Moderate (anxiety, sleep)
A climbing vine with intricate purple-and-white flowers, native to the southeastern United States and used by both Indigenous peoples and 19th-century American herbalists. Modern research backs its traditional use for anxiety and sleep — gentle in effect, with effects on the same calming pathways targeted by prescription anti-anxiety medications.
