The essential oil of the rootlets of Cyperius scariosus (or cyperus scariosus) is marketed under the brand name of Cypriol in India. The oil has been known for many decades in its home country where the roots are used in the same way as vetiver roots for the scenting of sari’s and other women’s clothing. The grass is locally known as Nagar Mustaka.
Nagarmotha oil is produced by steam distillation of roots and rhizomes after proper washing, drying and comminuting, similar to the treatment of vetiver rootlets.
Oil of Cyperus Scariosus (“Nagarmotha”) is an amber colored or light brown viscous liquid of woody-earthy and very tenacious odor. The very first impression of the odor of this oil bears great resemblance to the odor-impression of the “Oriental” cinnamon-olibanum complex: diffusive, dry, woody, slightly spicy .The overall bodynote resembles that of Virginia cedarwood and vetiver oils, but toward the dryout there is a strong similarity to vetiver in sweet-woody and rich undertones. Apart from the excitingly fresh topnote this oil is distinguished by a firm uniformity in odor throughout all stages of evaporation.
Nagarmotha blends well with bergamot, Iabdanum, patchouli, sage clary, etc. for dry ambre notes which can be further enhanced by the addition of very small amounts of c<fixateur 404” or the complex “grisambrol”, etc. Cypriol is useful in perfumes or bases of the woody, Oriental or dry-ambre types, in heavy fougeres, in hyacinth (along with galbanum resinoid), in forest notes and in general as a fixative. In higher concentrations it will display its peculiar, soft-woody note and intriguing topnotes. The relatively low cost of this oil makes it attractive even in soap perfumery where its odor-tenacity and stability come to their right.
