪，华佗愈风散，用荆芥三钱，微焙后研为末，用豆淋酒调服，或用童便服用，各家医书都说效果显著），瘰疬疮肿。清热散瘀，破结解毒（郁结散开、热邪清除，则血液清凉而毒邪解除，是治疗风病、血病、疮疡的圣药）。荆芥功效本在于治风，又兼治血的原因，是因为它进入属风木的肝脏，也就是藏血的地方。李士材说：风邪在皮里膜外，荆芥主治，不像防风那样能深入骨肉。
连穗一起使用（因为穗位于顶端，所以善于升发），治疗血证时炒黑使用（凡是用于血的药物如山栀、干姜、地榆、棕榈、五灵脂等，都应该炒黑，因为黑色胜过红色）。与鱼蟹、河豚、驴肉相克（不宜同食）。
连穗使用。
药性微寒，性质升浮。形状像心（实际上是因为莲房有瓣状结构），苦味入心，所以入手少阴心经、厥阴心包经（心、心包）的气分以泻火，兼除手、足少阳经（三焦、胆）、手阳明大肠经气分的湿热。消散各经的血凝、气聚（营气壅遏，卫气郁滞，遂成疮肿），利水通经，杀虫止痛，消肿排脓（都是结者散之的原则。凡肿胀且疼痛的是实邪，肿胀而不痛的是虚邪，肿胀且发红的是结热，肿胀而不红的是留气停痰），是十二经疮疡的圣药（《内经》说：各种疮疡痛痒都归属于心火）。
Also known as Jiasu (Fake Perilla).
Light in nature, diffusing and dispersing; releases the exterior, dispels wind, regulates blood.
Pungent and bitter in taste, warm in property, aromatic and dispersing. Enters the Qi level of the Liver Meridian, and also acts on the Blood level. Its nature is ascending and floating, capable of inducing sweating (another view states it can stop cold sweat and deficiency sweating), disperses wind-dampness, clears the head and eyes, benefits the throat. Treats headache caused by Shanghan (Cold Damage), lockjaw due to stroke, stiffness of the body and neck, facial paralysis (deviation of mouth and eye), and visual disturbances such as seeing black spots.
Its warmth and dispersing nature aids the Spleen in digestion (aroma enters the Spleen), unblocks and promotes the flow of blood vessels. Treats hematemesis (vomiting blood), epistaxis (nosebleed), intestinal wind bleeding, uterine bleeding (metrorrhagia) and bloody dysentery, postpartum blood syncope (after excessive blood loss during childbirth, emptiness in the abdomen generates internal wind. Thus, there is often a risk of metrorrhagia and syncope without waiting for external wind invasion. Jingjie is best at dispersing wind within the blood; Hua Tuo's Yufeng San uses 3 qian of Jingjie, lightly roasted and powdered, taken with Doulin wine or child's urine; various texts claim it is very effective), scrofula, and sores/swellings. Clears heat, dissipates stasis, breaks up accumulations, and resolves toxicity (when accumulation disperses and heat clears, blood cools and toxin resolves; it is the supreme herb for wind diseases, blood diseases, and sores). The reason Jingjie's function treats wind but also blood is that it enters the Liver, the organ of Wind-Wood, which is also the repository of blood. Li Shicai said: When wind is in the subcutaneous tissue and fascia, Jingjie is the primary treatment, unlike Fangfeng which can penetrate into bones and muscles.
Use with the spike (since the spike is at the apex, it excels in ascending and diffusing); for treating blood disorders, use charred (for all herbs used for blood like Zhizi, Ganjiang, Diyü, Zonglü, Wulingzhi, etc., they should be charred because black overcomes red). Incompatible with fish, crab, pufferfish, and donkey meat.
Use with the spike.
Slightly cold in property, ascending and floating. Shape resembles the heart (actually due to the lobed structure of the lotus pod). Bitter taste enters the Heart, thus entering the Qi level of the Hand-Shaoyin (Heart) and Jueyin (Pericardium) meridians to drain fire, and also clears damp-heat from the Qi level of the Hand-Yangming (Large Intestine) and Foot-Shaoyang (Sanjiao/Gallbladder) meridians. Dissipates blood stasis and Qi stagnation in various meridians (when Ying Qi is obstructed and Wei Qi is stagnant, sores and swellings form), promotes urination, unblocks menstruation, kills parasites, relieves pain, reduces swelling, and discharges pus (all follow the principle of dispersing accumulations. Swelling with pain indicates excess pathogen; swelling without pain indicates deficiency pathogen; swelling with redness indicates constrained heat; swelling without redness indicates retained Qi and stagnant phlegm). It is the supreme herb for sores and ulcers in the twelve meridians (The Classic states: All sores and itching belong to Heart Fire).
