Instructions

  • Mix the mustard powder and flour together in a bowl.
  • Slowly add the warm water to form a thick paste.
  • Spread the paste onto a piece of cloth or gauze (a thin towel or handkerchief can work well).
  • Apply the cloth to the skin, ensuring it’s in contact with the affected area (e.g., chest, back, or sore muscles).
  • Leave it on for about 10-15 minutes, or until you feel a warming sensation. It should not cause extreme discomfort—if it does, remove it immediately.

Aftercare:

  • Once you remove the plaster, wash the skin with warm water to remove any leftover mustard paste. It’s important to moisturize afterward, as the skin might feel dry or irritated.
