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 that may help stimulate the immune system.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
Quillaia seems to be safe when taken in food amounts. But it might be UNSAFE 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 can also cause diarrhea, stomach pain, serious breathing problems, convulsions, coma, red blood cell destruction, and kidney failure. Quillaia can also irritate and damage the lining of the mouth, throat, and digestive tract.
It is not known if quillaia is safe when put on the skin or in the vagina. If inhaled, the powder can cause sneezing.
Pregnancy and breast-feeding: Quillaia might be UNSAFE for both mother and infant. Avoid use.
Stomach and intestinal (gastrointestinal, GI) problems: Quillaia can irritate the GI tract. Don't use it if you have a stomach or intestinal disorder.
Kidney disease: The oxalate in quillaia can cause kidney stones. Don't use it if you have kidney disease or a history of kidney stones.
Medications taken by mouth (Oral drugs)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.
Quillaia contains a large amount of chemicals called tannins. Tannins absorb substances in the stomach and intestines. Taking quillaia along with medications taken by mouth can decrease how much medicine your body absorbs, and decrease the effectiveness of your medicine. To prevent this interaction, take quillaia at least one hour after medications you take by mouth.
Metformin (Glucophage)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.
Metformin (Glucophage) is used to help decrease blood sugar. Quillaia might decrease how much metformin (Glucophage) the body absorbs. Taking quillaia along with metformin (Glucophage) might decrease the effectiveness of metformin (Glucophage) for lowering blood sugar. Monitor your blood sugar closely. The dose of your metformin (Glucophage) might need to be changed.
The appropriate dose of quillaia depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for quillaia. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
