Efficacy of Auricular Acupressure Combined With Antihistamines in Patients With Wind-Heat Type Urticaria.

The purpose of this clinical trial is to evaluate the efficacy of auricular acupressure combined with an antihistamine (Loratadine) in treating patients diagnosed with Wind-Heat type urticaria. Participants will be randomly assigned to either the intervention group or the control group. The purpose of this clinical trial is to evaluate the efficacy of auricular acupressure combined with an antihistamine (Loratadine) in treating patients diagnosed with Wind-Heat type urticaria. Participants will be randomly assigned to either the intervention group or the control group. The main questions the study aims to answer are: * Does true auricular acupressure combined with Loratadine reduce urticaria symptoms (measured by the Urticaria Activity Score - UAS) more effectively than sham acupressure with Loratadine? * Does the intervention improve the patients' quality of life (measured by the Dermatology Life Quality Index - DLQI) better than the control treatment? * Are there any adverse effects associated with the auricular acupressure treatment during the intervention period? Participants will: * Take a standard daily dose of oral Loratadine (10mg). * Visit the clinic once a week for 4 weeks to have Vaccaria seed patches applied to their ear (either true therapeutic points or sham points, depending on their assigned group). * Self-stimulate the acupoints by pressing the patches for 1 to 2 minutes, 2 to 3 times a day at home. * Record their daily urticaria symptoms (wheals and pruritus) using the Urticaria Activity Score (UAS). * Complete the Dermatology Life Quality Index (DLQI) questionnaire at the beginning and at the end of the 4-week study period.
