The Powerful White Mulberry Leaf

A Well Known Berry, A Mysterious Leaf

Most people are familiar with mulberries in some form. Be it a delicious fruit or an easy and sweet preserve, many know some strain of this berry.

But, one type of mulberry tree may deserve more appreciation as a medicinal herb. Yet, this herb is not derived from the berry- but from the leaves! White mulberry leaf is full of nutritional components that help to support health.

Common Uses for an Uncommon Herb

White mulberry leaves are best known as the primary food source of the silkworm. This tree was especially important in China, as silk was one of their most valuable exports. It’s thought that silkworms eat white mulberry leaves due to their unique scent.

The silkworms are then able to convert proteins in the leaves into silk. Thus, silk is made of nothing more than white mulberry leaves. However, these leaves were more than just silkworm food to the ancient Chinese. Traditional Chinese Medicine also valued the herb for its many health-supporting properties.

The sole food source of the silkworm is white mulberry leaves.

Historical Use of White Mulberry Leaf

White mulberry trees are native to China. They have been used medicinally there since ancient times. White mulberry is now cultivated in many regions such as the United States, Africa, and Europe. In fact, these trees have been long revered in many cultures. Often white mulberry tree were brought to new regions due to their popularity with silkworms.

Mulberry Trees in Britain

When the Romans invaded Britain, they brought mulberry trees with them. The leaves served medicinal purposes, such as treating diseases of the mouth and lungs. Henry VIII even had a Mulberry tree planted in his Chelsea estate. Later, King James I decided that Britain should compete with France in silk-making.

King James attempted to make silk Britain’s main export by bringing over mulberry trees, the food source of the silkworm.


In order to accomplish this, he brought over ten thousand mulberry trees to feed the silkworms, planting some in a garden near Buckingham Palace. Yet, this project ultimately failed as he brought the wrong kind of mulberry tree. He had failed to bring the powerful white mulberry tree, with its nutritional leaves.

White Mulberry in the United States

The British introduced white mulberry to North America before the American Revolution. White mulberry was first brought to America in a failed attempt to establish a silkworm industry. Since then, several varieties of this tree have spread through North America. In fact, now most counties in Ohio have some white mulberry trees. Often, they grow in unattended areas and open rural habitats.
