“…The existing double-blind, randomized, controlled trials on efficacy and safety of EPs 7630 in acute, viral respiratory disorders were summarized and evaluated in several reviews and meta-analyses (Matthys et al, 2013;Matthys et al, 2016;Schapowal et al, 2019;Seifert et al, 2019;Seifert et al, 2021;Kardos et al, 2022;Matthys et al, 2023). Compared to placebo, the authors consistently observed significant advantages of EPs 7630 for the efficacy outcomes assessed, i.e., the primary outcomes as assessed by disease-specific symptom scores (Matthys et al, 2016;Schapowal et al, 2019;Kardos et al, 2022) and the secondary outcomes time to substantial improvement or complete remission (Matthys et al, 2016;Schapowal et al, 2019;Seifert et al, 2019), disease-associated quality of life (QoL; Kardos et al, 2022), concomitant use of paracetamol (Matthys et al, 2016;Seifert et al, 2019;Seifert et al, 2021), and days missed at work or school (Schapowal et al, 2019;Seifert et al, 2019;Seifert et al, 2021;Matthys et al, 2023). Moreover, a systematic review and network meta-analysis demonstrated that P. sidoides extract is effective in improving the symptoms of the common cold and of acute post-viral rhinosinusitis with moderate certainty of evidence (Hoang et al, 2023).…”
