Longan, the correct name is longan, is not the same thing as lychee. Longan is warm in nature, and excessive consumption will cause internal heat. The same goes for lychees.

In addition, eating too many lychees is likely to cause lychee disease. The essence of litchi disease is a kind of "hypoglycemia". Lychees contain a large amount of fructose. After fructose is quickly absorbed into the blood through the capillaries of the gastrointestinal mucosa, the fructose must be converted into glucose by the invertase in the liver. can be directly used by the human body. If you eat too much lychee, too much fructose will enter the human blood, and the invertase that "reforms" fructose will be in short supply. In this case, a large amount of fructose fills the blood vessels but cannot be converted into glucose that can be used by the body. At the same time, eating too much lychees affects appetite, depriving the human body of necessary nutritional supplements, resulting in insufficient glucose in the human blood, which can lead to lychee disease.

The usual clinical manifestations of litchi disease are: dizziness, palpitations, fatigue, pale complexion, and clammy skin. Some patients may also experience thirst and hunger, or abdominal pain and diarrhea. Some severe patients may suddenly become comatose. , paroxysmal convulsions, weak and fast pulse, constricted pupils, irregular breathing, intermittent or sigh-like, blue-grey complexion, cyanosis of the skin, arrhythmia, decreased blood pressure, etc. Once litchi disease occurs, active treatment should be taken. For those who only have mild symptoms such as dizziness, fatigue, and sweating, they can take glucose water or white sugar water to correct hypoglycemia and supplement the glucose necessary for life. If severe "lychee disease" occurs such as convulsions, collapse or shock, they should be sent to the hospital for treatment in time. Intravenous injection or intravenous infusion of high-concentration glucose can quickly relieve symptoms and leave no sequelae after cure.

Although longan is delicious, it is easy to get angry. Usually, each person should not eat more than 6 taels of longan per day.

Excessive consumption of longan causes "longan disease". The main symptoms are: diarrhea, nosebleeds, oral ulcers, inflammation of the oral mucosa, constipation, etc.

Longan is a nutritious fruit that can increase appetite, but at the same time it can easily make people "get angry". Therefore, it is not advisable to eat too much of these fruits, especially children, the elderly and those suffering from chronic tonsillitis, pharyngitis, "deficiency of fire", constipation, diabetes and other diseases. They should not eat or eat less "longan" and other " "Inflammation" type of fruits. Citizens without such symptoms should control the amount of longan consumed in a day to about 4 taels, and the maximum daily consumption should not exceed 6 taels.
