Medicinal plants in Cambodia have been used traditionally to treat various ailments such as backache, burn, cold, cough, diarrhea, headache, malaria, post-partum, sprain, stomachache and wound. This survey aimed at conducting the ethnobotanical observation on medicinal plants used by traditional healers in Kampong Speu province, Cambodia. The survey was administered at Odonk District, Kampong Speu Province, Cambodia. The ethnobotanical data were  
obtained using a semi‑structured questionnaire method. The questionnaire was used to interview 8 respondents who were considered as local traditional healers. It was observed that the traditional healers used 50 species of medicinal plants. These plants were distributed amongst 25 families, the most of which belong to Fabaceae (24.0%; n = 6), Poaceae (16.0%; n = 4); Lamiaceae (16.0%; n = 4), Zingiberaceae (16.0%; n = 4), Menispermaceae (12.0%; n = 3), Phyllanthaceae (12.0%; n = 3), Rubiaceae (12.0%; n = 3) and Sapindaceae (12.0%; n = 3). The most frequently used plant’s parts were stems (43.14%; n = 44), roots (21.57%; n = 22), whole plant (11.76%; n = 12) and barks (9.80%; n = 10). The medication was prepared as decoction (82.35%; n = 28) and maceration (17.65%; n = 15).  
Mostly, the plants were administered through oral (96.47%; n = 82) route. The reported plants are used to manage mainly such conditions as post-partum, hemorrhoids, gastroenteritis and syphilis accounted for 14.12% (n = 12), 10.59% (n = 9), 9.41% (n = 8) and 9.41% (n = 8) respectively. This study provides the documentation of the medicinal plants used by the traditional healers treat the regional dwellers living in Kampong Speu province, Cambodia.
