If it is not already in your items, you may have to reset the island to continue. The bone should be down in the pit next to the statue with the crawly worm.
First, get the key ingredient and the coconut milk (Main Street), get and wear the grass skirt from Booga Bay, and climb the vine to see the medicine man. If he takes the ingredients, then it was just a glitch on the Item Bag. If not, click the small map and "Restart Island."
