How does Quillaia work?

Quillaia contains high concentrations of tannins. Astringent chemicals, such as tannins, can thin mucous to make it easier to cough up. Quillaia also contains a chemical which may help stimulate the immune system.

Are there safety concerns?

Quillaia doesn't appear to be safe when taken by mouth in medicinal doses. Plants such as quillaia that contain high amounts of tannins can cause stomach and intestinal disturbances, and kidney and liver damage. Quillaia also contains chemicals called oxalates that can lower blood calcium levels and cause kidney stones. Quillaia use is also associated with diarrhea, stomach pain, serious breathing problems, convulsions, coma, red blood cell destruction, and kidney failure. It can also irritate and damage the lining of the mouth, throat, and digestive tract.

It is not known if quillaia is safe when used on the skin or in the vagina. If inhaled, the powder can cause sneezing.

While quillaia probably isn't safe for anyone to take, some people should be especially careful to avoid use.

Do not take quillaia if:
  • You are pregnant or breast-feeding.
  • You have kidney disease.
  • You have stomach or intestinal disorders or diseases.
