Brown Listerine is marketed as a mouthwash, but people have found many other uses for it, from applying it to armpits to using it on toes. Some believe its ingredients might help with psoriasis patches, although there’s no evidence to support this.
Listerine has been around since the 1800s, originally used to prevent infections after surgeries and even to treat dandruff. Eventually, people discovered it could kill bacteria in the mouth, which led to its popularity as a mouthwash.
A study examined the antiseptic properties of Brown Listerine and Cool Mint Listerine against various microorganisms, including MRSA, Candida albicans, HIV, and oral bacteria. A 30-second exposure to Listerine was effective in significantly reducing these microorganisms. The mouthwash is believed to kill germs that cause oral infections.
Listerine’s active ingredients include four essential oils found in plants, which may have antibacterial and antiviral properties. Some studies suggest that eucalyptus oil and thymol can help heal wounds, potentially aiding in treating certain skin conditions.
However, there’s no research proving Listerine’s effectiveness against psoriasis. Psoriasis is an inflammatory condition caused by immune cells, not typically associated with infections or bacteria. Therefore, a germ-fighting product like Listerine is unlikely to help.
While the essential oils in Listerine might slightly moisturize the skin, a good moisturizer would likely be more effective. Listerine contains alcohol, which can dry out the skin over time, so keeping the skin hydrated is crucial for those with psoriasis.
Using Listerine as intended poses no risk, and it might help with skin issues involving germs. The menthol and other ingredients could provide temporary relief from itching, but it’s unlikely to improve psoriasis and might cause more problems over time.
If psoriasis symptoms are bothersome or worsening, it’s best to consult a doctor for more effective treatments. Cosmetic mouthwashes can freshen breath and help remove food particles, reducing tooth decay risk. However, they don’t have long-term biological effects beyond their immediate use.
Therapeutic mouthwashes, available over-the-counter or by prescription, can help reduce plaque, gingivitis, and bad breath, and prevent tooth decay. They are categorized based on their purpose, such as antiseptic or anti-cavity. Some require a prescription, like certain fluoride or antibacterial rinses.
