#conkers#differences between conkers and chestnuts 栗子和七叶树之间的区别 当谈到七叶树和栗子时，许多人会感到困惑。它们看上去相似，七叶树果实通常被称为七叶树，这使很多人感到困惑。我们需要了解的一件事是，栗子很甜，可以食用，但是七叶树或七叶树是有毒的，它们不是为了食用。七叶树看起来很可食，但有毒，甚至可能导致麻痹。两者都有相似的特征，人们经常误以为七叶树是栗子。 七叶树最具活性的成分，七叶树叶子有独特锯齿掌状，种子是暗褐色的硬壳状，与栗子外型相似，几世纪以来在欧洲医学已经开始广泛使用，磨碎加入茶中饮用可以加强新陈代谢帮助心血管功能，或涂抹关节治疗风湿与关节炎。 医药用途 编辑 欧洲七叶树的种子含有大量的皂素，叫做七叶素（Aescin），外用可以强化静脉及促进下肢静脉循环的功能，口服则有毒性，但此成分不耐高温，蒸煮后种子中的淀粉可被食用。近几年研究发现七叶素（Aescin），有抗炎、血管收缩和血管保护作用，助于术后或运动伤害引起的浮肿，也常被用来治疗静脉曲张。简单来说，七叶素具有舒缓、消炎、镇静的效果，可提高肌肤的防护能力，减少敏感肌的发生，也常被使用在外用药品及化妆品中，为欧洲畅销的草本植物。七叶树不仅可作为观赏植物，其树皮、果实、种子都可用在不同的医疗用途，可以用于保护血管，抑制发炎和清除自由基性质。传统上以其叶子治疗咳嗽、发烧与减少关节炎及风湿引起的疼痛。其种子捣成糊状，敷于皮肤可治皮肤病变，内服及外用皆可治疗静脉曲瘤与痔疮，也有助于术后或运动伤害引起的浮肿，还被用来治疗静脉曲张。 现今最为人所知的效用在于血管方面，七叶素会使血管收缩，可治疗静脉曲张和下肢慢性静脉功能不全症(疲倦、疼痛、腿部肿胀等)、静脉炎、水肿、痔疮、溃疡、冻疮、瘀血、打伤、撞伤、挫伤、拉伤、扭伤、瘀伤和局部浮肿等有助益。 以下是栗子和七叶树之间的一些区别： 习惯： 七叶树通常大，它们的高度超过100英尺。这棵树是圆顶形的，在春天时，它的白花在其基部有红点。栗树只长到40英尺，也有白花，但在六月开花。板栗树的花朵散发出浓烈的香气。 树叶： 两棵树都是落叶的。栗树的叶子呈黄绿色，有光泽，在秋天时变成完全黄色。七叶树的叶子是绿色的，但是与甜栗树相比，它们更粗糙，更大。七叶树的叶子成熟时颜色变深。 坚果： 栗树的坚果很甜，有两到三个泪珠状的种子。这些坚果是棕色的，也可以食用。另一方的七叶树果实不可食用，因为它们含有一种叫做七叶皂苷的有毒化学物质，会引起呕吐和麻痹。七叶树果实苦涩，人们经常将七叶树果实与栗子混为一谈，因为这两种坚果看上去都很相似。 文化： 七叶树需要排水良好的土壤。只要排水良好，它就可以在任何土壤上繁衍生息。栗树需要潮湿且排水良好的土壤。两棵树都需要大量的阳光和土壤中的水分。 栖息地： 七叶树在欧洲东南部很流行，它生长在混交林中。栗子来自美利坚合众国，在东部的硬木森林中发现。 知识： 随身携带七叶树以带来好运和魅力。英国的学童将它们绑在鞋带上，并用力砸在地板上与它们一起玩耍。 人们常常混淆这两种种子，因为它们看起来非常相似。丰富的棕色使两种种子都具有吸引力。有些人可能会觉得自己可以烤和吃，但是决不能以任何形式食用七叶树。它甚至不能仅仅因为被称为马七叶树而喂给马。当给猪喂七叶树时，他们拒绝吃猪，但是像鹿和野猪这样的动物吃了这些种子，因为它们的身体能够分解种子中存在的化学物质。 DIFFERENCE BETWEEN CHESTNUTS AND CONKER JANUARY 20, 2018 ANNIE A. COON Many people get confused when it comes to conkers and chestnuts. They both look similar, and conkers is often called as horse chestnuts, and this confuses a lot of people. One thing we need to understand is that chestnuts are sweet and they are edible but conkers or horse chestnuts are poisonous, and they are not for eating purposes. Horse chestnuts may look very desirable to eat but it is toxic, and it can even cause paralysis. Both have a similar feature and people often mistake conkers for chestnuts. The following are some of the differences between a chestnut and a horse chestnut: HABIT: Conkers trees are usually large, and they are more than 100 feet tall. The tree is dome-shaped, and during springtime, the tree has white flowers which have red dots at its base. While the chestnut trees grew only up to 40 feet and they also have white flowers, but it blossoms in June. The flowers of the chestnut tree produce a strong fragrance. LEAVES: Both the trees are deciduous. Chestnut trees have yellowish green leaves which are shiny, and they turn completely yellow during the fall. Conkers leaves are greenish, but they are more coarse and large when compared to that of the sweet chestnut tree. The leaves of the horse chestnut trees become darker in colour when they mature. NUTS: The nuts of the chestnut tree are sweet, and they have two to three teardrop-shaped seeds. These nuts are brown, and they are also edible. Conkers on the other side are not edible as they have a chemical called aescin which is poisonous and it can cause vomiting and paralysis. Conker nuts are bitter and people often confuse conkers with chestnuts as both the nuts looks quite similar. CULTURE: Conkers needs well-drained soil. It thrives on any soil type as long as it is well drained. The chestnut trees need moist and well-drained soil. Both the trees require lots of sunlight and moisture in the soil. HABITAT: Conkers is popular in the South-eastern part of Europe, and it grows in mixed forests. Chestnuts are from the United States of America, and they are found in the Eastern hardwood forests. LORE: Horse chestnuts are carried for good luck and charm. The British schoolchildren tie them to their shoelaces and play with them by smashing it hard on the floor. It is common for people to confuse between both these seeds as they look very similar. The rich brown colour makes both the seeds quite appealing. Some may feel that they could roast it and eat, but conkers must never be consumed in any form. It must not even be fed to horses just because it is named as horse conkers. When conkers were given to pigs, they refused to eat them, but animals like deer and wild boar eat these seeds as their body is capable of breaking down the chemicals that are present in the seeds.
