Quillaja saponaria Soap-bark tree Evergreen tree (1 Page of 5) The Quillaja saponaria plant species is found in S. America - Chile, Peru. It is a member of the Rosaceae family. Common gardeners may know the plant as Soap-bark tree. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Quillaja saponaria Common Name: Soap-bark tree Family: Rosaceae Author: Molina. Known Hazards: The plant is toxic if taken internally, tending to dissolve the blood corpuscles[171].
The bark, and possibly other parts of the plant, contains saponins[4]. Although toxic, saponins are very poorly absorbed by the body and so tend to pass through without causing harm, they are also destroyed by thorough cooking. Saponins are found in many plants, including several that are often used for food, such as certain beans. It is advisible not to eat large quantities of food that contain saponins. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish[K]. Mature Height: 18 Mature Width: 6 Habitat: Mountainous regions on the western slopes of the Andes[169, 171].
General Uses: The fresh or dried inner bark is a soap substitute[4, 169, 171]. It contains about 9% saponins and is a very gentle and effective cleaner[169, 171]. It is used for cleaning textiles and the skin[1, 46, 169, 171]. It can also be used as a hair tonic[169, 171]. The saponins are also used in anti-dandruff shampoos and exfoliant cleansers[238]. They are used as a foaming agent in fire extinguishers[238].
The bark also contains considerable quantities of carbonate of lime[1].
