Andrographolide, the primary bioactive compound in Andrographis paniculata (commonly known as "King of Bitters"), is renowned for its multifaceted therapeutic properties. Modern scientific studies validate that over 70% of the plant’s health benefits stem from andrographolide, which constitutes 10%-30% of the extract’s total diterpene lactone content. This potent compound exhibits anti-inflammatory and immunomodulatory activities 20-50 times stronger than common herbal alternatives like echinacea. Derived through advanced extraction techniques, andrographolide is a water-soluble, highly stable molecule with a unique bicyclic diterpenoid structure. Its mechanism of action includes modulating NF-κB signaling pathways, making it a critical agent in combating chronic inflammation, viral infections, and immune dysregulation. Furthermore, its hepatoprotective properties and ability to enhance detoxification enzymes position it as a cornerstone in modern herbal pharmacology.
