Cassava (Tapioka)

Cassava (Tapioka)

Manihot esculenta (Euphorbiaceae)


Woody shrub. Although naturally a perennial plant, Cassava is extensively cultivated as an annual for its edible starchy tuberous root, a major source of carbohydrates. Though it is often called “yuca” in Spanish America and in the United States, it is not related to “yucca”, a shrub in the family Asparagaceae.

Before consumption, it must be properly prepared, as improper preparation can leave enough residual cyanide to cause cyanide intoxication.


Native to South America. Cultivated around the world in tropical and subtropical regions.

Natural Medical Properties

Cassava is often used in traditional medicine and has several applications.
The plant is antifungal, antiviral, mutagenic and antibacterial.
The roots of bitter varieties can be used to treat scabies, diarrhoea and dysentery.
The juice of the grated tubers is used to treat constipation and indigestion.
A flour made from the roots can be used as a dusting powder on the skin in order to help dry weeping skin.
Soaked with Carapa oil, it is used as a poultice on shattered muscles.
It is mixed with rum and rubbed onto children’s skin as a treatment for abscesses and skin eruptions.
It can be made into an ointment to treat fungal dermatitis.
