Patients with rhinitis try to eat less or no garlic, especially raw garlic, mainly for the following reasons: 1. Raw garlic is a spicy, stimulating food, and patients who eat too much raw garlic are prone to congestion of the nasal mucosa, which can easily lead to changes related to runny eyes. At this time, it may aggravate nasal congestion, aggravate the symptoms of rhinitis and increase nasal secretions. 2. Garlic is also a food that can easily stimulate patients to get on fire, if the nasal mucosa is dry, mucosal erosion, ulceration, or even nasal bleeding when suffering from rhinitis. At this time, eating garlic raw can easily aggravate the dryness and erosion of the nasal mucosa due to fire. Therefore, patients with rhinitis should not eat raw garlic as much or as little as possible, but it is okay to eat raw garlic in moderation. Patients with rhinitis should try to apply rhinitis medication regularly under the guidance of a doctor for better results, and try to eat a light, liquid diet during normal times.
