Pinosylvin is primarily known for its natural fungicidal properties, making it valuable in protecting wood against decay and fungal invasion. It is used in eco-friendly wood preservatives, especially in applications where minimizing chemical toxicity is important. Due to its antioxidant and antimicrobial activities, pinosylvin is also explored in the development of natural preservatives for cosmetics and topical formulations. Its ability to inhibit microbial growth supports its use in sustainable packaging and coatings. Additionally, research is ongoing into its anti-inflammatory and potential anticancer effects, suggesting future applications in pharmaceuticals and health supplements.
