Environmental conditions such as habitat type, vegetation, air temperature, soil temperature, soil pH, and elevation were also gathered. Purposive sampling was done, together with the collection of specimens for herbarium preparation, and gathering data on the environmental factors. Interviews with respondents were done to know the local names and economic uses of each specimen. Sixty-seven (67) species of medicinal plants were found to be present and collected in the study area. In Barangay Don Sixto Balanquit, Sr., all 67 representative species were collected, while 48 species were collected in Barangay Inanahawan, 26 species in Barangay Igot, 59 species in Barangay Cagbigajo, and 32 representative species were collected in Barangay Senonogan. These results imply that there is a diversity of plant species utilized for folk medicine in the study area. Economically, plants in the study area were utilized mainly for human consumption as food, furniture, building and construction, livestock feed, forage, and for medicinal purposes.
