Sang Ye (Mulberry Leaf)

Sang Ye is also known as Folium Mori and is the leaf of Mulberry, which is a deciduous tree belonging to Moraceae. It is the main food of silkworm.

Mulberry is an economic plant and originated in China, which is now mainly distributed in some countries in Asia and Europe.

The Chinese have a tradition of planting mulberry trees. They believe that mulberry represents their hometown. Its trunk can be made into furniture or musical instruments, and its branches can be woven into baskets. Its bark can be used to make paper, and its fruits can be eaten or made into wine.

After the first frost of each year, people gather mulberry leaves, remove their impurities, dry them in the sun, remove their petioles, and make them into Chinese herbs.
