A DOUBLE-BLIND-STUDY WITH A NEW MONODRUG KAN-JANG - DECREASE OF SYMPTOMS AND IMPROVEMENT IN THE RECOVERY FROM COMMON COLDS

In a placebo-controlled double-blind study, the therapeutic effect of Kan Jang tablets made from Andrographis paniculata (Barm. F.) (Ness) d ried extract was tested in patients with common colds. The patients we re divided in two groups, in which group 1 (n=33) received 1200 mg of Andrographis paniculata and group 2 (n=28) a placebo (P). On day 3-4 a fter treatment the possible effect of Kan Jang tablets on selected sym ptoms and clinical signs of common cold was evaluated. A significant r eduction in clinical symptoms at day 4 of administration of the Kan Ja ng tablets was observed. A better efficacy against the placebo is disc ussed. The differences in the total 'sumscores' of clinical and sympto matic findings indicate that the Kan Jang treated group did far better than the placebo group. We conclude that Kan Jang in a dose of 1200 m g daily has the capacity to significantly shorten the course/duration of the disease and therefore is indicated for an enhanced resistance t o common cords.
