Side Effects of Slippery Elm

According to the University of Maryland Medical Center, ulmus fulva, also known as slippery elm, contains a substance called mucilage that turns into a slick gel when it is mixed with water. This gel reportedly soothes and coats the stomach, intestines, throat and mouth when used.

Benefits

• Slippery elm is also believed to have antioxidant properties that relieve irritable bowel issues. Slippery elm was first used by Native Americans as a salve for ulcers, burns, boils, wounds and other types of skin inflammation. When taken orally, it relieves sore throats, stomach problems, coughs and diarrhea.

Considerations

• There hasn't been a lot of research done on the efficacy or safety of slippery elm, according to the University of Maryland Medical Center. However, those studies that have been done conclude that there are no serious side effects. However, slippery elm may interact with other herbs and drugs that you are taking, so you must take this into consideration before using it. Because slippery elm coats the digestive tract, it may slow down the absorption of other drugs and herbs. It is advised that an individual take slippery elm two hours before, or after, taking any other herbs or medication. And, as noted above, allergic reactions can occur and, although perhaps not life-threatening, they may cause great discomfort.

Avoid if Pregnant or Nursing

• If you are pregnant or nursing, be extremely cautious regarding what you ingest. Slippery elm is considered to be safe during pregnancy and while breastfeeding but, since very limited research has been done on the side effects of slippery elm, err on the side of caution and do not take it during pregnancy or while nursing. In fact, it is possible that the substances contained in the outer bark of the elm tree can increase the risk of miscarriage, according to the University of Maryland Medical Center, so play it safe and avoid slippery elm while pregnant.

Possible Contamination

• The Web site www.drugs.com warns that since slippery elm has yet to be evaluated by the FDA regarding its effectiveness, purity and safety, there may be unknown potential harm and risks associated with slippery elm. Since this product is not regulated, there is a chance that it could be contaminated with other drugs or toxic metals. Make sure that you purchase your herbs from a reliable agent.

Allergic Reactions

• Some possible allergic reactions reaction to slippery elm, according to www.pdrhealth.com, include swelling in the hands or face; tingling or swelling in the throat or mouth; hives, itching, chest tightness and difficulty breathing.
