A Rainbow of Medicine
One medicine might be a pink liquid, another medicine might come in a special mist, another might be a blue pill, and still another might come out of a yellow tube. But they're all used for the same purpose — to make you feel better when you're sick.

Most medicines today are made in laboratories and many are based on substances found in nature. After a medicine is created, it is tested over and over in many different ways. This allows scientists to make sure the medicine is safe for people to take and that it can fight or prevent a specific illness.

Many new medicines actually are new versions of old medicines that have been improved to help people feel better quicker.
