“…There are many mite control methods, such as washing bedding in hot water, encasing mattresses and pillows in allergen-impermeable covers or tightly woven-material covers, maintaining room relative humidity below 50%, removing carpets, and vacuuming regularly (Jeong et al 2006;Miller et al 2007;Vyszenski-Moher et al 2002). Abidin and Ming (2012) also demonstrated that a commercial air ionizer kills HDMs and can be used to reduce natural mite populations on exposed surfaces. In addition, various chemicals such as benzyl benzoate, DEET, and dibutyl phthalate have been used to control HDM populations (Suhaili and Ho 2008;Uehara et al 2006).…”

Essential oils obtained from three medicinal plant species, namely, cinnamon (Cinnamomum bejolghota [Buch.-Ham.] Sweet), citronella grass (Cymbopogon nardus Rendle), and clove (Syzygium aromaticum [L.] Merr. & L. M. Perry), were sprayed on allergenic materials (house dust plus spent mite medium produced by the European house dust mite, Dermatophagoides pteronyssinus [Trouessart]) to evaluate the effects of the oils on allergen levels. A 1% solution of each essential oil in 95% ethanol was sprayed on the allergenic materials (which contained about 50 µg of allergen per gram of material), and 95% ethanol, water, and untreated allergenic materials were used as controls. The sprayed materials were allowed to stand for 48 h, and then allergen levels were analyzed by means of an enzyme-linked immunosorbent assay method. The results showed that the essential oil from C. bejolghota reduced the amount of allergen 99.4%, and the essential oils from C. nardus and S. aromaticum reduced the amounts by 77.1% and 74.0%, respectively. In contrast, the 95% ethanol control reduced the amount of allergen by only 9.8%.

“…House dust mites have been removed from our living environment using a variety of approaches, including high-temperature steam cleaning, microfibers, air ionizer, high-efficiency particulate air filtration (HEPA) vacuum cleaners, air purification, humidity control (below 50%), and chemical synthetic agent sterilizing [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. Phthalthrin cyclopropanecarboxylate, benzyl benzoate, and N,N-diethyl-m-toluamide [ 30 ] are the major chemical components of regularly used insecticides.…”

House dust mite (HDM) is a globally ubiquitous domestic cause of allergic diseases. There is a pressing demand to discover efficient, harmless, and eco-friendly natural extracts to inhibit HDM allergens that are more likely to trigger allergies and challenging to be prevented entirely. This study, therefore, is aimed at assessing the inhibition of the allergenicity of major HDM allergen Der f 2 by todomatsu oil extracted from residues of Abies Sachalinensis. The inhibition was investigated experimentally (using enzyme-linked immunosorbent assay (ELISA), surface plasmon resonance (SPR), and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE)) and in silico using molecular docking. The results showed that todomatsu oil inhibits the allergenicity of Der f 2 by reducing its amount instead of the IgG binding capacity of a single protein. Moreover, the compounds in todomatsu oil bind to Der f 2 via alkyl hydrophobic interactions. Notably, most compounds interact with the hydrophobic amino acids of Der f 2, and seven substances interact with CYS27. Contrarily, the principal compounds fail to attach to the amino acids forming the IgG epitope in Der f 2. Interestingly, chemical components with the lowest relative percentages in todomatsu oil show high-affinity values on Der f 2, especially β-maaliene (−8.0 kcal/mol). In conclusion, todomatsu oil has been proven in vitro as a potential effective public health strategy to inhibit the allergenicity of Der f 2.
