中藥與西藥的比拼經常出現,箇中經常出現的論據就是中藥缺乏科學精密驗證,純粹是依靠經驗及神農嘗百草的方式積聚理論。379Please respect copyright.PENANAYqLXE4DlBW

本篇文章無意將中藥及西藥對衡,而是嘗試以西醫科學角度審視一款中醫藥材,三七。379Please respect copyright.PENANAmUbWijFCKF

(圖2)左圖為Panax notoginseng(三七);379Please respect copyright.PENANAKQ6wP8nOqx
379Please respect copyright.PENANA6F4q1VWyAB
中圖為Sedum aizoon(土三七);379Please respect copyright.PENANAlC0OWxCaEH
379Please respect copyright.PENANAiT81NfqaTr
而右圖則為Gynura japonica,頻繁被誤當成土三七的藥材。379Please respect copyright.PENANAwkapfm25Iw

(圖3)不幸的是,這款誤當成土三七的藥材內含名為pyrrolizidine alkaloids (PAs)的化學物;379Please respect copyright.PENANAFcMc5EF9XR
真正的三七及土三七並不含PAs。379Please respect copyright.PENANAJ72frxNsfk

這些PA化學物進入人體後,會形成DHPA及DHP化學物。379Please respect copyright.PENANA4K2sm1a64L
379Please respect copyright.PENANADzYPyivRZN
而DHPA及DHP化學物會與肝臟內各種蛋白質結合,導致肝臟無法運作正常。379Please respect copyright.PENANA1luTagr49I
379Please respect copyright.PENANAubqPaj4n0Y
根據資料統計(Ref1),誤當Gynura japonica作為土三七下藥,構成了中國在2017年約10-30%因攝取藥物導致肝臟收損的個案。379Please respect copyright.PENANAli8qSWyPOm

這亦表示,若有經驗不足的中藥醫師或商人胡亂購買藥材的話,將會無意之間害了別人。379Please respect copyright.PENANAqAmRMycncr

能否有系統分配及管理中藥藥材的類別,將會是現今中醫所需面對的問題。379Please respect copyright.PENANABpqCDHW9Hb
