Prof. Benjamin Murphy, Ph.D.Selecting high-quality essential oils requires being aware of key signs of purity. The complete botanical name is required on the label, like Lavandula angustifolia for true lavender. You should demand GC/MS test reports verifying the chemical composition. Choose companies that are certified organic by the USDA or ECOCERT. I refuse to use oils that do not have this information.
Label Inspection
- Check for complete botanical names (genus and species)
- Verify country of origin information
- Look for extraction method details
- Confirm batch numbers and expiration dates
Physical Tests
- Paper test: Pure oils evaporate without greasy residue
- Aroma check: Authentic scents evolve over time
- Viscosity test: Consistency should match oil type
- Color examination: Natural variations indicate purity
Documentation Review
- Request GC/MS reports from suppliers
- Check third-party organic certifications
- Review material safety data sheets
- Verify fair trade or sustainability certifications
Try the simple home tests beforehand. The paper test indicates which oils contain additives, as it reveals whether they leave a residue, suggesting that they likely have additives. The pure oil evaporates entirely and cleanly. Take the oil and, over several hours, notice the evolution of the oil's smell. To indicate when oils are contaminated, they will appear milky or cloudy. I try every new oil using these methods.
Consider packaging and storage as markers of quality. Quality oils are stored in dark cobalt or amber glass bottles. This signifies a much higher standard than plastic bottles. Look for tampering on evident seals. Do not buy oils that are stored in warm or lighted places. My supplier uses UV-protected packaging.
Understand why quality is important for therapeutic results. Pure oils function in therapeutic aromatherapy purposes without inferior performance. Adulterated oils can lead to skin eruptions and reduced effectiveness. A dollar spent for quality is a safe and sure dollar hard at work. The writer spends money on oils that are carefully tested.
