The effects of Zataria multiflora on clinical symptoms, pulmonary function tests, oxidative stress, and C-reactive protein levels in chronic obstructive pulmonary disease (COPD) patients were evaluated. Forty-five patients were allocated to 3 groups: placebo group and 2 groups that received 3 and 6 mg/kg/day Z. multiflora extract (Z3 and Z6) for 2 months. Clinical symptoms, pulmonary function tests, oxidative stress, and serum C-reactive protein levels were evaluated pretreatment (step 0) and 1 (step I) and 2 (step II) months after treatment. Clinical symptoms including breathlessness and chest wheeze in Z3- and Z6-treated groups and sputum production only in the Z6-treated group were significantly improved 1 and 2 months after treatment compared with baseline values (P < .01 to P < .001). The FEVwas significantly increased after 2 months of treatment with Z3 and Z6 (P < .05 to P < .01). Malondialdehyde and nitrite levels were significantly decreased after a 2-month treatment with Z6 compared with step 0 (P < .05 to P < .01). The thiol contents in the Z6 group as well as superoxide dismutase and catalase activities in both groups treated with the extract were significantly increased in step II compared with step 0 (P < .05 to P < .01). The C-reactive protein level at the end of the study was significantly reduced compared with the step 0 in both treated groups (P < .05 for both cases). Two-month treatment with Z. multiflora improved clinical symptoms, pulmonary function tests, oxidative stress, and C-reactive protein in COPD patients. The results suggest that this herbal medicine could be of therapeutic value as a preventive drug for the treatment of COPD.
