Litchi is a unique fruit in southern China. Litchi is warm and dry, and it is best to eat less (preferably within 0.25 kg at a time) for those with yin deficiency and strong fire. People with chronic tonsillitis and pharyngolaryngitis, eating more lychee will aggravate the deficiency fire; After eating fresh litchi, allergic people will have allergic symptoms such as dizziness, nausea, abdominal pain, diarrhea, rash and itching. Eating too much litchi, especially on an empty stomach, may cause hypoglycemia, also known as litchi disease. It is best not to eat a lot of lychee continuously, but to drink a little salt water or herbal tea before and after eating lychee. Mung bean water, melon water and Radix Rehmanniae soup also have good curative effects. For children, litchi is the same as mango, longan and other fruits. Children with heavy internal fire had better not eat, and normal children should eat as little as possible. For the elderly, elderly people with constipation should try not to eat; Especially patients with liver disease, kidney disease, diabetes and gastrointestinal diseases should be more cautious.

Litchi (scientific name: litchi Sonn. ) is a subtropical fruit tree, evergreen tree, about 10 m high, native to southern China. The peel is scaly, bright red and purplish red. When the pulp is fresh, it is translucent and fatty, delicious, but not storable. Litchi, together with bananas, pineapples and longan, is called "the four major fruits in South China". Litchi is famous for Yang Guifei's love of eating, which made Du Mu write a famous sentence "The world of mortals rides a princess and laughs, but no one knows it is litchi". Litchi is hot, and it is easy to get angry if you eat too much, which will cause "litchi disease". Solid wood, dark reddish brown, elegant texture, corrosion resistance, has always been a first-class material.

At the same time, it has the effects of strengthening the brain, strengthening the body, stimulating appetite and strengthening the spleen.
