Anti-inflammatory effects of asiaticoside on tumor necrosis factor-α and interferon-ᵧ Induced raw 264.7 macrophage

Centella asiatica is one of the most commonly used medicinal herbs in traditional medicine. Its beneficial effects have been attributed to its major isolated triterpene, Asiaticoside. It has been described to exhibit anti-inflammatory activities in several models. Inflammatory cells produce large am...
