“…In a double-blind, parallel-group, randomised (simple randomisation), pilot study, Chisan ® (ADAPT-232; Swedish Herbal Institute, Askloster, Sweden), a standardised fixed combination of extracts of Rhodiola rosea, Schisandra chinensis and Eleutherococcus senticosus, was evaluated for its efficacy as an adjuvant therapy for the improvement of the quality-of-life and recovery period of patients suffering from acute non-specific pneumonia and receiving a standard treatment (Narimanian et al, 2005). Sixty patients (males and females; 18-65 years old) received a standard treatment with cephazoline, bromhexine, and theophylline: in addition, one group of 30 patients received Chisan mixture whilst the second group of 30 patients received a placebo, each medication being taken twice daily from the beginning of the study for 10-15 days.…”
