With the development of the world and the advancement of science and technology, we can use the Network to learn about the customs and specialties of various countries without leaving home, and we can see the flowers and flowers of this world at home. Some time ago, some netizens posted photos of their trip to Italy on Weibo, and even caught fire in the circle of identification. Just looking at the photos, I also feel envious, this is really full of "chestnuts" ah! It looks full, and many netizens lament that they have found a way to get rich. However, a skilled friend said the natural opportunity: this is poisonous, eat poison to turn you over! It also stopped the boom in buying airline tickets.
The "chestnuts" on the ground look very similar to the chestnuts we usually eat, but they are not. Its scientific name is horse chestnut, which is the fruit of the European horse chestnut tree: horse chestnut seeds. Horse chestnut looks very much like sweet chestnut, so people will mistakenly think that it is a chestnut we often eat, but it is very different from sweet chestnut taste, and the taste is bitter, so the taste of horse chestnut is not good, so in Italy it can only be used as horse feed!
Although the horse chestnut itself is toxic and we cannot eat it directly, its extract has high medicinal value, horse chestnut extract contains horse chestnut contains horse chestnut to help blood vessel constriction effect, which can be used to activate blood stasis, can also treat muscle strains, and even as a hemorrhoid medication.
So how do we distinguish between horse chestnut and chestnut to prevent accidental eating? We can distinguish by appearance:
The surface of the chestnut has obvious pinstripes arranged in a regular manner, while the horse chestnut has a smooth surface and no particularly regular lines.
The shape is different: the chestnut is hemispherical and flattened on one side, while the chestnut appears very rounded and rolling.
Third, there is a difference in size: horse chestnuts are generally larger, while chestnuts are large and small.
The toxicity of horse chestnut comes from a substance called saponin, also known as horse chestnut. It will destroy the body's red blood cells, when the human body takes the dose more than the body's immune function, it will stimulate the intestine, damage the central nervous system function, and die. Although we can't eat it, horses, squirrels, and deer are exceptions. That is to say, God opens a window for you, and you have to close a door for you!
