<![CDATA[Sungkai (Peronema canescens) leaves are traditionally used in Indonesia to support general health and immune function; however, information on community perceptions and patterns of use remains limited. This study aimed to assess community perceptions of sungkai leaves as a traditional preparation for supporting immune health and to identify sociodemographic factors associated with regular use. An analytical cross-sectional survey was conducted from April to June 2025 among 240 adults in Banyumas, Cilacap, Purbalingga, and Banjarnegara Regencies, Central Java. Participants were recruited using purposive sampling. Data were collected through face-to-face interviews and Google Forms using a validated structured questionnaire and analyzed using descriptive statistics, chi-square tests, and multivariable binary logistic regression. Overall, 62.9% of respondents agreed or strongly agreed that sungkai leaf preparations may help support immune health, while 24.6% were neutral and 12.5% disagreed or strongly disagreed. A total of 136 respondents (56.7%) had used sungkai leaves, and 81 (59.6%) reported regular use in the previous month. Age, educational attainment, and domicile were significantly associated with regular use. Respondents aged >55 years had higher odds of regular use than those aged 18–35 years (adjusted odds ratio [aOR]=2.61, 95% CI=1.38–4.92). Rural residents (aOR=2.13, 95% CI=1.22–3.71) and respondents with primary or junior high school education (aOR=1.84, 95% CI=1.07–3.14) also had higher odds of regular use. In conclusion, communities generally view sungkai leaves positively as a traditional preparation that supports immune health. These findings reflect perceptions and reported use rather than clinical efficacy. Further pharmacological, toxicological, and clinical studies are needed to establish their safety and potential health effects.]]>
