Sinukuan (sinuku/suko means surrender) is believed to be a mystique tree from the highlands. Having a piece of the wood (Sinukuan) will protect its bearer from evil spirits and illnesses caused by them and any other creatures. It is said that the tree of Sinukuan can be found on a secluded mountain in Bicol region and in some forest in Mindanao. It is very risky to go near the tree specially during daylight or on moonlit nights as it will paralyze whoever goes under its shadows. It is also said that with the Sinukuan, the possessor will not have (or less) trouble with people, making them give in or agree to his liking.
