This T'boli woman demonstrates how she chews a certain bark (instead of a betel nut), ikmo, and other herbal plants. What's interesting about it is that she is chewing tree barks. The tree bark has a flavor and the juice in the bark releases the red pigmenu in the saliva. According to those who have tried it, it's refreshing!
