Benzoin Styrax (tonkinese) is a soft, sweet calming vanilla-like scent that blends well with other essential oils. It extends the vanilla scent without overwhelming the blend. The aroma is calming, sensual and rejuvenating. Benzoin combines well with any essential oil . I like to add it to Oriental and masculine aroma blends such as, Patchouli,Tarragon, Vetiver and Labdanum. It blends with florals and herbals in small quantities.
