Opopanax, also known as opobalsam, refers to a number of gum resins (natural substances that are a mixture of water-soluble gums and alcohol-soluble resins) traditionally considered to have medicinal properties. Pliny (''Historia Naturalis'') and Dioscorides (''De Materia Medica'') described various kinds with uncertain identifications, which have been distinguished as: * A species of ''Centaurea'' * Lovage (''Levisticum officinale'') * Yarrow (''Achillea millefolium'') * ''Echinophora tenuifolia'' (Umbelliferae) * ''Ferula opopanax'', also known as ''Opopanax chironium'' (Umbelliferae) * Fig-leaved cow parsnip, ''Heracleum panaces'' (or other species of ''Heracleum'') In recent times, the main source of commercial opopanax is from species of ''Commiphora'', particularly ''C. erythraea'' and ''C. kataf''.〔 (Some sources suggest the entire production is from ''C. erythraea'' var. ''glabrescens'', a tree growing in Somalia.) Myrrh is also obtained from ''Commiphora'' species.〔 == Etymology == The name opopanax derives from Anglo-Norman ''opopanac'', from Latin opopanax, from Hellenistic Greek ὀποπάναξ, from Ancient Greek ὀπός "vegetable juice" + πάναξ "panacea" (all healing).〔(【引用サイトリンク】work=Oxford English Dictionary ) (subscription required)〕 Panacea (Gk. πανάκεια) denotes a kind of savory, named for Panakeia, a daughter of Aesculapius. The OED gives ''opopanax'' as the principal spelling, but lists ''opoponax'' as a variant spelling recorded from the 19th century. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Opopanax」の詳細全文を読む スポンサード リンク
