andrographis
Andrographis paniculata, also known as 'King of Bitters,' is a medicinal plant traditionally used in Ayurvedic and Chinese medicine. Its primary active compound, andrographolide, demonstrates antiviral, anti-inflammatory, and immune-modulating properties by interfering with viral replication pathways and regulating inflammatory cytokines. It is primarily used for respiratory infections, immune support, and inflammatory conditions.
