Artemisia allergy is usually more serious in August and September. Artemisia allergy is caused by the inhalation of pollen particles of artemisia grass. Artemisia grass blooms at the beginning of autumn every year, and the pollen will spread out with the air after blooming. Allergic reactions need to be treated promptly. Generally, after the weather turns cooler, artemisia will wilt naturally and the pollen particles in the environment will decrease, which means the allergens will disappear, and at this time, the allergy symptoms of artemisia allergy sufferers will also disappear. If the allergic reaction does not disappear after the end of the high artemisia period, oral antihistamines, such as loratadine, cetirizine or glucocorticoids, need to be taken under the guidance of a professional doctor for treatment. In daily life, attention should be paid to drinking more water, eating a light diet, reducing the consumption of spicy and stimulating foods, and eating more nutritious fruits and vegetables. You should also avoid the use of cosmetics with strong irritation, try not to go to places where artemisia grows abundantly, and try to wear a good mask when you go out to prevent allergy caused by contact with artemisia again.
