Lots of adaptogens. Best way to research this is pick up any herb
book that covers herbs from all over the world; it'll have a section on adaptogens. Planetary Herbology is a good one, and any book on Chinese medicine will cover this. Ashwagandha, of course, is from ayurvedic, or traditional Indian medicine, and they would necessarily use the term adaptogen, but with herbs having gone global, all systems have been incorporated by herbalists.
