口，是全身的要冲门户，是气血营养出入的重要通道，如果调节稍有失调，疾病必然产生。所以热证则口苦，寒证则口咸，宿食停滞则口酸，烦躁不安则口涩，虚证则口淡，黄疸病则口甘。五味入口，贮藏于胃和脾，运化其精华，将津液分布到五脏，若脏气偏盛，口味必然相应地出现偏向，或者因为劳倦郁结而口臭，气机凝滞而生疮，不可失去睡眠，一旦失睡，病情会更加加重。

Qianghuo (Radix Notopterygii) [3 liang], Fuling (Poria), Yiyiren (Semen Coicis) [each 1 liang].
Grind the above into powder. Take 2 qian per dose, decoct with one large cup of water until reduced to 70%, add one spoonful of Danzhuli (Bamboo Sap), decoct again, and take.
Treats deficiency of Qi in the Spleen and Lung, excessive worry and overthinking, leading to exhaustion of Ying and Wei (Nutritive and Defensive Qi), resulting in cracked and tight lips; or sores at the corners of the mouth, withered and haggard complexion; seminal emission in men, and blood deficiency in women. This formula treats all these conditions.

The mouth is the main gate of the body and the crucial pathway for the entry and exit of Ying and Wei nourishment. If its regulation is slightly impaired, disease will inevitably arise. Thus, heat causes bitterness, cold causes saltiness, retained food causes sourness, irritability causes astringency, deficiency causes blandness, and jaundice causes sweetness. The five flavors enter the mouth, are stored in the Stomach and Spleen, their essence is transported, and fluids are distributed to the Zang organs. If the Qi of an organ is excessive, the taste will correspondingly be biased. Alternatively, labor and stagnation may cause bad breath, and stagnation may cause sores. Sleep must not be lost; loss of sleep will exacerbate the condition.
