This research is limited because it looked at past records rather than a controlled trial. It examined 942 people in Korea who had stroke symptoms and used herbal medicines. Most started treatment more than a year after their stroke happened. The program was funded by the Korean government.
Researchers checked health records to see how patients felt over time. About one in five patients improved, while most stayed the same. A small number reported getting worse. The data came from insurance claims, not direct doctor visits. Records covered visits between 2020 and 2024.
Safety information was limited because the study relied on recorded codes. It did not track specific side effects or how many people stopped taking the medicine. This was an observational study, so it cannot prove the medicine caused the changes. Side effects were not counted in the report.
Patients should talk to their doctors before starting new treatments. This research helps understand everyday use but needs more careful testing. It shows a link, not a guaranteed cure for stroke recovery. Doctors can help weigh risks and benefits.
