The Most Valuable Herb for Allergy Season

This systematic review of studies on herbal solutions for allergies concluded that butterbur is the most researched allergy herb. It also found that it works. . . . 

Three out of four placebo-controlled studies found it to be effective. The review also found that two studies comparing it to non-sedating antihistamines found it to have similar effects.
   Actually, the herb had equal effects and was even the more desirable treatment because in at least one of the drug comparison studies, the herb had fewer side effects.
