Evidence Anchor

BioHarmony 6/10

Kava is a 6.0 / 10 Neutral: a real, fast-acting, non-addictive anxiolytic with a strong short-term and traditional evidence base, pulled down to the middle by one specific intrinsic safety problem rather than by weak efficacy. It is worth considering for adults with situational or short-term generalized anxiety who want benzodiazepine-like relief without the addiction risk, and who will respect the sourcing rules. It should be avoided by anyone with liver concerns or alcohol use. The Neutral tier is justified because the effective-but-risky balance genuinely sits at the center, not because the plant does not work. ✅ Best for: Adults with situational anxiety (public speaking, flights, stressful events) who want fast relief without a daily prescription. People with short-term generalized anxiety seeking a non-addictive alternative to benzodiazepines who will keep courses short. Those who specifically want to avoid the dependence, withdrawal, and sexual side effects of conventional anxiolytics, a profile Sarris 2009 supports. Careful consumers who will buy verified noble-cultivar aqueous root products and monitor how they respond. People who tried other calming supplements with no effect and want something with a genuine clinical signal. ❌ Avoid if: You have any liver disease or elevated liver enzymes, since the intrinsic hepatotoxicity risk is the whole story here. You drink alcohol regularly or take acetaminophen, because the combination compounds liver stress. You are pregnant or breastfeeding. You take medications metabolized by cytochrome P450 enzymes, which kava inhibits, raising interaction risk. You are looking for a long-term anxiety solution, given the null 16-week Sarris 2020 result. Sourcing caveat: never buy unlabeled concentrates, acetone or ethanol extracts, aerial-part products, or non-noble tudei kava, which is where most liver-injury reports originate.

My score and my verdict: one signal of three, never the whole answer.

Momentum

Signals begin with Edition 2

Direction needs two weekly snapshots to compare, so the arrows stay off until the next edition. Attention tracking is already running.

Momentum = how fast attention is rising across search, Reddit, PubMed, podcasts, and curated industry newsletters this week; it can flag an item as Overhyped/Fading, but it never overrides the evidence behind Proven. How momentum works.
