Pear fruit: it has the effect of generating jin, moisturizing, clearing heat, phlegm, etc., and is suitable for fever and thirst, alcohol, hot cough, phlegm fever, choking, thirst loss, red eyes, swelling and pain, and indigestion.
Pear peel: has the effect of clearing the heart, moisturizing the lungs, reducing fire, generating jin, nourishing the kidneys, and tonifying the yin.
Pear seeds: Pear seeds contain lignin, an insoluble fiber that dissolves in the intestines to form a gum-like film that binds to cholesterol in the intestines to eliminate them.

1. Pear flavor sweet and cold, clean heart and lungs. It is effective for patients with tuberculosis, tracheitis and upper respiratory tract infections such as dry throat, itching, hoarseness, and thick sputum. In the autumn when the climate is dry, eating one or two pears a day can alleviate the autumn dryness and benefit the health.
2. Pears have more sugars and vitamins, and the pectin content is also very high, which can promote appetite and have a protective effect on the liver.
3. Pears are rich in fiber, which can help people prevent constipation and digestive diseases, purify the kidneys and clean the intestines.

4. Pear can prevent atherosclerosis, inhibit the formation of carcinogen nitrosamines, protect the heart, and enhance myocardial vitality.
5. Cooked pears help the kidneys excrete uric acid and can prevent gout, rheumatism and arthritis.

China is one of the important origins of pear plants in the world, and is the world's largest pear and fruit growing country and a big pear producing country. At present, the total area of pear cultivation in China is about 1.1127 million hectares, and the total output is about 18.7049 million tons, accounting for 68.71% of the total area of pears in the world and 68.42% of the total output, which is the third largest fruit in China after apples and citrus. Pear is an important fruit tree cultivated worldwide, and has been cultivated in China for more than 3,000 years. There are two broad categories of cultivated pears in the world:
China, Japan, South Korea and other Asian countries are dominated by oriental pears, the fruit is mainly round, a few are oval; its flesh is crunchy and juicy, the taste is sweet and crisp, and it can be eaten after the tree is ripe. The current cultivated species mainly include white pear, sand pear, autumn pear, Xinjiang pear and Western pear.
Asian pear (red crispy)
Western countries such as Europe and the United States are dominated by Western pears, and the fruits are mainly gourd-shaped, and after harvesting, they usually need to go through a period of "post-ripening" (similar to kiwifruit) to eat, and the taste is soft, sour and sweet, with a rich aromatic flavor.

Since the end of the 1970s, the "Pear Germplasm Improvement" team of the Zhengzhou Institute of Pomology of the Chinese Academy of Agricultural Sciences has been aiming at the favor of the international fruit market for red-skinned pears and innovating new varieties of red-skinned pears. After the unremitting efforts of 3 generations of scientists, on the basis of cultivating 2 generations of red-skinned pear "red crisp", using the distant hybrid multi-gene polymerization technology, the new varieties of 3 generations of red-skinned pears that have inherited the advantages of the 2nd generation of red-skinned pears and overcome their shortcomings have been cultivated, such as red crisp honey, Danxia red, red crisp treasure, early red jade, red agate, early red honey, etc.
