OSHA root (Ligusticum porteri) 10:1 extract 150 mg — traditional Southwestern respiratory-support herb. Ethnobotanical use is real but modern RCT evidence base is thin. NusaPure is a budget mass-market brand with 'lab tested' claims but no visible third-party COA linked. 10:1 extract concentration is a positive; vegan/non-GMO baseline. Held below Verified by (1) OSHA root has minimal peer-reviewed RCT support for stated use cases; (2) sustainability concern — wild-harvested OSHA is on some conservation-concern lists; (3) NusaPure quality track record is mixed across their product line. Would move to Verified 70+ with third-party COA + published RCT + sustainable-sourcing certification.
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.

Strongest: Formulation at 55/100 (dose adequacy, bioavailability form, and ingredient redundancy) and Manufacturing at 55/100 (third-party testing, GMP compliance, and facility audit status). Weakest: Evidence at 45/100 (quality of published RCT support for the active ingredients at the label dose) and Sustainability at 45/100 (sourcing practices, packaging, and corporate practice). 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 Verified 70+ with third-party COA + published RCT + sustainable-sourcing certification.
