Praeroside II is primarily studied for its potential anti-inflammatory and immunomodulatory effects. It has shown activity in reducing pro-inflammatory cytokines, making it a candidate for research in inflammatory diseases such as arthritis and asthma. It may also support liver protection by reducing oxidative stress and improving liver enzyme levels in preclinical models. Due to its natural origin and bioactive properties, Praeroside II is explored as a lead compound in developing herbal-based therapeutics, particularly in traditional medicine formulations targeting metabolic and immune-related disorders. Its application remains mostly in the early research phase, focusing on pharmacological screening and mechanism validation.
