The most commonly cited examples would be ginseng and ashwaganda.
Something of a neologism I believe.
To quote wikipedia:
Adaptogen
From Wikipedia, the free encyclopedia
The word adaptogen, coined by Russian Scientist Dr. Nicolai Lazarev in 1947, refers to a natural herb product that increases the body's resistance to stresses such as trauma, anxiety and bodily fatigue. The guidelines Lazarev created for an herb to be considered an adaptogen are:
It must cause only minimal disorders in the body's physiological functions;
It must increase the body's resistance to adverse influences not by a specific action but by a wide range of physical, chemical, and biochemical factors;
It must have an overall normalizing effect, improving all kinds of conditions and aggravating none.
