Butterbur is a medicinal herb that has been used throughout history to treat asthma, cough, and wounds. In recent years, butterbur extract has been used to relieve allergy symptoms as well.
Feverfew is another herb that is effective against upper respiratory problems, including allergies, asthma and tinnitus. Generous amounts of Butterbur and Feverfew extracts can be found in Ultra Respiratory Pro Health, a natural supplement designed to relieve respiratory symptoms caused by colds and allergies.
