Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Andrographis paniculata has a long history of use in traditional medicine, especially in Ayurveda and Traditional Chinese Medicine, for the treatment of infectious and febrile illnesses. More recently, scientific studies have explored its efficacy in supporting the body against contagious diseases, particularly respiratory tract infections such as the common cold and influenza. Meta-analyses and systematic reviews of randomized controlled trials indicate that standardized Andrographis extracts can reduce the severity and duration of symptoms in acute upper respiratory tract infections, with some evidence suggesting it may decrease the likelihood of developing complications. Its presumed mechanisms of action include immunomodulatory, anti-inflammatory, and antiviral effects, largely attributed to its main active constituent, andrographolide. However, while these findings are promising, most studies focus on mild to moderate viral respiratory illnesses; robust evidence for its use in other contagious diseases (such as bacterial or more severe viral infections) is limited. Overall, the evidence base is moderate, warranting a rating of 3, and suggests Andrographis may be a helpful adjunct for mild contagious respiratory diseases, but more research is needed to define its role in other infectious conditions.
