👶 Safe for children?
This remedy carries age-related cautions. Please read them before giving it to a child, and check with your pediatrician or pharmacist first.
- Avoid on infants under 12 months. For older children use only the weakest mixture (1:8 or milder) with constant supervision — mustard can blister tender skin quickly.
🥄 How to use it
Mix 1 tablespoon dry mustard with 4 tablespoons flour for an adult (8 or more tablespoons of flour for a child; not for infants under 12 months) and enough tepid water to make a spreadable paste. Spread it on a cloth, leave a wide margin, and place it on the skin with one thin cloth layer between paste and skin. Cover with plastic and a towel. Leave on up to 20 minutes — remove sooner if the skin is well reddened or stings. Wipe all traces off with oil on a tissue, then cover the warm, pink area with flannel.
How much: Up to 20 minutes, once daily at most; remove at strong redness or any burning.

Mustard's warming compounds draw blood strongly to the skin. This counterirritant effect is the traditional rationale for relieving deep chest congestion, stubborn coughs, and muscular back pain, always in short, carefully watched applications.
Ways to prepare it
⚠️ Cautions
- Mustard can blister — never leave it on past clear reddening or through numb skin, and never let the paste touch the skin directly.
- Avoid on infants under 12 months. For older children use only the weakest mixture (1:8 or milder) with constant supervision — mustard can blister tender skin quickly.
- Do not fall asleep with a plaster in place.
- Stop immediately if stinging or burning is more than mild.
- Not for people with reduced skin sensation, such as with diabetes or neuropathy.
