On 17/7, Dr. Ho Ngoc Bao of the Emergency Unit at Tam Anh General Clinic, District 7, reported that a 20-year-old woman named Thanh sought emergency care after chopping about 10 chili peppers without gloves. Her 10 fingertips were blistered and burning. She tried soaking her hands in ice water for an hour, but the symptoms persisted.

Doctors diagnosed her with contact dermatitis caused by capsaicin, the chemical that makes chili peppers hot. This condition is commonly known as a chili burn. The treatment involved pain relievers, anti-inflammatory medication, and a panthenol spray applied directly to the affected area. Panthenol moisturizes and soothes the skin. When applied, it converts to vitamin B5, which is essential for cell regeneration and skin recovery. After about 30 minutes, Thanh's discomfort subsided, and she was discharged.

Thanh said she had handled chilies this way before without incident.

Dr. Bao explained that capsaicin burns differ from thermal, fire, or cold burns. Capsaicin doesn't destroy tissue but intensely stimulates sensory nerve endings, causing a burning sensation. This commonly affects those who handle chilies with bare hands or accidentally touch sensitive areas like their eyes, nose, or mouth with chili residue. In addition to burning, capsaicin can cause redness, itching, and blisters.

Capsaicin is not water-soluble but dissolves in oil. Thus, cold water, even ice, can't soothe the burn. For mild chili burns, Dr. Bao recommends applying fats like cooking oil, milk, or yogurt to neutralize the capsaicin. Leave it on for a few minutes, then wash with soap. For burning in the mouth, consuming milk, rice, or bread can absorb the capsaicin.

If capsaicin gets into the eyes, rinse immediately with clean water or saline solution for at least 15 minutes. Avoid rubbing, which can scratch the cornea and cause conjunctivitis. Seek medical attention if redness persists or there are signs of infection. To prevent chili burns, wear gloves when handling chilies, wash hands thoroughly afterward, and avoid touching your eyes or nose.
