Weng SW, et al. - Researchers analyzed eligible stroke cases who did (n=8971) and did not (n=8971) receive Bu Yang Huan Wu Tang (BYHWT) to compare the long-term risk of epilepsy in both the cases by using Cox proportional hazard models. They observed a declination of the long-term risk of epilepsy in stroke patients who received BYHWT therapy during the 5–9 years of the follow-up period. A dose-dependent reduction in the frequency of epilepsy with increasing quantities of BYHWT use from 1 package to ≥6 packages was also recorded.
