There are four common species, namely house dust mite, dust mite, cosmomite and polychaete mite. House dust mite is the main mite in humid climate. Fungi are also one of the allergens in indoor air, such as Penicillium, Aspergillus, Alternaria, etc. Pollen and grass powder are the most common outdoor allergens causing asthma attack. The results show that tree pollen often causes asthma in spring, while grass pollen often causes asthma in autumn.

The common allergens are cereal powder, flour, animal fur, wood, silk, hemp, kapok, feed, mushroom, rosin, reactive dye, ethylenediamine, etc. The mechanism of action of low molecular weight allergens is still unclear. High molecular weight allergens may sensitize patients through the same allergic mechanism as allergens and cause asthma attack.

In the former, allergy to biological products is the most common, while in the latter, it occurs in sympathetic blockers and enhancing parasympathetic agents.
