Traditionally drugs were extracted from plants and moicroorganisms:
- Digitalis is a heart drug that originates with foxgloves
- Aspirin is a pain killer that originates from willow
- Penicillan waxs dicovered by Alexander Fleming from the Penicillium mould
Now the most new drugs are synthesised (made) by chemists in the pharmaceutical industry. However, the starting point may still be a chemical extracted from a plant.
