The sickness needed a bone and hair to come out into. A material container for a non material item, a representation of the disease. From the shaman's perspective when they hold the item and say it is the sickness, they are not simply lying, but they are showing a visual manifestation of the disease. I would imagine that a shaman would keep such items on hand.
Very clever way of explaining the phenomenon !
It suits both westerner's rational mind and tribal magical belief.
