One study found that jatamansi, a herb used as a calmative, only partly improves hand steadiness in a seated test and does not raise the score more than training alone · What changed https://matteocampagna.com/en/registry/health/jatamansi-hand-tremor-score Changes to this claim in Matteo Campagna's evidence registry: its status, its year-by-year history, revisions of the page. en-gb Claim page revised, version 2https://matteocampagna.com/en/registry/health/jatamansi-hand-tremor-scoreThere is a single study, and it sets jatamansi against ordinary training. In India, 45 national-level archers aged 16 to 28 were randomly split into three groups for four weeks: one took jatamansi, a root from Indian traditional medicine that the authors describe as sedative; one worked with elastic bands for the shoulders and arms, together with respiratory muscle exercises; the third carried on with usual training, which the other two groups kept up as well. In the steadiness test, seated, holding a probe inside a 4 mm hole for 60 seconds, those taking the root touched the edges for less time than the controls (t = 3.97 with the left arm and 2.69 with the right), but not less often; on the shooting test, 12 arrows at 10 and 20 yards, their group did not differ from the controls, while the band group beat both. The result carries little weight, for four reasons: the paper reports no means or standard deviations, so there is no telling how much the measures changed; there was no placebo and those taking the root knew it; the steadiness test is done without a bow in hand and the shooting test was designed for students; the venue is a regional pharmacology journal. Anxiety, which the authors put forward as the root's route of action, was not measured, and neither was the safety of the preparation.claim:jatamansi-tremore-punteggio:revision:2026-03-20:2Fri, 20 Mar 2026 08:00:00 GMT "One study found that jatamansi, a herb used as a calmative, only partly improves hand steadiness in a seated test and does not raise the score more than training alone" added to the registry as Reportedhttps://matteocampagna.com/en/registry/health/jatamansi-hand-tremor-scoreclaim:jatamansi-tremore-punteggio:new_claim:2026-01-19:riportatoMon, 19 Jan 2026 08:00:00 GMT
