* 1 part Elecampane
* 1/2 part Coltsfoot
* 1 part Mullein leaf
* 1/2 part Usnea
* 1 part Marshmallow
* 1/4 part Osha
* 1/2 part Echinacea

Preparation: Choose a part and combine the required proportions of the herbs together and mix well. This formula is best prepared as a tincture (see Herbal Preparation Methods) but can be prepared as a tea as well. You may want to increase your dosage of Usnea in addition to the amount provided in this formula, especially if you are preparing the Bronchial Formula as a tea because the usnic acid does not dissolve well in water.

Dosage is 30 drops 3 times per day, or up to 4 cups of tea per day using 1 tablespoon of herb per cup.
