Phytomedicine. 1997 Feb;3(4):315-8. doi: 10.1016/S0944-7113(97)80002-5.


Kanjang(®) tablets (standardized Andrographis paniculata extract) have proven effective in the initial treatment of commond cold and sinusitis. Kanjang(®) tablets is a herbal formula, which has been developed by the Swedish Herbal Institute in Gothenburg. The tablets have shown a beneficial effect with regards to the subjective experience of initial symptoms of common cold and uncomplicated sinusitis, as well as to the duration of the symptoms. The preparation has been used in the Nordic countries for more than 12 years, mainly for reducing symptoms of common cold and sinusitis, and shortening the duration of the symptoms. In this controlled, double-blind study performed as a pilot trial at the Health Center, Hallehälsan, during the autumn of 1992, conducted in 50 patients, both subjective symptoms as well as duration of the symptoms were significantly reduced. From the results evaluated it is quite clear that Kanjang(®) tablets decrease the subjective symptoms of common cold as well as shortening of the period of sick leave significantly.
