Cleanse the body and mind and reduce nasal irritation often experienced in pregnancy with the Breathe Candle From Help Your Pregnancy. Non-allergenic rhinitis can often be caused by the changes in hormones during pregnancy and although a blocked nose may not be the most common symptom experienced, for those that it affects, it can be one of the most frustrating. The HYP Breathe candle is blended with eucalyptus, tea tree and lavender oils which work together to provide a gentle yet effective decongestant.
