Dwarf ragweed, Artemisia selengensis, Allergy

Artemisia, a woody plant, is edible and often used as a seasoning. There are many types. Includes Artemisia selengensis, Artemisia argyi, etc. Skin allergies to dwarf ragweed and Artemisia selengensis can cause allergic rhinitis.

Allergic rhinitis is common in the western part of Inner Mongolia Autonomous Region. The main allergens are Artemisia and dwarf ragweed, and the allergic symptoms caused by them have many clinical manifestations. Allergic rhinitis has a strong regional characteristic, but why has there been a concentrated outbreak trend in Inner Mongolia Autonomous Region in recent years?

Pathological reflection

1. From the perspective of basic immune response, allergic rhinitis is an inflammatory sensation mediated by antigen IGE. When the body comes into contact with allergens, an antigen called IGE is produced, which is adsorbed on the surface of tissue mast cells and alkaliphilic granulocytes, and the body is in an allergic reaction state. When the body comes into contact with the same allergen again, the allergen will combine with IGE, causing mast cells and alkaliphilic granulocytes to degranulate, releasing bioactive substances such as nitrosamines and leukotrienes. These substances act on the corresponding tissues and cause allergic symptoms.

2. Because allergic rhinitis has the above-mentioned pathological characteristics, its onset period is the same as the growth period of plants such as Artemisia, with concentrated outbreaks from June to October each year, with July and August being the peak periods. By the end of September, the patient's condition will be significantly improved.

Symptoms of allergies

1. The main symptoms of patients with allergic rhinitis are runny nose, nasal congestion, sneezing, tearing, etc. It can also cause inflammation of the five senses such as otitis and conjunctivitis.

2. Because this symptom is similar to a cold, many people initially mistake rhinitis for a cold and delay treatment, leading to the occurrence of other complications. Director Yang said that based on many years of clinical medical observations, most patients with allergic rhinitis have combined asthma, and allergic rhinitis and allergic asthma are very similar in the medical immunological pathogenesis. Allergic rhinitis is one of the high-risk factors for asthma, and severe cases can seriously endanger life.

heal

At present, there is no very effective treatment for allergic rhinitis in medicine, and the patient's pain can only be relieved through some drugs. Because most drugs for treating allergic rhinitis are hormones, many patients give up treatment.

These drugs always suppress the occurrence of symptoms. Once the drug is discontinued or drug resistance is developed, the condition will still recur or even worsen, so patients need to carefully choose medication for treatment.

Allergen safety protection

Allergic rhinitis, prevention is fundamental. The nasal air purifier for Haze Star uses medical silicone rubber, which fits tightly to the face and has 100% airtightness. In addition, the gill-flap filter module can filter out 99% of allergens. The combination of the two can effectively reduce the probability of illness in patients. In this way, even in areas with a lot of wormwood, wearing the mask does not have to worry about rhinitis.

At the same time, wearing a nasal mask can form an extranasal cavity outside the nose, which can effectively warm and humidify the air and keep the nostrils moist.
