Natural treatments for hoarseness include breathing in moist air with a humidifier or steam from a hot shower, resting the voice and moistening the throat by sucking on lozenges, chewing gum or gargling with salt water, according to Mayo Clinic. People with hoarseness should avoid whispering and talking loudly.
Moisture in the air produced by a vaporizer or humidifier helps to soothe swollen air passages, explains WebMD. Fluids also soothe an irritated throat and help to thin secretions that could be contributing to hoarseness. Patients should avoid the use of tobacco or exposure to smoke to avoid worsening a hoarse voice.
