Traditional Chinese medicine(...Stroke is the leading cause of human disability with limited effective drugs availability. The disruption of multiple signaling pathways in stroke makes developing new drugs be difficult. Traditional Chinese medicine(TCM) has its unique advantage in targeting multiple signaling pathways with multiple components. Many TCM formulas have the potential for neuroprotection and neurogenesis, but well-designed clinical trials are insufficient and underlying mechanisms unclear. Herein, we introduce the commonly used TCM formulas for stroke treatment and selectively introduce two classic formulas, An Gong Niu Huang(AGNH) pill and Bu Yang Huan Wu Decoction(BYHWD) for neuroprotection and neurogenesis, respectively. Current scientific evidence and clinical trials indicate AGNH pill could be an effective neuroprotective formula as adjunct therapy with relative safety. On the other hand, as a representative TCM formula for post stroke disability, BYHWD could improve the neurological outcome with its neuroprotective and neurogenic effects. The underlying mechanisms could be attributed to the modulation of multiple molecular targets with its multiple components. In conclusion, TCM formulas could be potential adjunct therapies for stroke treatment. The clinical efficacies and molecular mechanisms of promoting neuroprotection and neurogenesis remain to be further studies.展开更多
