Andrographis paniculata is a medicinal herb widely used in traditional Asian medicine, especially in Ayurveda and Traditional Chinese Medicine, for treating infections and fever. In recent decades, scientific studies have investigated its potential as an alternative or adjunct to antibiotics, primarily due to its purported antimicrobial, antiviral, and anti-inflammatory properties. Several in vitro and animal studies have demonstrated that extracts and key compounds from Andrographis paniculata (notably andrographolide) can inhibit the growth of certain bacteria, including Staphylococcus aureus and Escherichia coli, and modulate immune responses. However, robust clinical trials in humans are limited, and most available research focuses on upper respiratory tract infections, where Andrographis may help reduce symptom severity and duration, rather than directly replace antibiotics for bacterial infections.

Meta-analyses and systematic reviews (including Cochrane reviews) have found that Andrographis paniculata is effective for treating uncomplicated respiratory tract infections, with a safety profile comparable to placebo. However, evidence for its use as a true antibiotic alternative—meaning a replacement for antibiotics in treating confirmed bacterial infections—is still preliminary. Most clinical trials do not confirm bacterial etiology or compare efficacy directly to antibiotics but rather to placebo or symptomatic care.

In summary, while there is a scientific basis for its use in supporting immune response and potentially reducing mild infection symptoms, Andrographis paniculata cannot currently be considered a direct substitute for antibiotics in established bacterial infections, and further research is needed to clarify its role.
