What is mancae?

Mancae, also known as "mulberry galls," are small, hard, bulbous growths that are found on the leaves and twigs of certain species of mulberry trees. They are caused by a tiny insect called the gall mite, which feeds on the tree's tissues and stimulates the growth of the gall as a protective cover.

Mancae are typically about the size of a pea and range in color from light green to reddish brown. They have a tough outer shell and may contain a small cavity in the center where the mite is found. Mancae are often used in traditional medicine and are believed to have anti-inflammatory and anti-cancer properties, although more research is needed on their potential benefits.

In addition to mulberry trees, mancae may also be found on other plants such as oaks, willows, and roses, and each species of gall has its own unique shape and appearance. While mancae are not harmful to the tree and are generally considered harmless to humans and animals, they can be unsightly and may cause some minor damage to the affected foliage.
