A nasal spray called Thymogen can kill a common cold-like virus in lab tests, starting at a certain strength, which might help fight off this virus in people.
Zinc lozenges might help with colds, but it depends on how much zinc you take and what type of zinc it is. Taking more than 75 mg a day works, while less doesn't, and acetate zinc works better than...
Some people get a bad taste from zinc lozenges when using them for a short time to treat colds, but there's no proof they cause any lasting harm.
Different ingredients in zinc lozenges can change how well they work, even if the amount of zinc is the same, because some ingredients stick to the zinc and make it harder for your body to use it.
Taking certain zinc lozenges (not the acetate kind) in high daily doses might shorten how long you have a cold by about one-fifth, but different brands or types seem to work differently based on...
Taking zinc lozenges with less than 75 mg per day doesn't seem to shorten how long a cold lasts, based on studies comparing them to fake pills. It might only work if you take enough.
Taking zinc lozenges with a certain ingredient can shorten how long you have a cold by almost half, according to studies on people with real colds.
For woodworkers with stuffy or irritated noses, rinsing the nose with salt water is a safe, cheap, and helpful option that doesn't cause many problems.
More than 50% of woodworkers kept choosing to use a nasal rinse on their own after a year, showing they found it easy and comfortable to use.
Woodworkers who rinsed their noses daily with a simple saltwater solution they made at home for two months said their stuffy noses and other nose problems got a lot better.
Breathing in wood dust can irritate and cause cancer in your nose, and it gets stuck there because it stops your nose from cleaning itself out. So, washing your nose out with water (nasal lavage)...
Salt fights viruses by working inside your cells while the virus is copying itself, not by directly killing the virus or stopping it from entering cells.
When scientists block a certain enzyme in non-blood cells with a chemical called 4ABAH, it stops salt from having its virus-fighting effect, showing that this enzyme is needed to turn salt into a...
Certain body cells make more of a chemical called hypochlorous acid when they're fighting a virus and there's extra salt around, which can be measured with special tools.
Salt's ability to fight viruses depends on how chloride moves inside cells, not sodium. When chloride movement is blocked, salt can't stop viruses, but blocking sodium movement doesn't change salt's...
Adding more salt to the liquid that cells grow in makes it harder for many viruses to copy themselves inside those cells, and the more salt you add, the less the viruses copy themselves, without...
When certain chemicals are blocked in rats, it seems to slow down the growth of new blood vessels, which might explain how this process works.
Honey might help reduce inflammation in rats by blocking certain chemicals that cause swelling and blood vessel growth, suggesting it could calm down inflammation.
Honey might help reduce swelling and blood vessel growth in inflamed areas, based on a test in rats, which could mean it has properties that fight inflammation and block new blood vessels from...
Scientists think that a certain virus gets turned off more by chloride (like in salt) than by sodium (another part of salt), meaning chloride might be the key ingredient stopping the virus.
Scientists found that a virus called Mengo stays just as strong and dangerous when mixed with salt water or plain water and kept warm, because it still killed mice in tests.
In studies where people tried zinc gluconate lozenges, most just noticed a bad taste or some mouth irritation, but nothing serious happened.
Taking zinc gluconate lozenges when you have a cold might help you get better about 7 days faster than if you didn't take them, according to a study.
Taking zinc lozenges every few hours might help people get over a cold faster, with more people feeling better in a week compared to those who don't take them.
