You may have seen this traditional remedy: soak half an onion in white vinegar for 24 hours, place it over a wart, and cover it with a bandage.
🧅🍶 The idea is that the acidic vinegar may soften the thickened skin, while onion contains sulfur compounds and other plant chemicals with antimicrobial activity.
But there’s an important problem: there is not good clinical evidence that onion soaked in vinegar reliably removes warts. Strong vinegar or prolonged contact can also irritate or chemically burn the surrounding skin.
🧬 Why do warts appear?
Most common warts are caused by certain types of human papillomavirus (HPV). They often disappear on their own as the immune system clears the infection, although this can take months or longer.
🔬 Evidence-based options for common warts include salicylic acid preparations and, when appropriate, treatments performed by a healthcare professional such as cryotherapy.
⚠️ Don't try home acid remedies on the face, genitals, damaged skin, or areas with poor circulation. If a growth is painful, bleeding, rapidly changing, or you're not sure it's actually a wart, have it assessed before treating it.
✨ A traditional remedy can be interesting without being proven medicine. When it comes to skin growths, correctly identifying what you're treating is the first step.
