Premna, Cây Lá Cách

Premna serratifolia – medicinal valuable tree.

Native to Australia, India and much of Asia.

Headache Tree – most widely used, from its folk use in treating headaches.

Coastal Premna – used in botanic gardens and landscaping references.

False Elder – occasional name, since its foliage resembles elder (Sambucus).

Black Premna – sometimes used because of its dark berries.

Premna serratifolia is a hardy, large spreading shrub with attractive glossy, leathery leaves. In summer it produces showy clusters of cream-white flowers, followed by shiny black berries that attract birds and wildlife. An excellent choice for tropical and subtropical gardens, it provides shade, habitat, and year-round greenery.

Cooking Uses

In Vietnam, the leaves are a must-have for stir-fries. They are often thinly sliced and cooked with beef, eel, or frog. The leaves help take away any strong gamey smells from the meat.

You can also use the fresh leaves as a wrap. They work well for wrapping grilled meats or pancakes, similar to how you would use betel leaves. They have a slightly bitter but pleasant taste that cleanses the palate.

Health Benefits

The leaves are known for helping with digestion. Many people eat them to help settle their stomach after a big meal. In traditional medicine, they are used to help clear heat from the body and support the liver.
