Passionflower for Anxiety Relief

Research suggests that passionflower may offer meaningful relief from anxiety symptoms, with evidence drawn from a 2018 systematic review of 100 randomized controlled trials finding that passionflower performed comparably to standard anti-anxiety medications while producing fewer side effects. A 2022 narrative literature review further identified passionflower as a candidate for managing anxiety and other neurological symptoms, including those associated with post-COVID-19 conditions, based on its known bioactive compounds. Both sources lean in a supportive direction, though it is worth noting that neither represents new experimental findings specifically focused on passionflower — the systematic review pooled evidence across many herbs, and the 2022 publication is a narrative review subject to interpretive bias. Authors across both sources consistently emphasize that larger, more rigorously designed clinical trials are needed before firm conclusions can be drawn about passionflower's effectiveness for anxiety.
