Patchouli alcohol is widely used in the fragrance industry due to its earthy, woody, and slightly sweet aroma. It serves as a key ingredient in perfumes, incense, and essential oil blends, valued for its long-lasting scent and fixative properties that help stabilize volatile components.

In traditional medicine, it is recognized for its anti-inflammatory, antimicrobial, and calming effects. It is commonly incorporated into aromatherapy products to help reduce stress and anxiety. Some studies suggest potential neuroprotective and anti-allergic benefits, leading to interest in its use for therapeutic formulations.

Patchouli alcohol is also used in cosmetics and skincare products for its soothing properties and natural origin. Additionally, it acts as a natural insect repellent in certain eco-friendly pest control solutions.
