Steam. Steam is also an effective remedy to help ease a dry cough. The moisture in steam can help to relieve dryness and irritation in the throat. It can also help to loosen and thin mucus that may be present, aiding the body in removing it. Easy ways to use steam include breathing in steam from a hot shower or using a humidifier. Another way is to fill a bowl with hot water, lean over the bowl with a towel over the head and breathe in the steam. Essential oils, such as eucalyptus or rosemary, can be added to the hot water for additional decongestant benefits.
