[Hawthorn Fruit]
Taste: Sweet, Sour. Nature: Warm. Toxicity: Non-toxic. It is generated by inheriting the Wood Qi. Its action descends. It belongs to pure Yin.
[Indications] Mainly functions to digest food accumulation, resolve retained stagnation, move stagnant Qi, eliminate masses of accumulation, phlegm, and blood, strengthen the Spleen, open the diaphragm, and treat dysentery.

[Meridian Tropism] Enters the Spleen meridian. It is a substance that breaks Qi stagnation, eliminates accumulation, disperses blood stasis, and transforms phlegm. (Specifically removes accumulations of greasy and fishy foods, which differs from Maiya (Hordei Fructus Germinatus) which eliminates grain accumulations.)
[Preceding Discussions] Shi Ying stated: Since Zhu Danxi first documented the merits of Hawthorn Fruit, it has become an essential medicine. The seed also has efficacy, capable of resolving food and grinding away accumulation. Ning Yuan stated:
Excessive consumption causes mental restlessness and irritability with easy hunger, instead damaging the generating Qi of the Spleen and Stomach. This is because the breaking and draining action is too excessive, injuring the Middle Qi.
[Contraindications] Miao Xiyong (author of *Bencao Jing Shu*) stated: Contraindicated in cases of Spleen deficiency with poor transportation, and when there is no food accumulation in the Stomach. If Spleen and Stomach are deficient yet accompanied by accumulation, it should be administered together with tonifying medicines.
