Patients with allergic rhinitis are advised to eat little or no garlic, especially raw garlic, because garlic is a spicy and stimulating food, and after eating raw garlic, it can easily induce nasal dryness. In addition, because garlic is a spicy and stimulating food, it is easy to induce congestion in the nasal mucosa after eating garlic, resulting in faster local blood flow and thus aggravating the symptoms of rhinitis. Clinically, it is best for patients with allergic rhinitis to eat a light diet, eat more vegetables and fruits, try to avoid foods that can easily induce allergies, and do not eat spicy and stimulating foods that can easily get on fire, wash their faces with cold water often, and exercise regularly to improve their immunity. Of course, the above are preventive and health care measures, but the important thing is to use medication, clinically you can use nasal spray hormone and antihistamine nasal spray, oral anti-allergy drugs for comprehensive symptomatic treatment and treatment.
