龙树:龙血树

 龙树:龙血树

Charles Cook

它的名字来自希腊语 "drakaiano",意思是龙,因为据说它的红色汁液是龙的血液。 古希腊人、罗马人和阿拉伯人已经知道它的药用价值,并将其用于魔法和炼金术仪式。

在中世纪,这种植物被广泛交易,并被用于各种用途,不仅是药用和魔法,而且还用于绘画和清漆。 多年来,关于其来源的秘密被保留下来,导致人们相信它真的是龙血,从而更好地享受其好处和治疗。 在希罗尼穆斯-波什的著名绘画《欢乐花园》中,那棵在左侧面板上发现的是一棵龙树。

栖息地

在它的原产地加那利群岛,它今天仍然被认为是一棵神圣的树,因为它是异教徒的宗教集会所选择的地方。 在特内里费岛,在一个叫Icod de los Vinos的地方,可能有世界上最古老的龙树,尽管很难确定其年龄。

在亚速尔群岛,它被认为是濒危和受保护的物种,也有非常古老的龙树。 它们作为公共和私人花园的观赏树,非常值得赞赏。 由于农业和城市的原因,它们的栖息地已经被破坏。

在皮科岛,在马达莱纳的葡萄酒博物馆里,甚至有一片百年龙树林。 它的自然栖息地是马卡罗尼西亚,但在摩洛哥和佛得角的沿海地区也能找到它,特别是在圣尼科劳岛,是这个岛屿最具特色的树木之一。

在葡萄牙大陆也有一些:里斯本大学植物园有两棵,阿茹达植物园有两棵,其中一棵的年龄不详,但据认为在1768年该园建成之前就已经存在,这棵龙树也是该园标志中的代表树。

在澳大利亚的墨尔本也有商业种植园,它在那里很适应气候。

植物学描述

它有一个粗糙、粗壮的树干,由纤维材料制成,单叶,革质,灰绿色,基部带红色,长而无毛的二回羽状花序,芳香的白绿色花朵,由六片在基部结合而成。 果实是一个球状浆果,大小为14-17毫米,成熟时为橙色。

树液暴露在空气中会形成一种血红色的半透明树脂,形成一种糊状物质,在欧洲被当作龙血高价出售。 它以sanguis draconis的名字用于药理学,是加那利群岛的重要出口产品。

药用用途

虽然今天作为药用植物使用的不多,但龙树在古代被认为是治疗所有疾病的灵丹妙药,从呼吸系统问题到胃肠问题、腹泻、口腔、胃和肠道的溃疡、痢疾、血液凝固剂,对内部和外部伤口、月经疼痛都很有用,也可作为卡他林剂或治疗。它还被用来制作清漆,特别是小提琴的清漆,以及绘画的颜料,一些洞穴壁画甚至被认为是用龙树汁液绘制的。 它被认为是古希腊绘画中最早使用的红色,正是为了代表血液。
