Adaptogens

Adaptogens like ashwagandha, rhodiola, and reishi carry centuries of traditional use in Ayurvedic and Chinese medicine, but rigorous modern clinical trials are a more recent and uneven addition. A few now have a meaningful body of human trials behind specific claims like stress and cortisol; others still rely mainly on smaller trials, animal studies, or traditional-use records. Long history of use is evidence of tolerability, not proof of efficacy for a specific modern claim.
