Phellochin is primarily used in the field of natural product research and pharmaceutical development due to its bioactive properties. It exhibits strong antioxidant activity, making it valuable in formulations aimed at reducing oxidative stress. Its polyphenolic structure contributes to anti-inflammatory effects, which are explored in the context of chronic disease prevention. Studies suggest potential in dermatological applications, where it helps protect skin cells from environmental damage and supports anti-aging treatments. Additionally, Phellochin has shown inhibitory effects on certain enzymes involved in metabolic disorders, indicating possible use in managing conditions like diabetes. Ongoing research also investigates its role in enhancing the stability and efficacy of natural extracts in functional foods and nutraceuticals.
