According to a study published by "PloS one", Litsea glutinosa leaves demonstrate significant analgesic, antipyretic, and antibacterial activities. In the hot plate method, a 500 mg/kg dose of the crude extract produced a pain inhibitory activity of 3.37 ± 0.31 sec, which differed significantly (P < 0.01 and P < 0.001) from morphine's 6.47 ± 0.23 sec. The 500 mg/kg dose also achieved a 70% suppression of writhing in mice (p < 0.001) compared to the 77.5% inhibition from morphine. Regarding antipyretic activity, the crude extract at 300 mg/kg-body weight reduced body temperature to 36.17 ± 0.32 °C after 3 h, while the standard at 100 mg/kg-body weight resulted in 36.32 ± 0.67 °C. Furthermore, a 400 μg dose of each extract inhibited bacterial growth within zones of 11 to 22 mm.
