Herbal Butterbur may have a potential effect in reducing the airway hyperresponsiveness, one of 2 key pathophysiological features of asthma, some scientists found.
Airway hyperresponsiveness is a condition by an abnormal response of the airways to nonspecific stimuli, which results in airway obstruction.
At the final report of the experiment, the researcher wrote, " all patients with asthma persisting but not necessarily current symptoms of asthma have increased AHR,, which satisfies a proposed epidemiologic definition of asthma".
Butterbur, found in wet, marshy, damp land, including wetland, Riverside, forest, etc., is a creeping underground plant, genus Petasites of 15 -20 species, belonging to the family Asteraceae, native to Northern Hemisphere.
It has been used in herbal medicine used as a pain reliever in the digestive system, including stomach, bile ducts, and duodenum, etc.
The chemical constituents of Butterbur include Petioles, petasitene, and ethylene, quercetin 3-O-beta-D-glucoside, quercetin 3-O-beta-D-6''-O-acetylglucoside, and rutin, caffeic acid, alkaloids, S-petasin and iso-S-petasin, etc.
On finding a natural remedy for the treatment of asthma with no side effects, researchers examined the effect of herbal Petasites hybridus (butterbur) extract (Ze 339, PET) in the murine model of allergic airway disease (asthma).
Taken altogether, herbal Butterbur may be considered a functional herb for the prevention and combined with other primary therapy for the treatment of asthma with no side effects.
