Li Qingyun was born in 1677 and died in 1933, living for 256 years. He is a Chinese medicine scholar in the late Qing Dynasty and the early Republic of China, and also a world-famous long-lived old man. 100 (1777) was awarded a special prize by the government for his outstanding achievements in traditional Chinese medicine. At the age of 200, he still often went to university to give lectures. During this period, he received many visits from western scholars. Li Qingyun married 24 wives in his life, and all his children were plump. He thinks there are three reasons for his health and longevity: first, he has been a vegetarian for a long time; Second, he has always maintained a calm and cheerful heart; Third, he drinks boiled water to make tea all the year round. After hearing the news, medical researchers in Britain and France made an in-depth study of Qi. They found that Lycium barbarum contains a vitamin that they have never seen before, so they named it "Vitamin X". Also known as "skin care vitamins". Animal experiments have proved that Lycium barbarum can inhibit the accumulation of fat in fiber, promote the regeneration of liver cells and reduce blood sugar and cholesterol. Qi Qi's "rejuvenation" can stimulate gonads and endocrine glands, enhance hormone secretion, strengthen the physiological functions of brain cells and nerve cells, and prevent toxins from accumulating in the blood with age, thus maintaining the normal functions of various tissues in the body.

He has been interviewed by many western scholars and attributed his health and longevity to using Lycium barbarum to boil water and make tea all the year round. Because of his strong advocacy, Lycium barbarum is widely used for health care. In fact, the beauty beauty and life-prolonging effects of Lycium barbarum were recorded and discussed in ancient medical books. "Materia Medica Jing Shu" said: "Lycium barbarum, moistening dryness and nourishing, can also clear away heat, but it specializes in tonifying kidney and moistening lung, promoting fluid production and benefiting qi. It is an important medicine for tonifying liver and kidney for deficiency of true yin and fatigue. Seven or eight out of ten elderly people are yin deficiency, and eating at home is good for their eyes. " "Herbal Yan Hui" said: "Lycium barbarum can invigorate qi, enrich blood, nourish yang, nourish yin, reduce pathogenic fire, and remove rheumatism, which is of great use. "Materia Medica Xuan Tong" said: "Lycium barbarum can tonify kidney and replenish essence, strengthen water (kidney) and strengthen bones, while thirst, dizziness, lumbago and knee pain are all cured." Materia Medica says: "Lycium barbarum is heavy and refined, so it can replenish yin, and there is yang in yin, so it can replenish qi." Therefore, nourishing Yin does not lead to yin decline, and helps Yang Can to make Yang prosperous. Its merits make eyes and ears clear, replenish essence and marrow, strengthen bones and muscles, and repair injuries; Especially those who have thirst quenching, true yin deficiency and persistent umbilical abdominal pain should use miraculous effects. Therefore, Chinese medicine practitioners and health experts in past dynasties have attached great importance to the health care function of Lycium barbarum. Ge Hong of the Eastern Jin Dynasty (284-364 AD), Tao Hongjing of Qi Liang of the Southern Dynasty (456-536 AD), Sun Simiao of the Tang Dynasty (58 1-682 AD) and other well-known birthday stars lived to be 80 years old. They all like to drink chinese wolfberry wine. There is also a folk custom in China to take Lycium barbarum for health preservation, calling Lycium barbarum "the sparrow's father", which means to stay in the face and guard against old age. According to Taiping Sheng Huifang in the Northern Song Dynasty, an emissary went out and saw a beautiful woman who looked fifteen or sixteen years old, holding a stick and reprimanding an old woman who looked eighty or ninety years old. He stepped forward to dissuade her and asked the woman, "Who is this old woman in your family? You are still young, how can you beat her old man's house? After listening to a smile, the beauty solemnly announced to the emissary, "She is my great-granddaughter, and I punished her because she refused to take anti-aging drugs, which made her grow old before she got old and walk hard. The messenger couldn't help but be surprised and quickly asked, "How old are you this year? There will be such a big great-granddaughter? " The beauty replied: "I am 372 years old this year. The messenger asked again, "You must have a way to preserve your health after living for so long. I don't know what medicine to take to live longer. " The woman said, "The good medicine is Lycium barbarum. From this record, we can also see the magical effect of Lycium barbarum in preventing aging and prolonging life.

Lycium barbarum is a dried and mature fruit of Lycium barbarum in Ningxia, Solanaceae. Lycium barbarum was first seen in Shennong Materia Medica Classic and was listed as the top grade. "Shennong Materia Medica Classic" records: "Lycium barbarum tastes bitter and cold, cures internal evils of the five internal organs, clears away heat and quenches thirst, strengthens bones and muscles for a long time, and keeps people healthy." Outline: "Nourishing kidney, moistening lung and improving eyesight."

Many people like to soak Lycium barbarum in water, wine or soup. Chinese medicine has long said that eating Lycium barbarum can "strengthen bones and muscles and resist cold and heat", so it is often used as a tonic and anti-aging drug.

Many people don't know that eating Lycium barbarum often can help beauty beauty. This is because Lycium barbarum can improve the ability of skin to absorb oxygen, in addition, it can also play a whitening role.

Although Lycium barbarum has good nourishing and therapeutic effects, it is not suitable for everyone. Because its warm-up effect is quite strong, people with colds, fever, inflammation and diarrhea had better not eat it.

The people who are most suitable for eating Lycium barbarum are people with weak constitution and poor resistance. And we must persist for a long time, and eat a little every day to be effective.

Don't overdo any tonic, and Lycium barbarum is no exception. Generally speaking, it is more appropriate for healthy adults to eat about 20 grams of medlar every day; If you consider the effect of treatment, it is best to eat about 30 grams a day. Now many animal experiments about the toxicity of Lycium barbarum prove that Lycium barbarum is a very safe food, which contains no toxin and can be eaten for a long time.
