- It is Korean individually recognized ingredient 2022-25 with a daily intake of 500 mg.
- Finished joint-health products containing the ingredient are distributed in Korea, but combination products cannot be directly equated with a single-ingredient trial.
- Traditional root preparations or edible greens differ from the standardized leaf extract in plant part, manufacturing, and dose.
- Public human data on long-term use and drug interactions are insufficient, so safety is listed separately as unknown.
What the research actually shows
Korean regulators recognized Angelica decursiva leaf extract under number 2022-25. Manufacturer materials state that a randomized double-blind controlled trial was conducted at Pusan National University Hospital in 2019 and 2020, but do not disclose the sample size, primary endpoint, or complete results, and no searchable peer-reviewed clinical paper was identified.
Why this is classified as C (41)
One manufacturer trial exists, but its sample size, primary endpoint, and results are undisclosed and independent replication is absent, supporting C with 41 points.
