Caulophyllum is a clinical herb of the Asteraceae family, with the effect of clearing heat, dispelling dampness and opening the nasal passages, a herb necessary for the treatment of rhinitis and a component of many proprietary Chinese medicines. It is certain and possible to treat rhinitis with Caulophyllum aromaticum oil, but we need to know the composition and concentration of Caulophyllum aromaticum oil to blend, how clean it is, and whether using it into the nasal cavity will cause secondary infections, all of which are problems that exist. The modern pharmaceutical industry is very advanced and many drugs for rhinitis are gradually being developed and are more effective than conventional drugs. Therefore, although Caulophyllum fragrans oil can treat rhinitis, it is at most an adjunctive treatment and cannot be used as the main clinical medicine or the main method of treatment.
