1. Kumquat is rich in fruit acid. Eating too much will stimulate the gastric mucosa, stimulate the intestine and cause discomfort. Therefore, kumquat lemon honey tea is not suitable for drinking. 2. After drinking kumquat lemon honey tea, avoid contact with strong ultraviolet rays. Because lemon is a photosensitive food, skin inflammation such as erythema, papules and edema will appear after excessive consumption of lemon and sun exposure. 3. Do not use boiling water when brewing kumquat lemon honey tea, because honey contains enzymes, which will release excessive hydroxymethylglycolic acid when encountering boiling water and destroy the nutrients in honey. It is best to brew with warm water.
