Infection is one of the complications that often occur during postpartum period, which can be caused by improper perineal wound care. Therefore, it is extremely necessary to treat perineal wounds properly. The purpose of this study is to determine the effect of processed Kersen (Muntingia Calabura L.) leaf products on perineal wound healing in postpartum mothers. The analysis applied a quasi-experimental method with the posttest-only control group design, in which there were a treatment group (intervention) consisting of postpartum mothers who drank processed Kersen leaf products and a control group containing postpartum mothers who did not receive any intervention. A total of 38 people were selected as respondents through purposive sampling. The REEDA scale was chosen as an instrument for assessing perineal wound healing. The obtained data was then analyzed using the Chi Square test. The results of the study showed that 19 people in the treatment group (100%) experienced a rapid healing process. Meanwhile, 6 people in the control group (31.6%) had a rapid healing process, whereas the remaining 13 people (68.4%) experienced a normal healing process. Furthermore, the results of the analysis using the Chi-Square test obtained p-value = 0.000 (p < 0.05), meaning that Ha is accepted. Therefore, it can be concluded that there is a significant effect of processed Kersen leaf products on perineal wound healing.
