Fitoterapia. Jan 2014. Anti-inflammatory activity of sulfate-containing phenolic compounds isolated from the leaves of Myrica rubra.

Plant Foods Hum Nutr. 2013. Biological activities of extracts from Chinese bayberry (Myrica rubra Sieb. et Zucc.): a review. Chinese bayberry (Myrica rubra Sieb. et Zucc.) is a subtropical fruit tree native to China and other Asian countries, and culture of this Myricaceae plant has been recorded in Chinese history for more than 2000 years. Bayberry fruit is delicious with attractive color, flavor, and high economic value. Compared with other berries, bayberry fruit is a rich source of cyanidin-3-glucoside, which accounts for at least 85 % of the anthocyanins in the fruit. Bayberry is also a plant with high medicinal value since different organs have been used historically as folk medicines. Research efforts suggest bayberry extracts contain antioxidants that exhibit bioactivities counteracting inflammation, allergens, diabetes, cancer, bacterial infection, diarrhea and other health issues.
