Acanthus Ebracteatus Tea Acanthus-ebracteatus-400

We stumbled upon this product in some alternative medicine stores in Southern Thailand. MAP-Indonesia has developed a solar drying hut for use in drying the leaves to a consistent humidity.

Acanthus ilicifolius tea is a general tonic, and is safe to drink every day. It is best served like green tea, without sugar or other sweeteners. It is also best not to come in contact with metal (such as spoons) or some of the medicinal qualities may be lost.

The tea is an antioxidant and is used traditionally as an anti-allergen, for boil treatment of boils or abĀ­scesses, to guard against infection and to expel kidney stones.


-97% Holly mangrove (Acanthus Ebracteatus) leaves

-3% Pandan (Pandanus amaryllifolius) leaves


Cut thorns off of the leaves.  Dry in sun with the Pandan leaves.  Chop leaves into fine pieces or grind. Continuing drying under controlled conditions if possible. 

Serve like green tea.

We use a solar dryer which is a solar heating plate attached to a drying house made of bamboo with strategic ventilation to ensure consistent internal temperature and humidity.

The solar heating plate can be made of a corrugated iron sheet in a plywood box with a glass cover.  The iron sheet is covered with a wire mesh on the upper surface and painted black.  The solar panel is connected to the small hut with a pipe.  Racks are built into the hut with holes allowing for even air flow.  Two exhaust chimneys are built into the roof.


These plants have no relation whatsoever with the Christmas Holly, although they appear similar.
In fact, not all the leaves have the spiny edges that give them their common name. Leaves growing the deep shade can be totally spineless.
Unlike some mangrove plants, Sea Holly do not exclude salt at the root level. In fact, their sap is salty and excess salt is secreted through the leaves, to be removed by rain or wind. Sometimes, the salt can be seen as a white crystalline layer on the upper surface.
The plant produces a cluster of flowers that develop into pods. When the pods ripen, they explode to propel the seeds up to 2m away.
Sea Holly grows on mud near the hide tide mark, often on mud lobster mounds. It can grow equally well under trees and in open areas. But it grows especially well in areas with more freshwater input. The plant can sometimes cover large areas and form thickets, particularly in disturbed mangrove. They also grow along river banks.
Uses: In Indonesia, the entire plant is placed in rice sacks to keep the rice dry (i.e., acts as a desiccant).
Traditional medicinal uses: The leaves of A. ilicifolius are used to treat rheumatism, neuralgia and poison arrow wounds (Malaysia). It is widely believed among mangrove dwellers that chewing the leaves will protect against snake bite. The pounded seeds are used to treat boils, the juice of leaves to prevent hair loss and the leaves themselves to ward off evil (Malay). Both species are also used to treat kidney stones. The whole plant is boiled in fresh water, and the patient drinks the solution instead of water, half a glass at a time, until the signs and symptoms disappear (Thailand). Water extracted from the bark is used to treat colds and skin allergies. Ground fresh bark is used as an antiseptic. Tea brewed from the leaves relieves pain and purifies the blood (widespread in both the Old and New World).
