Natural Nebulizer Solutions: Understanding the Benefits and Risks
We have all been sick from time to time, but we all hope to avoid becoming sick again. Using natural substances in a nebulizer can help reduce the risk of contracting a contagious illness and can help you recover faster if you do get sick. Certain substances should not be used in a nebulizer due to their high risk of side effects, but others are beneficial.
A nebulizer is a machine that creates a fine mist that is inhaled using a mask. The contents of the mist is dependent upon what the nebulizer is filled with. It’s commonly used for medications, but natural substances can be placed in the machine, too. Make sure you keep the device and components clean to avoid causing illnesses (Cleveland Clinic, 2019).
While nebulized hydrogen peroxide may offer protection from illnesses, the risks outweigh the potential benefits. One study found that nebulized hydrogen peroxide was very effective in preventing the spread of Covid (Agrawal, et. al., 2022). Some other sites claim that nebulized hydrogen peroxide is effective in shortening the length of viruses and protecting against the development of viral infections (East Valley Naturopathic Doctors, 2020; Riordan Clinic, n.d.). However, one of these sites clearly warns to consult a professional, since mixing the proper ratio is vital to prevent severe side effects (Riordan Clinic, n.d.). In 2021, the U.S. government issued a warning against the use of hydrogen peroxide in a nebulizer on the basis of severe lung irritation (AAFA Community Services, 2021). An article summarizing hydrogen peroxide nebulizers concluded that they’re unsafe and can lead to severe side effects, including lung edema and irreversible damage (Chase, 2024b). A case report detailed an instance of hospitalization with inhalation pneumonitis as a result of using hydrogen peroxide in a CPAP machine (Manfra, 2023). Under professional guidance, hydrogen peroxide nebulization may be safe in the right dilution, but there is insufficient evidence of benefits to outweigh the proven risk for serious injury (Sissons, 2022).
Silver has shown promising benefits, but it does come with some risks. A 2023 study found nebulized nanosilver to be beneficial for fungal sinusitis, pneumonia, and Covid (Nadworny, 2023). Another study revealed that 2mg daily of nebulized silver electrolysis solution reduced COPD exacerbations (Lobanov, 2020). At a low dose, silver nanoparticles did not have any significant cytotoxic or inflammatory effects when exposed to the air-liquid barrier of the respiratory tract (Herzog, 2013). However, long term exposure to silver poses a potential health hazard (Theodorou, 2014). It’s important to note that many studies on silver inhalation have been done using nanosilver, which is different from colloidal silver. Nanosilver nebulization can be beneficial in small occasional doses, but colloidal silver can have serious side effects such as skin staining and organ damage (Chase, 2024a).
Some people have suggested using iodine in a nebulizer, but there is insufficient evidence to support the safety or efficacy of this treatment. Iodine is generally considered a lung irritant and at high exposures can cause lung edema, which is a serious medical emergency. It could also cause organ damage (New Jersey Department of Health, 2016). It would be unwise to use iodine in a nebulizer, at least until further research is done.
Nebulized saline can be an effective way to treat and prevent illness. Saline can be used to open airways, thin mucus, and make mucus easier to clear from the lungs (Nebology, 2025). A 2020 study found that using an isotonic saline solution in a nebulizer reduced the severity of symptoms and potentially prevented life threatening pulmonary obstruction (Barski, 2020). Nebulized hypertonic saline solution can prevent illness by increasing the clearance of mucus, which carries pathogens out of the respiratory tract (PARI, n.d. (a)). Overall, isotonic saline solutions are good for supporting the natural mucosal lining in the respiratory tract when you have a dry cough or would like to prevent illness and hypertonic saline solutions work best for clearing excess mucus (PARI, n.d. (b)).
Adding xylitol to your nebulizer can help prevent illness. Nebulized xylitol was well-tolerated in a trial involving mice and humans. Xylitol enhances innate immunity by lowering salt content of the airway surface (Durairaj, 2004). A study on rats concluded that long term inhalation of xylitol was safe and well tolerated, so xylitol nasal sprays and nebulizers can be used throughout the cold and flu season (Tian, et. al., 2022). Another study done on beagles confirmed this conclusion and stated that “inhaled xylitol is safe for clinical administration” (Reed, 2012). Xylitol is likely safe for most people, since a single dose was safe for people with cystic fibrosis in a 2007 study (Durairaj), but it’s always wise to consult your doctor first. Xylitol restores the proper level of moisture to the nose, which is necessary for immune function. Xylitol has antibacterial and antiviral action that works by blocking the receptor sites on the cells, and thereby doesn’t risk toxicity to the cell or cause antibiotic resistance (Common Sense Medicine, 2023). Ideally, xylitol nebulizers or nasal sprays should be used several times per day during cold and flu season, since it lingers in the airway surface liquid for 3 hours after treatment (Durairaj, 2006).
Do not use hydrogen peroxide or iodine in a nebulizer, as the risks far outweigh the benefits of this treatment. Nebulized xylitol and saline are safe and effective for prevention of illness and enhanced recovery. Nebulized nanosilver should only be used in cases of severe illness, as it can have severe side effects when used for an extended period or in high concentrations. Make sure you follow the instructions that come with your nebulizer and keep it clean to prevent injury and illness.
