(Integrative Medicine) - People who suffer from seasonal allergies may breathe easier with butterbur, according to a new study published in the British Medical Journal.

Researchers in Switzerland report that butterbur, an herb from the same plant family as echinacea, may be as effective as some leading antihistamines but with fewer side effects. One-hundred twenty-five people with hay fever were randomly assigned to receive butterbur or cetirizine (a commonly used antihistamine) for two weeks. At the end of the study period, participants from both groups demonstrated a similar improvement in symptoms. Interestingly, although cetirizine is considered a non-sedating medication, participants who received this medication reported having more sedative side effects (such as drowsiness and fatigue) than those in the butterbur group.

"We believe butterbur should be considered for treating [hay fever], particularly in cases where the sedative effects of antihistamines need to be avoided," the researchers conclude.
