Probiotics. Probiotics are beneficial bacteria that may help protect against allergies and asthma. Antibiotic over-use and modern hygiene may specifically be reducing these helpful organisms. Probiotics can be obtained in active yogurt cultures and in supplements, which are being studied for protection.
Herbal Remedies. Herbal remedies have been used with apparent success in Eastern nations, but few have been studied rigorously in the United States. Butterbur (also known as Petasites hybridus, butter dock, blatterdock, bog rhubarb, and exwort), a traditional herbal remedy, is used for seasonal allergies and asthma. In a 2002 study, it was as effective and less sedating than a commonly prescribed antihistamine for treating seasonal allergies over a 2-week period. More research is needed. Even when natural remedies appear to be effective in trials, there are no standards or regulations in the U.S. to guarantee their quality, effectiveness, or safety. Of great concern are their growing use and the possibilities of serious drug interactions. Patients who try alternative treatments should be sure to inform their doctor.
