SIDE EFFECTS
Herbal medicines are really becoming popular, but many people who use them don't think they need to tell their doctors because we constantly hear the phrase "not a drug, so you don't need a prescription" attached to these herbal concoctions. This can cause problems when some of the herbs are mixed with each other or prescription drugs!

Chamomile: Do not use if pregnant or nursing. Contains coumarin, but chamomile's effects on the body's anticoagulation system have not been studied. If used with anticoagulants such as warfarin, close monitoring by a doctor is advised.

Echinacea: May be toxic to the liver if used for more than eight weeks. Should not be used with drugs that can cause liver problems, such as anabolic steroids, amiodarone, methotrexate and ketoconazole. Should not be given with immunosuppressants such as corticosteroids and cyclosporine because it can stimulate the immune system.

 

Evening primrose oil and borage: Should not be used with anticonvulsants because they may lower the seizure threshold.

Feverfew: Effect on migraine headaches may be compromised by nonsteroidal anti-inflammatory drugs, such as aspirin and ibuprofen. Also should not be used with the drug warfarin or other anticoagulants because feverfew inhibits clotting.

Garlic: Should not be used with warfarin because it affects clotting.

Ginger: Should not be used with warfarin because it affects clotting.
