Decursinol is widely used in the pharmaceutical and nutraceutical industries due to its bioactive properties. It is primarily recognized for its neuroprotective effects, making it a valuable component in treatments aimed at preventing or mitigating neurodegenerative diseases such as Alzheimer's and Parkinson's. Additionally, its anti-inflammatory and antioxidant properties contribute to its use in formulations designed to reduce oxidative stress and inflammation in various tissues. Decursinol is also explored for its potential in enhancing cognitive function and memory, which has led to its inclusion in supplements targeting brain health. Furthermore, its role in promoting skin health by protecting against UV-induced damage and improving skin elasticity has made it a popular ingredient in cosmetic products. Research continues to uncover its potential in cancer therapy, particularly in inhibiting the growth of certain cancer cells and enhancing the efficacy of conventional treatments.
