Read the deep dive →Herbs used for stress, stamina and cognition. “Adaptogen” is a category from Soviet-era research rather than a regulatory term, so each page states what was actually measured, in whom, and at what dose.
A herb is filed here by what it is traditionally used for, not by a claim that it works. Each herb page states its own evidence tier, its documented harms and its drug interactions — read those before the category name.
