Stuffy nose? These nasal sprays convince Stiftung Warentest
Due to the 30 products tested, the product testers recommend the 15 isotonic nasal sprays, which contain only water and salt. Isotonic nasal sprays help moisten and clean the nasal lining, which is good for cold or dry hot air.
In addition to isotonics, there are also hypertonic nasal sprays which use an increased concentration of salt to ensure that water is drawn from the surrounding cells. This should have a decongestant effect on a runny nose. However, product testers are less than convinced of this type of nasal spray: the effect is minimal and does not last long. Hypertonic nasal sprays can also cause a burning sensation in the nose.
Whether isotonic or hypertonic: many manufacturers add additives such as dexpanthenol, aloe vera, chamomile flower extract or essential oils to their nasal sprays or drops. You also need to take care of your nose. According to product testers, however, this effect has not been sufficiently proven.
Stiftung Warentest even advises against products with essential oils such as peppermint or eucalyptus. They can cause allergic reactions in sensitive people.
