As we enter winter, people who are prone to allergies can breathe a sigh of relief as there is less pollen in the air and their noses and skin are not so itchy. However, there are still people who are “charmed” by the scent of flowers, and the reason is the packets of fragrant dried flower fragrance packets. Compared to perfumes and air fresheners, dried flower fragrance packets are favored by some people because they are easy to carry and can give off a fresh and natural fragrance for a long time. Some people scatter it in the corners of their homes, others put it in their closets …… but soon find that allergy symptoms appear. Some people think that although it is processed dried flowers, there will still be residual pollen, and it is best for people with allergies to stay away. Dr. He Zhixin, deputy chief physician of the Department of Dermatology at Peking Union Medical College Hospital, believes that dried flower fragrance packets may indeed cause allergies, but they are generally not caused by pollen because the dried flowers will basically have no more pollen after treatment. The perfume sprayed on the dried flowers is more suspicious. Some of the dried flowers smell unnaturally, and the smell is the taste of chemical perfume, and may even be poor quality perfume, which is more pungent. Allergic people are best not to contact the chemical fragrance too strong, even from the non-allergic people should also be careful to be careful. It is understood that the source of the scent of dried flower products is indeed not the petals themselves, it is a combination of dried flowers and melon fruit shells and other plants together to remove the original flavor, and then fumigated with pure natural plant fragrance oil. Although manufacturers claim that these aromatic oils have antiseptic, antiviral, insect repellent, antioxidant, stress relieving, and even hypotensive and asthma regulating effects, but allergic people should first ensure that away from all possible allergens, not to mention that it is difficult for consumers to distinguish whether the production process of dried flower fragrance package is scientific and environmentally friendly. ”Allergy lovers should not let down their guard against other forms of “flowers” just because they have avoided the summer and fall seasons when flowers are in full bloom, nor should they be confused by simple appearances and let go of the real allergens.
