Andrographis for the relief of acute respiratory infections

In this study, Andrographis Paniculata was examined for its uses in cough, cold, and influenza (1). The authors suggest it should be helpful in respiratory tract infections (RTIs). They performed a systematic review to evaluate its clinical effectiveness. They searched numerous medical databases and the primary outcomes were improvement in ARTI symptoms and adverse events. They performed statistical analyses. The results showed that 33 randomized controlled trials were included. Most examined Andrographis as a monotherapy or as a herbal mixture. It was shown to improve cough and sore throat when compared to placebo. The authors conclude that it had statistically significant effect in improving overall symptoms of ARTIs when compared to placebo, usual care, and other herbal therapies.
