What is Mulberry Leaf?

Mulberry Leaf (sang ye, 桑叶) refers to the dried leaves of the Mulberry tree, which is found throughout China and cultivated across many parts of the world. In China, every part of the Mulberry plant has its unique and diverse therapeutic uses. The berries are bottled as a beverage to enhance immunity and promote good health. The bark is honey-fried to enhance its functions in stopping coughing and wheezing. The leaves are also used as an external wash for eye problems.

Mulberry Leaf is green and spade-shaped, and it is the only food that silkworms feed on. Mulberry Leaf is harvested in Autumn or after the First Frost before being dried for usage in herbal remedies.

In Traditional Chinese Medicine (TCM), Mulberry Leaf falls under the category of ‘Cool/Acrid herbs that release the Exterior’. Such herbs release the Exterior by treating the early stages of diseases that affect the upper respiratory tract, the eyes, the ears, the nose, the throat or the skin.

Cold in nature, Mulberry Leaf helps people who have too much Heat in their body, such as those experiencing Yang Excess or Yin Deficiency, to restore a healthy yin-yang balance. Bitter and sweet, the herb also cleanses the body by clearing Heat, drying Dampness and promoting elimination via urination or bowel movements. Mulberry Leaf can also slow down acute reactions, detoxify the body and has a tonic effect on the body by replenishing qi and blood. In particular, Mulberry Leaf targets the Liver and the Lungs.

Mulberry Leaf can disperse Exterior pathogens and clear heat to address Warm diseases. For example, it can relieve fever, itching throat, cough, sore throat and the common cold.
