[Sappan Wood]
Taste: Sweet, salty. Nature: Neutral. Non-toxic. Born from the qi of water and earth. Descending action exceeds ascending action. It is Yin within Yang.
[Indications] Primarily breaks blood stasis. Treats postpartum abdominal distension and oppression causing extreme suffering. Boil five liang in water, take the concentrated decoction. (From *Kaibao Bencao*) Treats heart and abdominal pain caused by blood and qi disorders in women. Menstruation. (Use one Fangcunbi dose). Postpartum retained blood.
[Meridian Tropism] Enters the Liver, Spleen, and Kidney meridians. Also enters the Heart and Stomach meridians. It is a substance that releases the exterior and promotes blood circulation. (It is a medicine for the blood aspect of the Three Yin meridians.)
[Prior Discussions] Jieguo stated: Taste pungent, nature cool. Disperses wind and qi in the interior and exterior. Should be used with Fangfeng. It can also break dead blood. Shizhen stated: Use in small amounts.
[Contraindications] *Jingshu* states: If lochia has finished after childbirth and abdominal pain is due to blood deficiency, it should not be used.

Taste: Pungent. Nature: Warm. Toxic. Born during the peak of Summer Yang (the sixth Yang month). Matured in the Metal month of Autumn. Its action is descending. It is Yin. Used with Yuanhua as an assistant herb.
Incompatible with Dahuang, Huanglian, Lilu, and cold water.
[Indications] Primarily treats chills and fever from Shanghan and Wenmalaria. Breaks up masses, nodules, firm accumulations, and stubborn fluid retention or phlegm-pi. Treats massive abdominal edema. It can purge the Five Zang and Six Fu organs. Opens blockages. Treats traumatic injuries with pus and blood.
[Meridian Tropism] Enters the Stomach and Large Intestine meridians. It is a "gate-crashing" potent agent. (Also acts as a drying agent; opens orifices and unblocks stagnation.)
[Prior Discussions] Danxi stated: Chinese Croton Seed removes cold accumulation in the Stomach. Do not use if there is no cold accumulation. Haicang stated: For urgent treatment, it serves as a purgative for the pathways of food and fluids. Diarrhea. When used together with Dahuang, clearing fire becomes slower because their natures are mutually inhibitory.
[Contraindications] *Jingshu* states: Do not lightly administer in any decoction, powder, or pill form. Even in unavoidable emergency cases, it must be stir-fried until cooked, pressed to remove all oil completely. Enter...

[Meridian Tropism] Enters the Lung meridian. It is a "clearing Metal" agent. (Also acts as a drying agent; Pungency drains excess Lung pathogenic factors to stop coughing; Sweetness consolidates deficient primal Qi to tonify deficiency.)
[Prior Discussions] Luo Qianfu stated: Sangpi drains the Lung, but it drains Lung Fire pathogen, not Lung Qi. Fire and Primal Qi cannot coexist. When Fire is removed, Qi is restored... Fire enters...
[Contraindications] *Jingshu* states: If the Lung is deficient without Fire, and coughing is caused by Cold invasion, do not use Sangpi.
