Sourcing & Purity Guide

Gas Chromatography/Mass Spectrometry (GC/MS) testing is the gold standard for verifying the purity and composition of essential oils. These reports provide a detailed chemical breakdown of an oil, revealing its exact constituents and their percentages.

When reviewing a GC/MS report, look for the presence of expected compounds that are characteristic of the specific oil. For example, true lavender oil should contain significant amounts of linalool and linalyl acetate. The absence of these key compounds or the presence of unexpected synthetic chemicals may indicate adulteration.

Reputable suppliers make GC/MS reports readily available for their products. If a supplier cannot or will not provide these reports, it's a red flag that the oil may not be pure or authentic.

Ethical sourcing goes beyond quality—it encompasses how plants are grown, harvested, and processed, as well as how workers and communities are treated throughout the supply chain.

Look for suppliers who practice sustainable farming methods, support fair trade initiatives, and work directly with growers. This ensures that the communities producing these oils receive fair compensation and that farming practices protect the environment for future generations.

Many ethical suppliers are transparent about their sourcing locations and can provide information about their relationships with growers. They often participate in certification programs that verify their commitment to sustainable and ethical practices.
