A few of the major treatments are zinc compounds, vitamin C, and echinacea products. Although there are a few publications on these compounds, many clinicians consider the results inconclusive. Others recommend if the compounds are not used to excessive, they might be helpful. Studies in 2012 suggested zinc may decrease symptoms by about one or two days but may create a metallic flavor or cause hearing problems. Some doctors suggest that the side results are not worth the main one to two times of decreased or absent symptoms.

To measure lung dosage the experts sampled a lower airway cell called the airway macrophage – a specialised cell that sits on the airway surface and ingests foreign materials. The researchers gathered sputum samples from five adults who regularly cycled to work in London and five pedestrians and analysed the quantity of black carbon within their airway macrophages.
