The effect of Toki‐Shakuyaku‐San (TJ‐23) was examined on various models of brain damage in vitro. TJ‐23 (10 mg/mL) significantly protected striatal slices from dysfunction induced by high K + and BAY K‐8644 but not from that by L ‐glutamate and N ‐methyl‐ D ‐aspartate, an effect which was similar to that of nifedipine, a Ca 2+ antagonist. The present findings, therefore, raised the possibility that TJ‐23 expressed a neuroprotective action on hypoxia/ischaemia‐induced brain damage by inhibiting an excess Ca 2+ entry through voltage‐gated Ca 2+ channels.
