Scott Alexander evaluates silexan, a lavender-based anxiety supplement, finding promising but potentially biased evidence, and recommends cautious trial use.
Longer summary
Scott Alexander reviews the evidence for silexan, a lavender-derived supplement claimed to be highly effective for anxiety. He examines the studies, noting that most are by one researcher with conflicts of interest, but finds the methodology generally sound. He also considers circumstantial evidence, including animal studies and anecdotal reports. While cautioning about the lack of independent research, Scott concludes that silexan is worth trying due to its low risk and potential benefits, and predicts a 50% chance it will prove as effective as SSRIs for anxiety in future independent studies.
