A synergistic mechanism of Liquiritin and Licochalcone B from Glycyrrhiza uralensis against COPD

Chronic Obstructive Pulmonary Disease (COPD) is a refractory respiratory disease mainly attributed to multiple pathological factors such as oxidative stress, infectious inflammation, and idiopathic fibrosis for decades. The medicinal plant Glycyrrhiza uralensis extract (ULE) was widely used to control respiratory diseases in China. However, the regulatory mechanism of scientific evidence to support the therapeutic benefits of ULE in the management of COPD is greatly limited.
