Quillaia (Quillaja saponaria) is a large evergreen tree found in Peru and Chile. Chemicals in the tree bark called saponins act as natural detergents.
Saponins can attach to dietary fat in the stomach. This might help lower cholesterol. Quillaia also contains high concentrations of chemicals called tannins. Tannins can thin mucus to make it easier to cough up.
People use quillaia for asthma, high cholesterol, bronchitis, and many other conditions, but there is no good scientific evidence to support these uses. .
When taken by mouth: Quillaia is commonly consumed in foods. But it is possibly unsafe when used in larger amounts as medicine. Quillaia contains high amounts of tannins which can cause stomach problems, as well as kidney and liver damage. Quillaia also contains chemicals called oxalates, which can cause kidney stones.
When applied to the skin: There isn't enough reliable information to know if quillaia is safe or what the side effects might be.
