The benefits provided by Echinacea Purpurea combined with vitamin C, zinc and selenium are especially important for older people, for whom an upper respiratory infection can lead to a serious lung condition – chronic obstructive pulmonary disease (COPD).
COPD is the 4th most widespread cause of death in the world for people over 45, and it is the only disease for which mortality is increasing. It is forecasted that by 2020, incidence of COPD will rank 5th, surpassing all other respiratory diseases. Using Echinacea in combination with vitamin C, zinc and selenium (rather than pure extract of Echinacea Purpurea) significantly alleviated exacerbations of COPD following upper respiratory infections1. The study involved 108 male subjects aged 40-81 (average age – 65.8). In order to assess effectiveness, the supplement was taken for 14 days, and at the same time the subjects also continued to take the traditional ciprofloxacin for 7 days. No interaction between the two substances was observed.
