Scientists Discover That This Specific Artificial Flavoring Could Be Good for You—But Not in the Way You’d Expect

For small cuts, it’s easy to clean the area, slap a bandage on it, and move on with your day. But recovering from larger wounds can be trickier—there’s a risk of infection and slow healing, which can require careful management. Now, a new scientific review suggests something you may already have in your pantry could have untapped wound-healing potential: Vanillin, the organic compound responsible for much of vanilla’s signature taste and smell.

"Vanillin caught our attention because it is a well-known—although quite neglected—relatively accessible molecule with properties that extend beyond its familiar role as a flavoring compound," says Borislav Stoilov, PhD, lead study author and researcher in the College of Medicine and Public Health at Flinders University. Researchers also pointed out that the synthetic version of vanillin may be especially useful as an “abundant and cost-effective” potential solution in the future.

It seems random that vanillin could help with cuts and wounds in the future, but there is science to back this up. However, doctors just don't recommend pouring vanilla extract into your wounds anytime soon. Here's why.

What did the review find?

The review, which was published in the International Journal of Pharmaceutics, analyzed data from existing studies published between 2000 and 2026 that looked at vanillin-containing formulations, biomaterials, drug delivery systems, and therapeutic applications for treating skin ulcers.

After analyzing the data, the researchers discovered a lot about vanillin's potential role in wound healing:

• It has antioxidant, anti-inflammatory, and antibacterial properties that could help address the persistent inflammation, oxidative stress, and bacterial issues that can mess with normal tissue repair in a wound.
• Vanillin has a chemical structure that allows it to interact with polymers that are used to make hydrogels and other wound dressings. This potentially could help to create future materials for wound care.

"The aim is therefore not simply to apply vanillin to a wound, but to incorporate it into a material designed to support the healing process," Stoilov says. Still, he points out that more research is needed to see how well these properties of vanillin actually translate to better healing in patients.

This isn't the first time an artificial flavoring or scent has been used in medicine. "Medicinal herbs and spices, which often have unique flavors and scents, have been celebrated throughout history for their health benefits," says Kelly Johnson-Arbor, MD, a toxicologist at MedStar Health in Washington, DC. Menthol, which is an essential oil isolated from the peppermint plant, is linked with antioxidant, anti-inflammatory, and antibacterial effects like vanillin, Dr. Johnson-Arbor points out.

Eugenol, which contributes to the smell of cloves, also has a long history of use in dentistry, Stoilov says. Cinnamaldehyde, which gives cinnamon its characteristic smell, has been investigated for its antimicrobial properties, too, he says.

Would the treatments smell like vanilla?

Maybe. "Vanillin provides the smell for vanilla—at least some of it, depending on the source—so, yes it is possible," says Jamie Alan, PhD, PharmD, an associate professor of pharmacology and toxicology at Michigan State University. But a lot depends on what you mix vanillin with. "If you mixed it with menthol, you might only be able to smell the menthol," she explains. "If it were just with something like petroleum jelly, then you may be able to smell it."

Would regular vanilla extract do the same thing?

Even though vanilla extract can contain vanillin, doctors don't recommend slapping vanilla extract on your next cut as a way to reap the benefits of this latest study. "According to FDA standards, vanilla extract must contain at least 35 percent ethanol by volume," Dr. Johnson-Arbor says. "Ethanol exposure can reduce wound collagen content and delay wound remodeling, thereby delaying wound healing." Because of this, she says it's "unlikely" that regular vanilla extract will help—and it may even be harmful.

Basically, there's a lot more to be explored when it comes to the role of vanillin in wound healing. "The broader lesson is that molecules familiar to us through their taste or smell can have chemical and biological properties that make them valuable in entirely different fields," Stoilov says.
