Mulberry Leaf (Sang Ye): A Cooling Herb for Lungs, Eyes, and Heat Relief

Introduction

Mulberry leaf, known as Sang Ye (桑叶) in Traditional Chinese Medicine (TCM), is a cooling and light herb traditionally used to disperse wind-heat, moisten dryness, and clear Lung heat. With its sweet, slightly bitter, and cold nature, Sang Ye is commonly used for dry coughs, sore throats, red eyes, and early-stage colds. It is a gentle yet powerful remedy for calming internal heat while supporting respiratory and eye health.

What Is Mulberry Leaf?

Sang Ye refers to the dried leaves of the Morus alba tree, a plant long valued in both Chinese medicine and sericulture (silk farming). In TCM, mulberry leaf is classified as sweet, bitter, and cold, entering the Lung and Liver meridians. Traditionally, it is used to clear Lung heat, cool the blood, moisten dryness, and calm the Liver. Its versatility makes it a key herb for treating respiratory illnesses, eye problems, and skin conditions caused by internal heat.
