Myrtus communis L. belongs to the family Myrtaceae and is commonly found in the Lower District, Swat. A survey reported that Myrtus communis is traditionally used for medicinal and cultural purposes. Local residents provided information about local uses, recipe preparation, and diseases treated, which were recorded. The primary aim of the study was to understand the cultural and ethnomedicinal uses of this species in the study area. Data were collected from 311 informants across eleven localities in Lower Swat: Islamphur (Balavo), Shagai (Ghwara Khela Batorda), Shagai (Shne Shah), Marghazar (Daba Tangai), Marghazar (Manrvano Dub), Barikot (Natmera), Barikot (Nawagai), Barikot (Qwanj), Amlokdara (Gorykan), Jambeel (Shagai), Jambeel (Jhelkanai), and Kokarai (Lokmera/Chamanr). The overarching goal was to involve all participants in gathering information on the medicinal uses and importance of Myrtus communis. It is noted that various parts of this species (i.e., leaves, fruits, flowers, stem, and whole plant) are used in cultural practices and to cure different diseases (Figure). Culturally, this species is used for tea (n=49), as a flavoring agent (n=17), and as food (n=17) (Figure). Ethnopharmacologically, it is used to cure chest disorders (n=39), headaches (n=32), hypertension (n=31), diabetes (n=28), stomach issues (n=25), gastric ulcers (n=22), diarrhea (n=16), and tooth pain (n=15) (Figure). The highest Relative Popularity Level (RPL), i.e., 1.00, is noted for the following cultural uses and diseases: diabetes, stomach issues, gastric ulcers, headaches, chest disorders, hypertension, and tea. The lowest RPL (i.e., 0.14) was noted for anthelmintic and anxiety. The highest Rank Order Priority (ROP) is noted for tea (ROP=15.8), while the ROP for other cultural uses is food (ROP=4.68) and flavoring agents (ROP=4.49).
