Plant Therapy Organic Lavender Essential Oil

1. Purity 35% of the rating 5 of 5

   One certified organic ingredient from the flowering tops, two recent lot reports found no adulterant, and an independent lab found the lowest phthalates of 22 oils (40 ppb).

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

   Two lot reports from an ISO 17025 lab paid by Plant Therapy, plus Mamavation’s independent phthalate test of one bottle; its lab is not named and the full data sits behind a free account.

3. Sourcing 15% of the rating 4 of 5

   USDA organic handler listing, and the lots are named as Greece (page: Greece or Bulgaria); no farm or distiller 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 store tags that point to gifted influencer collaborations.

5. Value 15% of the rating 3 of 5

   $11.99 for 10 mL is about $1.20 a mL; the 30 mL bottle is about $0.63 a mL and the 100 mL bottle about $0.43.

The rating, 4.1 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 Essential Oils Organic Lavender KidSafe” had 40 ppb, the lowest of the 22 (one other lavender had 42) and in its “best” group. Bottles were bought from November 2023 to December 2024, so they are not the lots reported above. Open ↗ (opens in a new tab)

• Paid certification USDA Organic Integrity Database (certifier: Ecocert SAS) October 15, 2026

  Lists Plant Therapy LLC (Twin Falls, Idaho) as a certified organic handler since January 2020, with “Lavender Essential Oil” among its certified products. This is a company-level listing about organic handling, not a test for purity or contaminants. Open ↗ (opens in a new tab)

Is the phthalate result for this exact oil?

Almost certainly. Mamavation named “Plant Therapy Essential Oils Organic Lavender KidSafe”, which matches this product’s label. It does not give a lot number, and the bottles were bought before the two lots reported here, so treat it as a result for the product, not for the bottle you will receive.

Does it contain phthalates? Plant Therapy’s plain lavender page says “made without phthalates”.

Mamavation’s lab found traces in every one of the 22 oils it tested, so “without” can only mean none were added. This oil had the least, 40 ppb in total (one other lavender had 42), against 2,181 and 4,674 ppb for two other lavender oils we reviewed. We found no limit for phthalates in essential oils.

Is it really organic?

USDA’s database lists Plant Therapy LLC as a certified organic handler, certified by Ecocert, with “Lavender Essential Oil” in its scope. That is a company listing, not a certificate for a lot, and we did not see which farm grows the lavender.

Is it really pure lavender?

Two 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. Match the lot number on your bottle to the two reports.

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. 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 “Influencer Product Seeding” and “Gifted Collabs”, 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 Plant Therapy’s name on 2026-10-23. We could not search court dockets or FDA’s warning letters.

• It is the only oil on our list with an independent contaminant test of the product itself: 40 ppb total phthalates, the lowest of 22 lavender and peppermint oils Mamavation sent to a lab.
• It is certified organic: USDA’s database lists Plant Therapy as an organic handler, and the oil carries a single ingredient, Lavandula angustifolia, steam distilled from the flowering tops.
• Lot reports are posted for two lots, L50122 and L50123, both from Greece. We opened both. Each is a signed certificate of analysis from Laboratoire PhytoChemia in Quebec, with linalool at 29 to 32% and linalyl acetate at 28 to 30%.
• It costs about 20% more than the plain oil for 10 mL, and larger bottles cost less per milliliter.

• The independent result is one bottle, tested by a consumer group’s unnamed lab, and its full data sits behind a free account. The bottles were bought before the lots reported here.
• Only two lots have reports, and both are from Greece. Match the lot number on your bottle, and ask Plant Therapy if it is missing.
• The shop copy makes soft health claims: “quiet the mind, ease tension, and promote deep relaxation” and “the same calming and skin-loving properties” as the plain oil. Our lavender article finds that the anxiety trials used a standardized oral capsule, not a diffuser oil.
• 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.
