Plant-Derived Antiallergic Active Ingredients for Food Allergies

The pharmacological use of plant-derived active compounds, such as their antitumor, antiallergic, antiviral, and antioxidative properties, has garnered significant attention. The allergy epidemic poses a serious threat to public health and safety worldwide. Plant-based active ingredients exhibit strong antiallergic properties, which makes them a valuable resource for the creation of antiallergic drugs. This chapter introduced the latest developments in plant-derived actives’ antiallergic efficacy. It also contains information on cellular and animal models used to study plant-derived antiallergic active ingredients. To give a theoretical foundation for the research and application of these active ingredients as antiallergic products, the present problems and potential future prospects in this sector are also covered. This chapter primarily addresses plant-derived substances with antiallergic activity categorized according to three aspects, polyphenols, polysaccharides, and others, and will serve as a reference for readers engaged in the screening of active substances and drug development.
