Research articles related to Litsea chinensis:
Analgesic activity: The present study was designed to evaluate analgesic potential of the ethanolic extract of the bark of the plant. The extract, at the dose of 100 and 300 mg/ Kg, has shown a significant (p<0.05) increase in pain threshold in hotplate, as compared with control group.

Anti- nociceptive property: Antinociceptive property of leaves extract of Litsea glutinosa was evaluated by abdominal writhing and tail flick methods using mice. Ethanol extract of leaves was tested at three different concentrations 100 mg/kg, 200 mg/kg and 300 mg/kg body weight orally. Results showed that, among three different dosages, dosage of 300mg/kg (65%) significantly inhibited the nociception induced by acetic acid when compared to dosage of 100 mg/kg (36.64%) and 200 mg/kg (52.79%).

Anti- pyretic and anti- inflammatory action: The study was conducted to evaluate the in vitro thrombolytic activity, and in vivo analgesic, anti-inflammatory and antipyretic potentials of different hydrocarbon soluble extracts of Litsea glutinosa leaves. Our results yield that the crude hydroalcoholic extract has better effects than the other in all trials. In the context, it can be said that the leaves of L. glutinosa possess remarkable pharmacological effects, and justify its traditional use as analgesic, antipyretic, anti-inflammatory, and thrombolytic agent.
