Costus oil

Whatsapp Order

Costus Oil is a rare essential oil derived from the steam-distilled roots of Saussurea costus (also known as Saussurea lappa), a Himalayan herb long valued in traditional systems such as Ayurveda, Unani, and Chinese medicine. The oil has a deep amber to brown color and a rich, earthy, woody, and musky aroma. It is well-known in perfumery as a natural fixative and is widely used in spiritual rituals, incense making, high-end fragrances, and therapeutic blends.

Due to its grounding scent and potential anti-inflammatory, antimicrobial, and calming properties, Costus Oil is incorporated into personal care, topical formulations, and aromatherapy. It is a powerful aromatic oil that must be used in moderation and diluted due to its strong sensitizing compounds.
