bubble_chart Preparation and Dosage

Place the above ingredients in a bowl, cover tightly with another bowl, and seal with paper. Roast over a small piece of charcoal about the size of an egg for approximately half an hour. Allow to cool before opening. A small amount of white frost will form on the upper bowl. Place this frost on the affected tooth for immediate relief. Avoid excessive heat, as it will turn the frost red; the white frost is preferable.
