This is hardly new; people have been putting strange things in nasal rinses for some time now and garlic is a tried-and-true favorite. Garlic does have some medically valid uses. These studies have shown that garlic taken orally may improve insulin in people with diabetes, slightly lower cholesterol, and reduce blood pressure in people with hypertension. When it comes to home remedies, people have historically used garlic as an antiseptic, antibacterial, and antifungal agent, though these claims are not widely supported by research. But taking a garlic supplement and sticking raw garlic up your nose are two very different things.
New York-based board-certified dermatologist Whitney Bowe, MD, weighed in on the viral trend.
In her own reaction video, she explained: “Guys, this is actually not safe. What’s happening is the garlic is actually triggering something called contact dermatitis and the mucosa is trying to protect itself by secreting tons of mucus. It’s creating swelling.”
For those tempted by this smelly “remedy,” a few drops of essential oil in a steamy shower is a much more pleasant (and significantly less gross) way to treat congestion.
