Special Precautions & Warnings

Pregnancy and breast-feeding: Not enough is known about the use of brickellia during pregnancy and breast-feeding. Stay on the safe side and avoid use.

Diabetes: Developing research in animals suggests that some chemicals in brickellia might be able to lower blood sugar. There is a chance that brickellia might interfere with blood sugar control and might lower blood sugar too much. If you have diabetes and use brickellia, monitor your blood sugar carefully.

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


Medications for diabetes (Antidiabetes drugs)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.

Brickellia might decrease blood sugar in people with diabetes. Diabetes medications are also used to lower blood sugar. Taking brickellia along with diabetes medications might cause blood sugar to go too low. Monitor your blood sugar closely. The dose of your diabetes medication might need to be changed.

Some medications used for diabetes include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.


The appropriate dose of brickellia 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 brickellia. 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.
