In a controlled trial, researchers divided Sprague Dawley rats into three groups: control (that received no treatment nor was subjected to any disease), COPD (in which rats displayed similar characteristics of human COPD patients), and treatment (which received various doses of bai bu extract). The rats were fed a similar diet for 112 days then were sacrificed.
Each rat’s lung function was tested and analyzed, with the right lower lung left fixed for morphologic observation. Inflammatory mediators in serum were observed using enzyme-linked immunosorbent assay.
It was found that rats that were given Radix Stemonae were able to keep their healthy weight compared to rats that had COPD. Further, bai bu improved pulmonary function in the rats, with the incidence of inflammation and emphysema being milder than in rats that had COPD.
Authors of the study concluded that a concentrated decoction of Radix Stemonae shows potential in mitigating COPD and improving airway rebuilding in the lungs of affected patients.
These results were published in BMC Complementary and Alternative Medicine.
Chronic lower respiratory disease (COPD) is the third leading cause of death in the United States, according to the Centers for Disease Control and Prevention (CDC). COPD describes a group of diseases that cause blockages in the airway and includes chronic bronchitis and emphysema.
Symptoms of COPD include shortness of breath, excess phlegm, mucus, or sputum, and frequent coughing or wheezing.
The CDC estimates that around 15.7 million (or around six percent) of Americans have been diagnosed with COPD; although this number might be higher. Roughly half of adults with low pulmonary function are not aware they have the disease.
Those most at risk are:
COPD may also be triggered by environmental pollutants, including room fresheners and herbicides. (Related: Study: Using Tylenol regularly can cause asthma and COPD.)
