Many substances in the natural environment have been discovered to have great medical value for human beings as medicinal drugs. For example, quinine used to treat malaria comes from the bark of the cinchona tree and penicillin is traced to a fungi. On the one hand, these substances reflect the creativity of God. On another level, these drugs reflect thelove of God, as well as the unity of nature—for why should substances from trees, molds, and other organisms distantly related to human beings be of such medicinal value to human beings? Pain, inflammation, fever and many other ailments can be addressed through such substances from other living organisms.
The identification, production, and synthesizing of drugs also reflects human creativity, derived from God. For example, aspirin came from noticing the effects of the bark of the willow tree and then making improvements to help in its use.
However, many drugs also have been tied to abuse, resulting in physical, social, and psychological harm, and the illegal drug trade has been linked to violent crime and other societal harms. These reflect the lack of mind/body unity within humans, who find themselves seeking artificial means to alter their mental state and being willing to harm their body and mind in the process.
