Stained Teeth of the Mangyan people

In preparing betel nut for chewing, upland people mix it with apog, or lime powder, before wrapping in a litlit leaf. While chewing, heat spreads throughout the body, keeping it momentarily warm in the upland chill. The apog gives the betel juice its red coloring when chewed and after years of use results in teeth stained red/black.
