Perceptions and use of traditional medicine/Centella Asiatica (Rau Ma) for cancer treatment in Vietnam: A quantitative survey study

This study investigates the public’s perceptions and practices regarding the use of Centella asiatica ( C. asiatica ), known locally as Rau Má, and potential as a cross-over drug for liver cancer, in Vietnam. The research employs a quantitative survey conducted across two major cities, Hanoi and Hue, to assess knowledge, attitudes, beliefs, and practices surrounding traditional medicine and its integration with modern healthcare, particularly in cancer treatment. A total of 804 participants were surveyed using a multistage stratified random sampling technique, ensuring a diverse representation across socio-economic backgrounds, ages, and urban/rural settings. Results reveal widespread awareness of C. asiatica , with significant socio-economic and regional differences in perceptions and acceptance of traditional remedies. Most participants, especially those from rural or lower socio-economic backgrounds, view treatment using derivatives of C. asiatica as a viable complementary therapy for liver cancer, with many expressing a preference for combining traditional medicine with conventional cancer therapies. The study highlights the potential for integrating traditional remedies like C. asiatica into modern healthcare practices and suggests further research to validate its efficacy and safety in cancer care.
