Kiwi company Goodair has developed a drug-free solution to fighting nasal congestion.

Nosebuds promise to enhance diaphragmatic nasal breathing in order to reduce the impact of pressure and drainage while providing pain relief.

Inventor and designer Dr David White says the buds emit a humming sound that applies mechanical stress to the affected area.

"A third of the population suffers from nasal congestion, either through allergy or infection. That's commonly treated through pharmaceuticals- which all have negative side effects."
