Urticaria and angio-oedema are a symptom complex covering a wide range of clinical disorders. Specific types are now well described, and it appears that many cases of idiopathic chronic urticaria which make up the vast majority of patients referred for assessment are due to intolerance to natural salicylates, preservatives and colouring agents. There is, therefore, an urgent need for legislation to enforce the clear identification of these chemicals in processed food and drugs.
荨麻疹和血管性水肿是一组症状复合体，涵盖了广泛的临床病症。现在已经对特定类型有了很好的描述，而且构成绝大多数被转诊进行评估的患者的特发性慢性荨麻疹病例，似乎是由于对天然水杨酸盐、防腐剂和着色剂不耐受所致。因此，迫切需要立法来强制要求在加工食品和药品中明确标识这些化学物质。
