Background

Carqueja is an herb. People dry the parts of the plant that grow above the ground and use them to make medicine.

People use carqueja for many conditions, but there is no scientific evidence to support these uses.
When taken by mouth: There isn't enough reliable information to know if carqueja is safe or what the side effects might be.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if carqueja is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

Allergy to ragweed, daisies, and related plants: Carqueja may cause an allergic reaction in people who are sensitive to the Asteraceae/Compositae plant family. Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many others. If you have allergies, be sure to check with your healthcare provider before taking carqueja.

Diabetes: Carqueja might lower blood sugar levels. Using carqueja along with diabetes medications might make blood sugar levels drop too low. Monitor blood sugar levels closely.

Surgery: Carqueja might affect blood glucose levels. There is some concern that it might interfere with blood sugar control during and after surgery. Stop using carqueja at least 2 weeks before a scheduled surgery.
