Jie Biao: Releasing the Exterior

Jie biao — releasing the exterior — is also called the sweat method. Pungent herbs that promote a light sweat are used while a pathogen is still in the exterior, so it is not trapped deeper in the body. It is a pattern method, not a home remedy for every fever.

1. Pungent-warm release (xin wen jie biao)

Used for wind-cold type colds: fever, headache and stiff neck, body aches, a floating tight pulse, little or no sweat. Common herbs include Ephedra (ma huang), Cinnamon twig (guizhi), Notopterygium, Saposhnikovia (fangfeng), Angelica dahurica (baizhi) and Perilla leaf. No sweat and a clearly cold exterior: ephedra is often in the formula. Heat already stirring inside: a pungent-cool pair may be added, as in Da Qing Long Tang. Sweat with aversion to wind: cinnamon twig formulas are more typical.

2. Pungent-cool release (xin liang jie biao)

Used for exterior wind-heat or dryness: fever, headache, mild chills, sweating, thirst, sore throat. Common herbs include Lonicera (jinyinhua), Forsythia (lianqiao), mulberry leaf, chrysanthemum, mint and arctium. Yin Qiao San is the representative formula.

3. Nourish yin and release the exterior (zi yin jie biao)

Used when an exterior pathogen sits on a background of yin-blood deficiency. There is not enough fluid to raise a proper sweat, so the pathogen does not leave. Yin-nourishing herbs are combined with exterior-releasing ones. Examples: Polygonatum odoratum (yuzhu), raw Rehmannia, Ophiopogon (maidong), scallion, fermented soybean, Pueraria (gegen).

4. Support yang and release the exterior (zhu yang jie biao)

When yang qi is too weak, an exterior pathogen gets in easily. Yang-boosting and exterior-releasing herbs are used together so a sweat can form. Examples: prepared aconite accessory root, ginseng, Astragalus, with fangfeng, ephedra, Asarum and Notopterygium. A representative formula is Ma Huang Xi Xin Fu Zi Tang.

5. Move qi and release the exterior (li qi jie biao)

Used when qi stagnation is part of the picture and the pathogen is sinking inward. Cyperus (xiangfu) and tangerine peel are typical companions to the exterior-releasing set.

6. Transform congested fluids and release the exterior (hua yin jie biao)

Used when an exterior pattern meets phlegm-fluids. Exterior-releasing herbs are combined with herbs that transform yin (congested fluid), such as Pinellia (banxia), dried ginger and Asarum. Xiao Qing Long Tang is the representative formula.

7. Vent rashes and release the exterior (tou zhen jie biao)

Used in the early stage of eruptive illnesses, when the problem is still on the surface and venting the rash is part of letting the pathogen out. This is a classical measles/rash method, not a treatment for polio. Herbs include Cimicifuga (shengma), Pueraria (gegen), Schizonepeta (jingjie) and arctium. A representative combination is Shengma Gegen Tang.

Choosing among these seven is a diagnostic decision. The herbal names above are the traditional tools of the method, not a shopping list.
