How we evaluated it
Why we chose it What put it on our list
- Reports are posted for three lots: L40122R (Bulgaria, July 2025), L40123R (Bulgaria, November 2025) and L40124R (Greece, February 2026). We opened all three. Each is a signed certificate of analysis from Laboratoire PhytoChemia in Quebec.
- Each reads as lavender, with linalool at 31.4 to 33.6% and linalyl acetate at 27.3 to 30.5%, and each concludes that no adulterant, contaminant or diluent was detected by the lab’s method.
- The page names the plant (Lavandula angustifolia), the part (flowering tops), the method (steam distilled) and the possible countries (Bulgaria, France, Greece, Spain).
- At $9.99 for 10 mL (about $1.00 a mL) it is the least expensive bottle we list.
Trade-offs What to weigh before you buy
- The reports cover three lots, and the newest is dated February 2026. We could not check which lot is in the bottle you receive, so match the lot number on your bottle to the report list, and ask Plant Therapy if it is missing.
- The shop copy makes soft health claims: “a laundry list of therapeutic benefits”, “alleviating anxiety”, and a place in a “natural healing kit for minor cuts and scrapes”. Our lavender article finds that the anxiety trials used a standardized oral capsule, not a diffuser oil, and that no human trial has tested lavender oil on wounds.
- The page suggests diluting to 2 to 5% for skin. Our safety guide gives 2 to 3% for adults and 1% for the face and for children aged 6 to 12. The “KidSafe”, “Pregnancy Safe” and “Pup & Pony Safe” badges are the company’s own labels, not an outside standard.
- The page does not say what the bottle is made of or whether it has a dropper or a child-resistant cap.
What to know Details worth knowing first
Lavender is one of the most popular essential oils and one of the easier ones to check, because its chemistry is well known: mostly linalool and linalyl acetate. Plant Therapy posts a gas chromatography report for the lots it sells, written by an outside lab. We opened all three. Each profile is what true Lavandula angustifolia should look like, and the lab found no adulterant, contaminant or diluent by its method. A gas chromatography profile is a screen, not proof of every kind of adulteration.
A report is only useful if it matches your bottle. Look for the lot number on the label and compare it with the list on the product page. We checked all three posted reports, not the bottle you will receive.
The shop copy promises more than the evidence does. Our lavender article separates what the trials tested from marketing, and our safety guide covers dilution, pets and children. Do not swallow bottled essential oils.
Quality & testing How it measures up against our checklist
- Third-party tested
- Yes
- Tested by
- Laboratoire PhytoChemia (lots L40122R, L40123R, L40124R)
- Certificate of analysis
- Yes
| What we checked | What we found |
|---|---|
| A batch test Verified | Reports for lots L40122R, L40123R and L40124R are linked from the product page, and we opened all three: certificates of analysis (GC profiling and refractive index) from Laboratoire PhytoChemia, dated 2025-07-24, 2025-11-12 and 2026-02-06. Each concludes that no adulterant, contaminant or diluent was detected by its method. PhytoChemia’s site says it is ISO 17025 accredited; we did not check that with an accreditor. |
| Named plants Maker’s claim | Latin name Lavandula angustifolia; flowering tops; steam distilled; Bulgaria, France, Greece or Spain. The three reports are labeled Bulgaria, Bulgaria and Greece. |
| Honest claims Maker’s claim | No promise to cure a disease and no advice to swallow the oil; the page says the International Federation of Aromatherapists does not recommend taking oils by mouth. It does make soft claims such as “alleviating anxiety” and healing minor cuts. |
| Safety information Maker’s claim | Cautions: keep out of reach of children, ask a physician if pregnant or under a doctor’s care, external use only. Dilution advice is 2 to 5% for skin. No cat warning. |
| Dark glass, dropper and lot number Not verified | Not stated on the product page. Lot numbers appear in the report list. |
What the labels mean
- Verified We opened an independent record that confirms it: a certifier’s listing, a regulator’s list or a lab report. It is linked under Sources.
- Maker’s claim The maker says so on its own page or label. We read it but found no independent record.
- Not verified We looked and could not confirm it, or the maker does not say. Treat it as unknown.
