Traditional Caribbean 'Ram Goat Dash Along' is often botanically Turnera diffusa (damiana) or the closely related Turnera ulmifolia; both have long ethnobotanical use as aphrodisiacs and mild anxiolytics. The modern human evidence is thin — one small combination trial (ArginMax; Ito 2001/2006) that used damiana alongside arginine, ginseng and vitamins, plus preclinical MAO-A inhibition data — none of which isolates damiana at a specific studied dose. Sold as loose raw herb with no standardization, no per-serving mg, and no third-party COA. Species identity ambiguity between Turnera diffusa and T. ulmifolia is a specific concern given the same common name is applied to both in Jamaica. Would move to Standard 55+ with confirmed species, a defined dose range matched to traditional use, and third-party identity testing.
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

Would move to Standard 55+ with confirmed species, a defined dose range matched to traditional use, and third-party identity testing.
Strongest: Safety at 55/100 (adverse-event profile, interaction risk, and dose ceiling) and Sustainability at 55/100 (sourcing practices, packaging, and corporate practice). Weakest: Manufacturing at 45/100 (third-party testing, GMP compliance, and facility audit status) and Evidence at 42/100 (quality of published RCT support for the active ingredients at the label dose). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.
Would move to Standard 55+ with confirmed species, a defined dose range matched to traditional use, and third-party identity testing.
