RosemaryNatural health supplements sometimes have unexpected side effects or interactions with medication that can lead to adverse reactions that are sometimes life threatening. The following is a list of cautions that you should be aware of before using rosemary (Rosmarinus officinalis). These are referred to as drug/herb interactions.
Warning 1 - Contraindications: Pregnancy, high blood pressure, epilepsy, ulcers, Crohn's disease, and ulcerative colitis. Rosemary oil can be toxic if ingested, and should never be taken orally.
Warning 2 - Anticoagulants: Rosemary may increase bleeding when used concurrently with anticoagulants. Be sure to consult your doctor if you are taking any blood-thinning drugs such as Plavix, Coumadin, or Aspirin.
Warning 3 - ACE inhibitors: Rosemary may interfere with the actions of ACE inhibitors such as Capoten, Monopril, Vasotec, Zestril, and other high blood pressure medications.
Warning 4 - Anemia: Research published in the "American Journal of Clinical Nutrition" (March 2001) revealed a link between rosemary's phenolic compounds and a decrease in the absorption of dietary iron. Therefore, it's not recommended that anyone with iron-deficiency anemia ingest rosemary oil. Topical preparations should be safe.
Warning 5 - Antidiabetics: Because rosemary affects blood sugar levels it could interfere with any drug taken to control diabetes.
Warning 6 - Antispasmodics: Rosemary might make seizure disorders worse. Experts recommend avoiding concurrent use.
Warning 7 - Diuretics: The University of Maryland Medical Center cautions that if rosemary causes the body to lose too much water, people taking lithium may see levels of the drug build up to toxic levels. Rosemary-induced water loss also can adversely affect patients taking furosemide (Lasix) or hydrocholorothiazide and the absorption of those drugs.
