Saikosaponin A is widely studied for its anti-inflammatory and immunomodulatory properties. It has shown potential in supporting liver health by protecting against liver damage and promoting liver function, making it relevant in formulations targeting hepatitis and other liver disorders. It also exhibits antiviral activity, particularly against viruses such as hepatitis B and influenza, which contributes to its use in traditional and modern antiviral therapies. In cancer research, Saikosaponin A demonstrates anti-proliferative effects on various tumor cell lines by inducing apoptosis and inhibiting cell cycle progression. It has been investigated for its role in enhancing the efficacy of chemotherapy drugs while reducing their side effects. Additionally, it shows neuroprotective effects and is being explored for applications in neurodegenerative conditions like Alzheimer’s disease due to its ability to reduce neuroinflammation and oxidative stress. Its ability to modulate immune responses also makes it useful in managing autoimmune diseases and allergic reactions. Due to these diverse biological activities, Saikosaponin A is used in herbal medicine formulations, dietary supplements, and as a lead compound in drug development.
