Patients who have wounds should try not to eat flower nails, especially those caught from the sea, which can cause irritation to the wound, prompting the capillaries at the wound to open up and not heal easily. Patients can eat a small amount of freshwater flower nails, and they must be cooked when using them to avoid bringing bacteria into the body when using them. The flower nail itself has the effect of nourishing the yin, tonifying the kidneys and moistening the lungs, and lowering cholesterol, so there are some benefits to using it in general. However, patients with wounds should try to eat less hairy foods such as flower nails, beef and mutton, seafood, etc. They should also eat less raw, cold and stimulating foods such as coffee and chili. In addition to irritating the wound, it can also easily lead to skin inflammation and allergy. Especially for patients with large wounds, eating flower nail may also increase the risk of wound infection. Patients should try to keep their diet light, they can drink more water appropriately, and eat more foods rich in vitamin C, such as oranges, apples, strawberries and other fresh fruits and vegetables, which help cell metabolism and promote wound healing.
