Action Bark—cutaneous stimulant. Its liquid extract is used as a lotion for certain skin diseases of the scalp, and in antiulcer preparations.
The detergent and medicinal properties of quillaia are due to the presence ofhaemolytic saponins (9—10%) of which quillaia-saponin (which yields glucuronic acid and quillaic acid, a sapogenin, on hydrolysis) is most important.
Quillaja extracts caused marked swelling and haemorrhage in stomach and small intestines of mice after 24 hours.
An isolated saponin (QS-21) from the bark shows evidence that it might augment both antibody and cell-mediated immune response, significantly increasing antibody levels. (Natural Medicines Comprehensive Database, 2007.)
