The stimulation of circulation will aid chilblains as well as the conditions already mentioned. An infusion or poultice of Mustard will aid in cases of bronchitis.
Preparations & Dosage: Poultice: Mustard is most commonly used as a poultice which can be made by mixing l00 grams (4 ounces) of freshly ground mustard seeds with warm water (at about 45 degrees C) to form a thick paste. This is spread on a piece of cloth the size of the body area that is to be covered. To stop the paste sticking to the skin, lay a dampened gauze on the skin. Apply the cloth and remove after l minute. The skin may be reddened by this treatment which can be eased by applying olive oil afterward. Infusion: pour a cup of boiling water onto l teaspoonful of mustard flour and leave to infuse for 5 minutes. This may be drunk three times a day. Foot bath: make an infusion using l tablespoon of bruised seeds to l litre (2 pints) of boiling water.
