Is lychee heaty or cooling?

Generally speaking, lychee is considered a heaty fruit, and the detailed explanation is as follows:

Lychee has a warm nature, and moderate consumption can help individuals with a cold constitution replenish energy and alleviate symptoms such as cold hands and feet and sensitivity to cold. Healthy individuals can consume 5-8 lychees at a time, utilizing their warming properties to promote blood circulation, supplement vitamins and sugars, and serve as an energy source particularly suitable for colder weather, generally without causing adverse effects.

Individuals with a heaty constitution are prone to internal heat, and consuming lychees may exacerbate symptoms like dry mouth, sore throat, and thirst. Those suffering from mouth ulcers, acne, or currently experiencing a feverish cold should avoid lychees, as their consumption may increase internal heat, leading to worsening or recurrence of illness. Additionally, excessive consumption of lychees—more than 10 at one time—may trigger "lychee disease," causing discomfort such as hypoglycemia and dizziness. In such cases, intake should be strictly controlled or avoided altogether.

In daily diets, attention should be paid to balancing food properties, selecting ingredients according to individual constitution, and maintaining the body's yin-yang equilibrium.
