Problems solved by technology

[0005] In the treatment of allergic dermatitis, topical antiallergic drugs are one of the main treatments, including: glucocorticoids, although they can resist allergies and relieve itching to a certain extent, but long-term topical use has adverse effects such as local skin atrophy, infection, and abnormal pigmentation. In addition, there are other non-glucocorticoid drugs, such as calcineurin inhibitors and various traditional Chinese medicine monomers or compound ingredients, although they have certain effects , there are more or less defects such as weak curative effect, high price and local stimulation
Overall, anti-allergic dermatitis topical drugs are not effective for a considerable number of patients with atopic dermatitis

Embodiment 1

[0014] The application of limonene in the preparation of anti-allergic dermatitis drugs, the following detailed analysis of limonene on the impact of atopic dermatitis through animal experiments.

[0015] 1. Experimental group:

[0016] ① Normal control group

[0017] ②Model group

[0018] ③Limonene low dose group (100mg / kg / d)

[0019] ④Limonene medium dose group (200mg / kg / d)

[0020] ⑤Limonene high dose group (400mg / kg / d)
