Xiaoqinglong decoction attenuates inflammatory response and mitochondrial injury by regulating the MyD88/NF-κB pathway dependent of TLR4 in allergic rhinitis.

Background: Allergic rhinitis (AR) is a systemic immune inflammatory response disease of the nasal mucosa. Current treatment strategies for AR are limited owing to a lack of safety and the inability to cure the condition completely. Xiaoqinglong decoction (XQLD), a classical chinese medicine prescription, is widely used to treat AR with a good curative effect.
