Most respondents reported no side effects (63.8%), whereas mild and moderate side effects were reported by 26.7% and 9.5% of respondents, respectively. Maternal age was significantly associated with herbal medicine consumption patterns (p = 0.014). However, no statistically significant association was observed between herbal medicine consumption patterns and reported side effects (p = 0.068).Conclusion: Maternal age was significantly associated with herbal medicine consumption patterns among women who had been pregnant within the previous 1-2 years. However, no statistically significant association was observed with reported side effects.
