Pharmacognosy

Pharmacognosy is the study of medicinal plants.

The term pharmacognosy is used to describe the study of medicinal plants and their active constituents. Pharmacognosists are often herbalists, but this term has been criticized for misleading because it implies that all herbs have a therapeutic effect. The word “pharmacy” means drug or medicine in Greek; thus, pharmacognosy can be defined as the science which studies drugs from natural sources.

Description

Theophrastus first used the term pharmacognosy to describe his studies on plant medicines. In ancient times, many people believed that certain diseases were caused by evil spirits expelled through herbs. These herbs were called pharmacies. Herbalists would use these herbal remedies to treat patients with specific ailments. This practice continued until about 1000 AD, when physicians began using more modern methods such as surgery and anesthesia.

There has been increased interest in herbal medicine in recent years because of concerns regarding side effects associated with pharmaceuticals. Herbal remedies offer several advantages, including lower cost, fewer adverse reactions, greater availability, and more flexibility than pharmaceutical alternatives. However, the use of herbal products also raises questions regarding safety and quality control issues. For example, while most people believe that herbal supplements are safe, there are still risks involved when using them.

There are several reasons why research into herbal therapies remains controversial.

Courses are designed to introduce students to the basic concepts and principles underlying pharmacology, including drug action mechanisms. The emphasis will be on understanding how drugs work in humans by studying their effects on specific organs or systems. Students will learn about the structure-activity relationships for a variety of therapeutic agents and toxicological properties of these compounds.
