<![CDATA[Nausea and vomiting are among the most common complaints experienced by pregnant women during the first trimester, and if left untreated, may progress into hyperemesis gravidarum. This study aims to determine the effect of lemon suanggi (Citrus hystrix) inhalation on nausea and vomiting among first-trimester pregnant women at RSAU dr. Charles P.J. Suoth Manado City. A quantitative approach was employed using a quasi-experimental design with a one group pretest-posttest model. The population consisted of all first-trimester pregnant women visiting the hospital, with a sample of 30 respondents selected through purposive sampling. Data were collected using observation sheets covering respondent characteristics, frequency of lemon inhalation, and nausea-vomiting response, then analyzed using Chi-Square and Spearman correlation tests. The results revealed a significant relationship between lemon suanggi administration and the reduction of nausea-vomiting response (p=0.000), as well as between administration frequency and symptom improvement (p=0.003). Spearman correlation showed a strong negative relationship between lemon administration and nausea-vomiting response (r=-0.837), indicating that more consistent inhalation was associated with greater symptom reduction. These findings imply that lemon suanggi inhalation can serve as a safe, accessible, and effective non-pharmacological intervention to alleviate nausea and vomiting in early pregnancy, supporting its integration into routine antenatal care practices.]]>
