What be that thing offered, or a gift, in the presence of someone face to face, in the situation in question. And of being there, on the notion of bringing something into someones presence and meaning to this point in time, to share with someone and not to be a medicine given, merely in a belief to please (placebo) than to really benefit the patient?
Natural is a thing that is particularly suited for something.
A male is natural for a female.
The vegetables are natural food for the living animals.
Some animals are natural prey for other animals.
An insect or some other small creature is therefore used as bait, rather than an artificial imitation of a spiritual or a supernatural.
Because the artificial spiritual and supernatural just do not fit into the naturals.
