A method of providing halotherapy to the upper portion of the lower respiratory tract includes the steps of operating a dispenser and inhaling. The dispenser contains a dry sodium chloride powder. The user operates the dispenser to release a dosage of the powder for inhalation when the dispenser is aimed into the user's mouth. The user then inhales the dosage of powder through the mouth. Because the powder has a particle size range enabling the powder to target the upper portion of the lower respiratory tract without entering the user's lungs, the dosage of the dry powder provides a concentration at the upper portion sufficient to provide effective halotherapy. The preferred particle size range is from about 5 microns to about 20 microns. The preferred dosage is about 3 milligrams of powder.
