Plant Therapy Lavender Essential Oil

1. Purity 35% of the rating 4 of 5

   One ingredient, Lavandula angustifolia from the flowering tops, and three outside-lab lot reports found no adulterant by a screening method; they cover three lots, not every bottle.

2. Batch testing 25% of the rating 4 of 5

   Three lot reports from an ISO 17025 lab, published but paid for by Plant Therapy; nobody independent has tested this oil, though its organic sister oil had the lowest phthalates of 22 in a Mamavation test.

3. Sourcing 15% of the rating 3 of 5

   Bulgaria, France, Greece or Spain depending on the lot, and the reports name the country; not organic, and no distiller or farm is named.

4. Trust 10% of the rating 3 of 5

   No Prop 65 notice or lawsuit found and one 2020 CPSC recall of five wintergreen oils (not lavender) for non-child-resistant caps, with free replacement caps as the remedy; points off for soft health claims, “KidSafe”, “Pregnancy Safe” and “Pup & Pony Safe” badges it awards itself, and a “made without phthalates” line that no independent test checks for this oil.

5. Value 15% of the rating 3 of 5

   $9.99 for 10 mL is about $1.00 a mL; the 30 mL bottle is about $0.60 a mL and the 100 mL bottle about $0.40.

The rating, 3.6 of 5, is the weighted average of these scores. See how we rank essential oils and our standard.

• Independent Mamavation with Environmental Health News (Mamavation earns affiliate income) February 2025

  Sent 22 lavender and peppermint oils from 11 brands to an EPA-certified lab (not named) and tested them for 15 phthalates. All 22 had traces, from 40 to 13,029 ppb in total. Plant Therapy’s Organic Lavender, a sister product to this oil, had 40 ppb, the lowest of the 22. This non-organic oil was not tested. Bottles were bought from November 2023 to December 2024.

Is it really pure lavender?

Three reports from an ISO 17025 lab show a true lavender profile and no adulterant by its method. A gas chromatography profile is a screen, not proof: a 2021 University of Mississippi study (opens in a new tab) of 72 lavender oils found standard methods are not enough to catch adulteration with synthetic compounds and built a stricter test. The reports cover three lots, so match the lot number on your bottle.

Does it contain phthalates? The page says “made without phthalates”.

Mamavation’s lab found traces of phthalates in all 22 lavender and peppermint oils it tested, including 40 ppb in Plant Therapy’s Organic Lavender, the lowest of the group. This non-organic oil was not tested, so “without” can only mean none were added. We found no limit for phthalates in essential oils.

Is it safe on skin, for children, in pregnancy or around pets?

The “KidSafe”, “Pregnancy Safe”, “Nursing Safe” and “Pup & Pony Safe” badges are the company’s own, not an outside standard, and the page says its KidSafe products are not endorsed by the Child Accident Prevention Foundation of Australia. Lavender oil can sensitize skin once it oxidizes: 2.8% of dermatitis patients (opens in a new tab) reacted to oxidized lavender oil in one patch-test study. Dilute it, and see our safety guide. Ask a vet before using it around pets.

Does Plant Therapy gift or pay influencers?

Probably. Its store data tags this oil “Gifted Collabs” and its organic sibling “Influencer Product Seeding”, which suggests it sends free product to creators. We found no public list of partners or terms, so we cannot say who, or how they disclose it.

Any recalls, Prop 65 notices or lawsuits?

One recall, and not of this oil. In March 2020 CPSC announced a recall (opens in a new tab) of about 34,000 bottles of its wintergreen oils and blends (sold before September 2019) because the caps were not child-resistant; they contain methyl salicylate. No injuries were reported and the remedy was a free child-resistant cap. Lavender was not in it. California’s Prop 65 notice list and FDA’s recall database held nothing under its name on 2026-10-23. We could not search court dockets or FDA’s warning letters.

• 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, and the larger bottles cost less per milliliter.

• 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”, “supports mental health” 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 page does not say what the bottle is made of or whether it has a dropper or a child-resistant cap.
