This external application, often called a “plaster” or “poultice,” uses the thermogenic properties of mustard and ginger to draw heat to the lower extremities. By stimulating the nerve endings in the feet, this action encourages systemic circulation and is traditionally used to help “pull” congestion down from the chest and head.

The Benefits

• Reflexive Stimulation: The soles of the feet are highly sensitive. The mild heat from the mustard powder triggers a reflexive response in the circulatory system, encouraging blood to move away from a congested core and toward the surface of the skin.
• Warming Action: Ginger and mustard are both rubefacients, meaning they cause a mild reddening of the skin as capillaries dilate. This localized warmth is particularly soothing for those feeling a deep, internal chill.
• Respiratory Support: Through the principle of counter-irritation, increasing circulation in the feet can help ease the pressure of a heavy head cold or a stagnant, productive cough.

Warming Foot Plaster

This process involves a specific “action” of application. Because mustard can be quite potent, it is essential to follow the barrier method described below to protect the skin.

Ingredients

• 2 tablespoons dry mustard powder
• 1 tablespoon ginger powder (or freshly grated ginger)
• 1/2 cup flour (acts as a binder and buffers the heat)
• Warm water (enough to form a thick paste)
• Olive oil or coconut oil (for the skin barrier)
• Two pieces of thin cotton cloth or old muslin
• Thick wool socks

Instructions

1. In a small bowl, mix the mustard powder, ginger, and flour together.
2. Slowly stir in warm water, one tablespoon at a time, until you achieve the consistency of a thick, spreadable paste.
3. The Action: Apply a generous layer of olive oil or coconut oil directly to the soles of your feet. This creates a vital protective barrier between your skin and the active mustard.
4. Spread the paste onto the center of your cotton cloths, then fold the cloth over to encase the paste (like a flat burrito). Never apply the mustard paste directly to the bare skin.
5. Press the cloth “plaster” against the soles of your oiled feet.
6. Pull the thick wool socks over your feet to hold the plasters in place.
7. Rest with your feet slightly elevated for 10 to 20 minutes.
8. Safety Note: Check the skin every few minutes. A warm, tingling sensation is normal, but if the area feels uncomfortably hot or starts to sting, remove the plaster and wash the area immediately with cool water.
9. After removing, wipe the feet clean and keep them wrapped in dry socks to maintain the warmth.
