Patchouli essential oil has a rich, earthy scent that is popular in the perfume industry as a base note. The herb, a perennial with fragrant leaves and pink tubular flowers, has been used historically to scent linens and repel moths in Southern Asia. In the USA, Patchouli and Sandalwood became the fragrance of the hippie cultural revolution in the 1960’s. Patchouli’s grounding personality is helpful for promoting balanced emotions and relaxation.
