Patients with skin allergies can generally eat grapefruit. From the perspective of Chinese medicine, grapefruit is considered cool in nature with a sweet and sour taste. It has the effects of aiding digestion, transforming phlegm and stopping coughs, harmonizing the stomach and regulating qi, as well as detoxifying alcohol. Clinically, it is rare to encounter patients allergic to grapefruit, so it is usually safe for people with skin allergies to eat grapefruit, unless they are absolutely allergic to it.
