There is a persimmon tree, big and small, in the yard of Zhouguantun Hydrological Station. Around August 15, persimmons are ripe. At this time, all the persimmons on the tree changed from green to red, forming a beautiful scenery at the station. When the persimmon is ripe, all the leaves of the persimmon tree are gone, leaving only the orange-red round persimmon. From a distance, it looks like a tree full of lights, shining with golden light in the sun. How cute! Picked and dried, the astringency will slowly fade away, leaving only sweet juice. I ran under the persimmon tree with a little curiosity, and I couldn't help feeling a lot when I looked at this strange tree carefully.
Persimmon trees have strong vitality and can adapt to all kinds of growing environments, whether it is fertile fields or barren slopes, hills, fields, ponds or even cliffs. It is really "determined that the green hills will not relax, take root in the rocks, temper their tenacity, and let the east, west, south and north wind blow."
Persimmons are not only delicious, but also nutritious and have medicinal value. Traditional Chinese medicine believes that persimmon is sweet, astringent and cold, and has the functions of clearing away heat and dampness, moistening lung and resolving phlegm, softening hardness and quenching thirst, invigorating spleen and stopping dysentery, and stopping bleeding, and can relieve constipation, hemorrhoid pain or bleeding, dry cough, sore throat and hypertension. Therefore, persimmon is a natural health food for patients with chronic bronchitis, hypertension, arteriosclerosis and internal and external hemorrhoids.
You can't eat persimmons on an empty stomach because persimmons contain more tannic acid and pectin. On an empty stomach, they will form lumps of different sizes under the action of gastric acid. If these masses can't reach the small intestine through pylorus, they will stay in the stomach and form gastric persimmon stones. The persimmon stone with a small belly looks like almonds at first, but it will accumulate more and more. If the stomach persimmon stone cannot be discharged naturally, it will cause digestive tract obstruction, severe pain in the upper abdomen, vomiting and even hematemesis.
If persimmon leaves are decocted or boiled into tea, it can promote metabolism, lower blood pressure, increase coronary blood flow, relieve cough and resolve phlegm. It can resist scurvy, prevent bronchitis and prevent cancer. At present, persimmon leaf tea and other functional foods and drugs for preventing and treating arteriosclerosis, hypertension and coronary heart disease have been developed. If you make tea with persimmon leaf soup or boiled water, it can also promote metabolism, lower blood pressure, increase coronary blood flow, relieve cough and resolve phlegm. Persimmon leaves contain high content of tannin, which affects the taste. It needs seasoning. If mixed well, it can be made into delicious functional food and become a good health food for human beings to prevent and treat "civilized diseases".
When autumn frost comes, persimmon tree still stands tall and straight in front of the station, shedding its beautiful coat and guarding the station like a hydrologist guarding the river bank. When spring is in full bloom, it will continue to strive for upward growth, and it will be fruitful every year, giving people rare sweetness.
