A causal relationship model of herb use was created from observational data in this research, and the direct and indirect impacts of herb use on health were examined based on the model. The most vital factor influencing the use of herbal remedies is the level of social support perceived by an individual. Significant roles are also played by health literacy, positive attitudes toward herbal remedies, and societal values. Positive outlooks, community backing, and cultural principles indirectly influence the utilization of herbal remedies through health literacy. The research results can help develop approaches to encourage the correct usage of herbal items, ultimately improving public health.
