Soak fresh litchi in light salt water, and then eat it for about an hour and a half, or drink some chrysanthemum tea after eating litchi. Put fresh litchi in ice water, or sink it in a well or put it in a cold spring (water), and eat it overnight, which can reduce excessive internal heat, and can eliminate dryness and replenish yin.

Longan, whose real name is longan, is not the same thing as litchi. Longan belongs to warm nature, and excessive consumption will cause excessive internal heat.

Longan+chrysanthemum can alleviate the heat of longan through chrysanthemum. People may as well brew a cup of chrysanthemum tea when eating longan, so they don't have to worry about getting angry.
