Based on the phase and composition analysis of 56 batches of samples, the present paper showed that hydrozincite, just as smithsonite, should be named as the mineralogical origin of medicinal galamina. Galamina was proved to be polymineral aggregation by electron probe micro-analysis, which was constituted by various mineral particulates, such as hydrozincite, smithsonite, zinc oxide, dolomite, etc. It is hydrozincite but not smithsonite that is the current mainstream mineral of commercial galamina. Both hydrozincite and smithsonite should be calcined to turn into zinc oxide when they were used as medicine. As a provider of medical galamina, essentially the zinc oxide, hydrozincite is appropriate.%通过对56批炉甘石样品的物相与成分分析,为增补水锌矿作为炉甘石基源矿物提供了依据.电子探针微区分析表明:炉甘石是一种复杂的矿物集合体,由水锌矿、菱锌矿、异极矿、白云石、方解石等多种散在共生的微小矿物颗粒共同构成；红外光谱结构分析的结果显示:市售炉甘石的主流矿物为水锌矿.炉甘石药用均为煅烧后入药,作为炉甘石基源的水锌矿与菱锌矿,经炮制后其化学成分均转变为氧化锌,两者化学本质相同.故在保证原矿品质的前提下,两者可共同作为炉甘石的基源矿物.
