Zilara uses the term therapeutic grade to describe essential oils that meet our standards for purity, composition, sourcing, and intended aromatic use.
There is no official government or industry-wide grading system that certifies an essential oil as “therapeutic grade.” Instead, essential oil quality is evaluated through factors such as botanical identity, sourcing, distillation practices, purity, and chemical composition.
Zilara essential oils are independently tested using Gas Chromatography (GC) to evaluate their chemical profiles. Each batch is reviewed against our quality standards before it is approved for bottling and sale.
Every essential oil bottle also carries lot and batch information that supports product traceability.
