Myrtus communis is a traditional medicinal aromatic plant in the Mediterranean. At present, the plant has been introduced and cultivated in the southern part of China, and it is mostly used for ornamental or cosmetic purposes. Based on literature analysis and the theory of Chinese medicine, we discussed the medicinal parts and properties of M. communis in this paper to provide a theoretical basis for exploring the medicinal value of M. communis and its compatibility with traditional Chinese medicines. Literatures were searched from Web of Science(core collection), PubMed, CNKI, VIP and Wanfang by using the set conditions as key words. Then the obtained literatures were screened and classified. Finally, a total of 376 articles were included, consisting of 44 reviews, 54 germplasm resources, 78 chemical researches, 48 studies on application, extraction, or quality, 18 human trials, 132 pharmacological studies, and 2 safety studies. Based on literature analysis and theories of Chinese medicine, the leaves of M. communis were finally selected as the medicinal part of Chinese medicine, and the traditional Chinese medicine properties of M. communis leaves were deduced as pungent, bitter, and cool.
