Chapter 6: Introduction

In this chapter, we explore a variety of medications and supplements to help us understand their impact on physical and mental well-being.  We will review what type of medications are used for psychological disorders, which over-the-counter medicines may be appropriate for health concerns, and which supplements people are using for health and well-being.  In addition, we will examine the drug development process and the phases of clinical trials to learn how medications and supplements are tested and approved for human consumption.
