Wenli San (Clam Shell Powder)
Wenli [Lithotrix Aragonitica] (five liang)
Take the above single herb, pound it into a powder. Mix one fangcun bi (a measure of volume roughly equivalent to a square inch scoop) with five he (a unit of liquid volume) of boiling water and take orally.

Jiegeng [Platycodonis Radix] (three fen) Beimu [Fritillariae Bulbus] (three fen) Badou [Crotonis Fructus] (one fen, peeled, boiled, and ground into a paste-like consistency)
Take the first two herbs, grind them into fine powder. Add the Badou and pound again in a mortar. Take orally mixed with rice water. Strong individuals take half a fangcun bi; weak individuals reduce the dosage. If the pathology is located above the diaphragm, vomiting will inevitably occur after administration. If the pathology is located below the diaphragm, diarrhea will inevitably occur. If there is no diarrhea after administration, drink one cup of hot porridge to promote bowel movement. If diarrhea persists excessively, drink one cup of cold porridge to stop it. If body heat and cutaneous miliary eruptions persist without relief, and the patient desires to cover themselves with clothing, washing the body with cold water will only prevent the heat from dissipating. If sweating should occur but does not, restlessness will arise. If sweating has occurred but abdominal pain follows, use Shaoyao [Paeoniae Radix Alba] three liang, following the aforementioned method. (Abdominal pain after sweating indicates blood depletion leading to dryness of the Liver Wood; Shaoyao clears wind-heat, soothes the Liver Wood, and moistens blood dryness.)

Wind-cold external contraction may present with heat in the Upper Jiao, heat in the Lower Jiao, heat in the Qi level, or heat in the Blood level. Heat in the Upper Jiao and Qi level can be cleared by Baihu Tang (White Tiger Decoction). Heat in the Upper Jiao and Blood level can be purged downward by Chengqi Tang (Descending Qi Decoction). Bladder heat accumulation, located in the Blood level of the Lower Jiao, requires adding blood-breaking herbs to Chengqi Tang. Thus, formulas such as Taohe Chengqi Tang (Peach Kernel Descending Qi Decoction) and Didang Wan/Pills (Definitely Severe Pills) were established. In diseases of Shanghan (Cold Damage), the pathology lies in the Wei Qi (Defensive Qi) and Ying Qi (Nutritive Qi). Qi stagnation generates cold sensations; in Zhongfeng (Wind Stroke), the pathology lies in the Ying Blood. Blood stagnation generates heat. Heat accumulation in the Blood level characterizes a Zhongfeng syndrome, not a Shanghan syndrome. However, in individuals with abundant Yang energy who contract Shanghan and exhibit this pattern, Didang Wan (Pills) are used instead of Didang Tang (Decoction) because the lower heat is less severe than that caused by Zhongfeng.

In Taiyang disease (Taiyang Syndrome) that fails to resolve, heat accumulates in the Bladder. The patient exhibits a manic-like state (ru kuang). If stasis blood discharges spontaneously, the condition resolves. If the exterior syndrome remains unresolved, attack is contraindicated; one must first resolve the exterior. Once the exterior is resolved, if only urgency and binding sensation in the lower abdomen remain, attack is permissible. Taohe Chengqi Tang (Peach Kernel Descending Qi Decoction) is indicated.
In Taiyang disease, if the exterior syndrome is unresolved, internal steaming of meridian heat accumulates in the Bladder. The Bladder is the Fu organ of the Taiyang channel and belongs to the Water Fu organs. If the Bladder harbors pre-existing damp-heat, and due to exterior constraint, interior Fu heat erupts, the exterior heat penetrates deeply along the meridian and accumulates. Heat accumulation causes the manic-like state because Bladder heat accumulation necessarily affects the Blood Chamber. Blood is governed by the Heart; the fetal Emperor Fire nurtures the Yang Spirit. Blood heat disturbs the Heart Spirit, resulting in mania. If stasis blood discharges spontaneously, heat is expelled with the blood, and the condition heals without treatment. If it does not discharge, purgation is appropriate. If exterior symptoms are unresolved, attack is contraindicated; attacking prematurely risks the collapse of exterior Yang into the interior. One must first resolve the exterior symptoms. Once exterior symptoms are eliminated and only lower abdominal urgency and binding remain, attack is permissible. Taohe Chengqi Tang (Peach Kernel Descending Qi Decoction) is indicated. In this formula, Guizhi [Cinnamomi Ramulus] and Taoren [Persicae Semen] unblock meridians and break stasis; Dahuang [Rhei Radix et Rhizoma] and Mangxiao [Natrii Sulfas] purge stasis and drain damp-heat; Gancao [Glycyrrhizae Radix] protects the Middle Qi.
