It is used for Yin deficiency in the lung and stomach, dry and hot cough, dry throat and mouth, and internal heat with polydipsia. The suitable extensive management of Polygonatum odoratum is of great significance for enriching the resources of ornamental plants in adverse conditions and building ecological and energy-saving gardens. Its flowers, fruits and leaves all have high ornamental value and it is an excellent ground cover plant.

1. Efficacy and Function
1. Nourishing yin and moistening dryness
Yuzhu is sweet and moist, slightly cold in nature, and good at nourishing the yin of the lungs and stomach. It can alleviate problems caused by yin deficiency, such as dry throat and mouth, dry skin, and constipation. It is especially suitable for conditioning during the dry autumn season or in the later stages of heat diseases.
2. Promote saliva production and quench thirst
It can promote saliva secretion, improve appetite loss caused by insufficient stomach yin, red tongue with scanty tongue coating, and thirst symptoms associated with diseases such as diabetes.
3. Moistening the lungs and relieving cough
It has a soothing effect on dry coughs due to lung dryness, with little or no phlegm. It is often used in combination with ingredients such as sand ginseng and ophiopogon japonicus for conditions like chronic bronchitis and pulmonary tuberculosis, which are characterized by lung yin deficiency.
4. Enhance immunity
Modern research indicates that Polygonatum odoratum polysaccharides possess antioxidant and immune-regulating properties, and can assist in improving physical weakness or post-illness fatigue.
