丁香是一种重要的常用中药。它是桃金娘科植物丁香的干燥花蕾,有温中降逆,补肾助阳之功效。主产东非和东南亚。1990年版《中国药典》将丁香原植物学名定为Eugenia caryophyllata Thunb.,现经考证研究,此植物学名系一分类学异名。根据《国际植物命名法规》规定,每一种植物只能有一正确的学名,故此异名应以废弃,需采用其正确学名。经考证,早在1753年,Linnaeus在他的《SpeciesPlantarum》一书中已将丁香学名定为Caryophyll-us aromaticus L.。但后来分类学家认为Linnaeus创立的Caryophyllus属实际上包括了他自己建立的番樱桃属Eugenia和部分Jambosa属,故此学名应以废弃。1788年Thunberg将丁香归人番樱桃属,并定名为Eugenia caryophyllata Thunb.。此后由不同的植物学家命名的丁香学名不断增多,约达10余种,如Eugenia aromatica(L.)Baill.,Myrtus caryo-phyllus Spreng.,Jambosa caryophyllus(Spreng.)Niedz.,Eugenia caryophyllata Willd.,Eugenia ca-ryophyllus(Spreng.)Bullock et Harrison等。 Cloves are an important commonly used Chinese medicine. It is a dry bud of myrtle plant clove. It has the effect of lowering temperature in the middle of the body and helping the kidney. The main production is East Africa and Southeast Asia. In the 1990 edition of the Chinese Pharmacopoeia, the original botanical name of the clove was Eugenia caryophyllata Thunb. Now it is researched and researched. This botanical name is a synonym of taxonomy. According to the “International Plant Nomenclature Regulations”, each plant can only have one correct scientific name. Therefore, the different name should be abandoned and its correct scientific name should be used. According to his research, as early as 1753, Linnaeus named Caryophyll-us aromaticus L in his book “Species Plantarum”. However, taxonomists later believed that the genus Caryophyllus founded by Linnaeus actually included the Eugenia and some Jambosa genuses that he founded. Therefore, the scientific name should be abandoned. In 1788, Thunberg classified Lilac as a member of the genus Prunus and named it Eugenia caryophyllata Thunb. Since then, the name of the clove has been named by various botanists and has grown to about 10 species, such as Eugenia aromatica (L.) Baill., Myrtus caryophyllum Spreng., Jambosa caryophyllus (Spreng.) Niedz., Eugenia caryophyllata Willd. Eugenia ca-ryophyllus (Spreng.) Bullock et Harrison et al.
