The study was aimed to determining the knowledge, patterns of use, and attitude towards the use of complementary and alternative medicines (CAM) by herbalists (n=38) and lay people (n=582) from the municipalities of Indang, Maragondon, Amadeo, Magallanes, and Alfonso and the city of Tagaytay, all located in the upland portion of the province of Cavite. Data pertinent to the afore-said aims were gathered through questionnaires and focus group discussions. Nine forms of CAM were documented as used by the interviewees. Leaf extract (decoction) and traditional massage (hilot)was the most prevalent types of CAM across all studied areas, contributing 71% (n= 440) and 54% (n= 335), respectively. Furthermore, their widespread utilization was mainly due to the recommendations from family members (31%, n=192) and doctors (35%, n= 217). Amongst the various ailments associated with the use of CAM, common colds (70%, n= 434), cough (69%, n=428), and fever (61%, n= 378) were the most treated. Overall, a generally positive attitude towards the use of all forms of CAM recorded in this study was shown by most participants in all the surveyed municipalities/city. Therefore, present study concludes that CAM plays a major health care role amongst the interviewees.
