Whether the production takes place inside or outside the body it is a matter of either putting together, separating and/or transforming matter. Seen in a broader perspective creativity is all the methods in which human beings change matter to achieve power over it and often over each other. But it is rarely a matter of creating something new. It is rather a question of refurnishing matter.
The ultimate way of using creativity for ones interests of power is perhaps poisoning: Someone's power over matter leads to someone else's loss of control. There are poisons which only work together with other substances. This is called synergism.
