These compounds include osthole, forsythoside B, and the isomers isochlorogenic acid A and isochlorogenic acid B. Osthole exerts an inhibitory effect on TRPV3 through allosteric competitive inhibition, reduces the expression of inflammatory factors TNF-α and IL-6 in animal atopic dermatitis models, and alleviates pruritus in the skin of AD mice. This evidence concerns the gene TRPV3 and atopic eczema.
