Paeonia emodi is used in traditional medicine in its home range to treat amongst others diarrhoea, high blood pressure, congestive heart failure, palpitation, asthma and arteriosclerosis. The parts of this plant contain chemical compounds such as triterpenes, monoterpene glucosides and phenols. Extract of the root stabilises heart beat rates, relaxes the airways and reduces blood clotting. Paeoninol and paeonin C from the fruit inhibit lipoxygenase, an enzyme that produces substances associated with asthma, inflammation, and the growth of bloodvessels in tumors. Paeoninol and paeonin C are active as antioxidant. Research illustrated that an ethanol extract of P. emodi suppressed the growth of common duckweed (50% at 50μg/ml), and was moderately effective in killing some insects (red flour beetle). No inhibition of the growth of bacteria and fungi could be demonstrated, and no general toxicity was observed in brine shrimps, suggesting it may be safe to use.
