Andrographis paniculata, sometimes called "Indian echinacea," is a bitter herb with a long history in traditional Asian medicine that has attracted modern scientific interest for its potential role in respiratory and immune health. Research suggests that standardized extracts, particularly the Kan Jang and SHA-10 preparations, may help reduce the severity and duration of upper respiratory tract infections, including the common cold, especially when taken early in the course of symptoms. Studies indicate that the herb's active compounds, known as andrographolides, appear to support immune function and may contribute to the management of fever and inflammation associated with acute respiratory illness. While findings are promising, researchers note that larger, high-quality trials are still needed to fully clarify its benefits across diverse populations.
