Special Precautions & Warnings

Pregnancy and breast-feeding: Bridelia is LIKELY UNSAFE when used during pregnancy. There is concern that Bridelia might stimulate the uterus and cause labor. Avoid using.

Not enough is known about the use of Bridelia during breast-feeding. Stay on the safe side and avoid use.

Bleeding disorders: Bridelia might slow blood clotting. This might increase the risk of bleeding or bruising in people with bleeding disorders.

Hormone-sensitive conditions such as breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids: Bridelia might have the same effects as the female hormone estrogen. If you have any condition that might be made worse by exposure to estrogen, don't use Bridelia.

Low blood pressure: Bridelia might decrease blood pressure. Don't take Bridelia if you already have low blood pressure.

Surgery: Bridelia might slow blood clotting. In theory, Bridelia might cause extra bleeding or affect blood pressure control during and after surgery. Stop using it at least 2 weeks before a scheduled surgery.


EstrogensInteraction Rating: Moderate Be cautious with this combination.Talk with your health provider.

Bridelia might have some of the same effects as estrogen. However, Bridelia is not as strong as estrogen pills. Taking Bridelia along with estrogen pills might decrease the effects of estrogen pills.

Some estrogen pills include conjugated equine estrogens (Premarin), ethinyl estradiol, estradiol, and others.

Medications for high blood pressure (Antihypertensive drugs)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.

Bridelia might lower blood pressure. Taking Bridelia along with medications for high blood pressure might cause your blood pressure to go too low.

Some medications for high blood pressure include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), Amlodipine (Norvasc), hydrochlorothiazide (HydroDiuril), furosemide (Lasix), and many others.

Medications that slow blood clotting (Anticoagulant / Antiplatelet drugs)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.

Bridelia might slow blood clotting. Taking Bridelia along with medications that also slow clotting might increase the chances of bruising and bleeding.

Some medications that slow blood clotting include aspirin, clopidogrel (Plavix), diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.


The appropriate dose of Bridelia 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 Bridelia. 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.
