A Vaporizer heats the oil, thereby releasing moisture and steam into the air. Any liquid (essential oil) added to this device will change into a vapor or gas and be released into the air with the steam. Purpose: Increase moisture for inhalation by heating oils.
Herbal steams are used to deliver the medicinal qualities of herbs and essential oils directly to the respiratory tract. They hydrate, warm and decongest the mucus membranes of the nose, sinuses, and throat. They can be used to help fight infection in these area and the lungs, and are helpful in calming cough.
The most common cause of sinus and lung congestion is a cold or flu virus. Additionally, secondary bacterial infections that follow on the heels of colds and flus can be especially nasty, irritating the delicate lining in the respiratory tract. The mucus that causes the congestion is produced to protect that lining and wash away the infection.
For quick relief, thin out congestion by using the essential oils of eucalyptus, peppermint, and bergamot combined with steam. Remember how much easier it is to breathe when you step into a steamy, hot shower? The steam opens up tightened bronchial passages, allowing the essential oils to penetrate and wipe out the viral or bacterial infection that is causing the problem.
Two of the best essential oils to eliminate infection are lavender and eucalyptus. In fact, studies prove that a two-percent dilution of eucalyptus oil kills 70 percent of airborne staphylococcus bacteria. Anise, peppermint, and eucalyptus reduce coughing, perhaps by suppressing the brain's cough reflex. If congestion is severe, also use essential oils that loosen congestion, such as those listed below. Cypress dries a persistently runny nose.
