Flavonoids and phenolic acids are the main medicinal components of it ，especially three monomers have a wide range of efficacy and have been studied more ，such as orientin ，vitexin and 2″-O-galactopyranosyl orientin. T. chinensis is mostly used in clinical practice in the form of Chinese patent medicines ，such as Jinlianhua granules ，Jinlianhua capsules ， Jinlianhua tablets and Jinlianhua oral liquid. These medicines are used to treatment of upper respiratory tract infection ，pharyngitis， tonsillitis，periodontitis，mumps，oral ulcer ，and hand-foot-mouth disease.
