Adaptogen and Other Plant Based Medicinals
Adaptogens are natural plant materials with a variety of pharmacologic compounds that can enhance the human body’s innate ability to adapt to changing circumstances.
Adaptogens are natural substances that help the body adapt to stress and exert a normalizing effect upon bodily processes. In psychiatry, several adaptogens are frequently used for their potential to enhance cognitive function, alleviate anxiety, and support overall mental well-being. Here are some commonly used adaptogens along with their descriptions and relevant research citations:

While Kava, St. John’s Wort, and Valerian Root are not classified as adaptogens, they offer significant benefits for mental health through their anxiolytic, antidepressant, and sedative properties. Adaptogens, by definition, help the body adapt to stress and exert a normalizing effect on bodily processes, which is distinct from the specific therapeutic actions of these three herbs.
