Scallion juice treatment of rhinitis has no scientific basis, clinical is not particularly recommended, mainly for the following reasons: 1, scallion juice has a strong irritation, if the patient will scallion juice drops into the nasal cavity will lead to the mucous membrane in the nasal cavity there is a significant burning sensation, pain and other stimuli, for a long time is easy to induce the mucous membrane of the localized vesicular erosion, ulceration and even the risk of nosebleed, not only can not treat rhinitis, but also lead to the aggravation of rhinitis to induce a nasal bleeding. 2, although the onion juice has a certain anti-inflammatory, anti-inflammatory effect, but the role is very slight, many rhinitis without viral and bacterial infection, so the use of onion juice does not work. In short, rhinitis patients are recommended to regular hospitals for systematic treatment, it is not recommended that the application of onion juice to treat rhinitis, if it is allergic rhinitis can be sprayed with nasal hormones and oral antihistamines and other symptomatic treatment for dry rhinitis can be used for compound menthol nasal drops to nasal drip treatment to keep the nasal cavity moist. Each type of rhinitis can be treated with a combination of medications without the use of onion juice.
