An asthma organization warned against participating in a social media trend that suggests people can treat or prevent COVID-19 by inhaling hydrogen peroxide through a nebulizer. The Asthma and Allergy Foundation of America (AAFA) said the trend was "concerning and dangerous," according to a blog post on its website. "DO NOT put hydrogen peroxide into your nebulizer and breathe it in," the AAFA's blog said. "This is dangerous!"

… [A] simple, inexpensive, portable device that could produce hydrogen peroxide continuously from just air, water, and electricity, providing a way to sterilize wounds, food-preparation surfaces, and even water supplies. Even at low concentrations, hydrogen peroxide is an effective antibacterial agent, and after carrying out its sterilizing function it breaks down into plain water, in contrast to other agents such as chlorine that can leave unwanted byproducts from its production and use. Hydrogen peroxide is just water with an extra oxygen atom tacked on—it's H2O2, instead of H2O. That extra oxygen is relatively loosely bound, making it a highly reactive...

HYDROGEN PEROXIDE INHALATION FOR C.O.P.D. / LUNG ISSUES I have been using assisted oxygen for the past five or six years. Lately I have been getting fed up with it because my health has been slowly deteriorating. A couple of months ago I bought a 20 MHz Sweep/Function Generator, a Model GB-4000. It is another fantastic machine but as far as helping my shortness of breath. It did some, but just not enough. If I wanted to go outside of the house I still needed to carry oxygen in a tank and be darn sure that I didn't run short,...

Natural bleach 'key to healing' Zebrafish are often used to investigate biological processes A natural bleach produced by the body appears to play a key role in marshalling the immune system to fight off infection and heal wounds. US scientists, working on zebrafish, which have similar genes to humans, found a burst of hydrogen peroxide is released following a tissue injury. This seems to be the signal for white blood cells to converge at the site of damage and begin the healing process. The Nature study may help explain conditions such as asthma. Asthma, obstruction in the lungs and some...

Adding a layer of technology to manual searches of bags and packages taken into the New York City subway, police officials said yesterday that they would begin using mechanized devices that check for conventional explosives. At various stations beginning next week, riders will encounter officials using either hand-held devices that resemble portable vacuum cleaners or larger tabletop ones that look like fax machines. Both work the same way, the police said, by analyzing a cloth swab that is passed over a bag or package to test for the presence of such things as ammonium nitrate or hydrogen peroxide, which was...
