When we usually cut peppers, our hands will burn like fire, which is very painful. No matter how we wash them, we can't wash them off. We can only temporarily relieve them and burn them after a while. The hottest pepper is capsaicin, called capsaicin. When cutting peppers, capsaicin will stick to the skin, causing microvascular dilation, causing skin redness and fever, and stimulating painful nerves. That's why we usually feel our hands burning. It can be scrubbed repeatedly with medical alcohol or white wine. Capsaicin in pepper can be dissolved in alcohol and alkaline aqueous solution, and alcohol can dissolve capsaicin in hand.

Wipe your hands with white vinegar. Capsaicin is alkaline, and vinegar can neutralize capsaicin, but the acetic acid content in vinegar is limited, so the effect is limited, which can be slightly alleviated. Brush your teeth with toothpaste. Most toothpastes are alkaline, which can dissolve capsaicin in your hands. It contains a coolant, which can achieve the effect of cold compress and inhibit the burning sensation, but once washed off, it will cause burning sensation. This is only a temporary solution, not a permanent treatment.

Wipe your hands with cool oil. Cool oil can cool and dissipate heat. You can try to use cool oil to relieve the feeling of hot hands. Use fluoxetine cream or ointment with similar functions: fluoxetine cream is used to relieve and treat dermatitis, which is effective in treating skin redness and pain, so proper application can also relieve it. Apply cooking oil to your hands. Capsaicin is fat-soluble and can also dissolve capsaicin in your hands. This is the most effective method mentioned above.

The effective components of household vinegar and alcohol are limited and difficult to remove. Toothpaste, cooling oil and ointment can relieve burning pain, but they can only cure the symptoms, not the root cause. Hot water will aggravate the burning and tingling sensation, and will not help to remove capsaicin. Cooling with cold water can only temporarily relieve the burning sensation of fingers. The root of pepper is capsaicin, which is insoluble in water and oil, so you can choose to remove it with oil.
