[译文]药物的来源人类最初所认识的药物是从自然来源获得的;它们或来自诸如罂粟(鸦片)和毛地黄(洋地黄)一类植物,或者就是诸如泻盐和砷一类的简单无机物质。此后,由于有机化学的发展导致合成药物的引用,而目前约有100,000种化合物已进行过药理活性的试验。生物化学和生理学知识的进展,对于药理学已具有特别重要的意义,因为它使生物过程导入了化学控制的概念。维生素类和内分泌激素类早已用作内服药剂 Sources of medicine The drugs that humans first learned were obtained from natural sources; they came from plants such as poppy (opium) and digitalis (digitalis), or simply inorganic substances such as Epsom salt and arsenic. substance. Since then, the development of organic chemistry has led to the introduction of synthetic drugs, and currently about 100,000 compounds have been tested for pharmacological activity. Advances in the knowledge of biochemistry and physiology have been of particular importance for pharmacology because it has introduced biological processes into the concept of chemical control. Vitamins and endocrine hormones have long been used as internal medicine
