Aura Cacia Lavender Essential Oil

• Aura Cacia posts a GC/MS summary for this oil (item 191123), signed by its analytical lab manager. It lists linalool 30.60%, linalyl acetate 30.54%, 1,8-cineole 1.38%, camphor 0.24% and a refractive index of 1.4612, and says no contamination or adulteration was detected.
• Its quality page says every shipment is tested in its own labs in Iowa and every batch is gas chromatography tested. It also says the benefits of essential oils do not require swallowing them.
• The caution is plain: “Not for internal use.” It adds: dilute properly, avoid eyes and mucous membranes, keep out of reach of children, consult a practitioner if pregnant, nursing or on medication, and the product is flammable.
• At $12.88 for 15 mL (about $0.86 a mL) it is the cheapest per milliliter among the 10 to 15 mL bottles we list, and iHerb listed it at $9.30 (about $0.62 a mL).

• The summary is for “this Lavender, Bulgaria batch sample”. It shows no lot number or date, so it cannot be matched to your bottle, and the lab is the company’s own. We treat it as the maker’s claim.
• The page says lavender is “one of the safest essential oils for both adults and children, with research supporting its many benefits”. That goes beyond what our lavender article finds, and it gives no dilution figure for children.
• The page says the flowers are collected and distilled but not by what method; the test summary says steam distillation of the flowering tops. Neither says what the bottle and cap are made of, though the product photo shows an amber glass bottle with a white screw cap.
• The front label on this bottle says “relaxing”, a benefit claim of its own.
