Summary
Hypothalamic-Pituitary Agents and Adaptogenic Herbs
introduction:
According to the original definition, adaptogen herbs are characterized by minimal toxicity, have generalized actions, and have normalizing effects whatever the direction of the pathological state. Adaptogens are commonly considered to increase the ability to deal with a wide range of stressors, an action thought to be mediated via the limbic-hypothalamic-pituitary-adrenal axis.
The widely studied adaptogens include Panax ginseng (Chinese/Korean Ginseng) and Eleutherococcus senticosus (Siberian ginseng). Several other herbs have been shown to have anti-stress, anti-fatigue and general neuroendocrinological effects, some of which have been little studied.
