The invention discloses a rhizoma bletillae extract and application thereof. The rhizoma bletillae extract is prepared by the following steps: carrying out backflow extraction on dried rhizoma bletillae powder with a 60-90% ethanol solution, filtering, and collecting filtrate so as to obtain a rhizoma bletillae alcohol extract; adsorbing the rhizoma bletillae extract with polyamide and a D101 macroporous resin in sequence, collecting a 35-45% ethanol eluant, and carrying out vacuum evaporation drying, thereby obtaining the rhizoma bletillae extract. In-vivo SD (Sprague Dawley) rat chronic bronchitis mode experiments show that rhizoma bletillae and an effective part EFB have a treatment function on chronic bronchitis by inhibiting inflammatory factors such as TNF-alpha, IL-1 beta and IL-6,and by increasing oxidation stress levels.
