What should I do if I experience skin itching or allergic reactions after eating ginkgo nuts?

When skin itching or allergic reactions occur after consuming ginkgo nuts, the following measures are recommended: 1. Immediately stop eating ginkgo nuts upon noticing symptoms such as skin itching to avoid further exposure to the allergen. 2. Take oral antihistamine medications, such as cetirizine hydrochloride tablets or loratadine tablets. These drugs can suppress histamine release and alleviate symptoms of allergic reactions. 3. If necessary, apply topical ointments under a doctor's guidance to relieve skin itching and inflammation. 4. For localized swelling, apply cold compresses using a towel-wrapped ice pack. This helps constrict capillaries, reduce exudation, and ease swelling. 5. Keep the affected skin area clean and dry, avoiding soap or other chemical cleansers that may irritate damaged skin.
