Bisandrographolide C is primarily studied for its potential anti-inflammatory and immunomodulatory effects. It has shown promise in reducing inflammatory markers in preclinical models, particularly by inhibiting signaling pathways involved in the production of pro-inflammatory cytokines such as TNF-α and IL-6. This suggests possible use in managing chronic inflammatory conditions like arthritis and type 2 diabetes, helping to reduce tissue damage from chronic inflammation.

Research also indicates antiviral activity, particularly against certain respiratory viruses, making it a candidate for development in antiviral therapies.

Additionally, it exhibits hepatoprotective properties, helping protect liver cells from damage caused by toxins or disease, such as alcohol or certain drugs. Studies show it enhances intracellular antioxidant systems, including increased activity of superoxide dismutase (SOD) and glutathione peroxidase (GPx).

In drug development, it is considered a lead compound for designing new drugs with more specific effects, especially in diseases related to inflammation and oxidative stress. Its role in traditional herbal formulations supports its use in supporting immune health, though clinical applications remain under investigation.
