It also aimed to find out if this group continued their ancestors” practice of using the areas” plants with curative effect or medicinal value in the light of advances in the field of medicine. Findings suggest that, like other Philippine indigenous groups, this group of Mandaya’s has been affected by its contact with lowlanders. The depletion in the quantity of the products regularly churned out by the forests, the seas, and the rivers due to man’s exploitation of the earth’s natural resources has changed them from being self-reliant to dependent consumers of the goods produced by the market economy.

Plants identified as having curative or medicinal value are still widely used by the members of the group
