Coughs, colds, hayfever and asthma are common respiratory health conditions. Here at Health and Vitality we have a number of products to support respiratory health. Salt lamps are great for people suffering with asthma and hayfever. Salt inhalers can improve overall respiratory function. Supplements such as NAC and herbs like Ivy and Thyme can open up the lungs, as well as essential oils like eucalyptus and peppermint.
