Lily is a commonly used medicinal food that was first recorded in the Shennong Hundred Herb Classic. The ancients believed that lily moistens the lung and stops coughing, clears the heart and nourishes dryness. Lily can nourish lung yin and treat dry cough without phlegm caused by lung yin deficiency, or even dry mouth and dry heat caused by lung fire. Lotus seeds can nourish the spleen and strengthen the kidneys. For spleen and stomach deficiency, especially spleen yin deficiency, lotus seeds can have the effect of strengthening the spleen and stomach, and even have the effect of stopping diarrhea. Rock sugar itself is good for the spleen and stomach. Lotus seeds with lily can moisten the heart and lungs, clear the fire of the heart and lungs and moisten the yin of the heart and lungs, plus lotus seeds to strengthen the spleen and rock sugar to flavor it, which is very effective.
