At the vernal equinox, the liver qi is strong, which affects the spleen and stomach, because the liver belongs to wood, the stomach belongs to soil, and the wood belongs to soil. So the spleen and stomach are weak in spring. Chinese medicine believes that the general principle of nourishing the stomach in spring is "reducing acidity and increasing sweetness, and drinking more porridge".

Hypoacidity is because "acid produces liver". In spring, the liver qi is strong, and eating more acid will "burn oil". More because of the sweet "sweet chest addiction". The spleen never leaves the stomach, and the stomach never leaves the spleen. When the spleen is well, the stomach is naturally well. And porridge is the most nourishing food.
