The data collected in this study were analysed and graphed by using Microsoft Office Excel (2010) and RStudio software (4.1.1), including the informant consensus factor (ICF) and use frequency (UF). A quantitative data analysis was conducted using the ICF method and the number of citations. The ICF was calculated as the ICF = (Nur − Nt)/(Nur − 1), where Nur is the sum of plant species used by all the respondents to treat a particular disease and Nt is the number of identical plant species used by all the respondents to treat a particular disease [24 ]. The use frequency of medicine sold on the market was estimated with the utilization frequency [25 (link)]. The UF is calculated as UF = Nm/Ni, where Nm is the number of use reports of medicinal materials mentioned by informants, and Ni is the total number of informants. High UF values indicate that the herb is used more frequently in the region.
