The subscription concept — why Simply Earth took off
The essential oil subscription market is crowded, but Simply Earth carved out a specific lane that most competitors ignored: teaching people what to actually do with their oils. Where other brands sell bottles and leave you to figure out the rest, Simply Earth built its entire model around guided, hands-on learning. Each month you receive a curated set of oils plus recipe cards that show you how to use them together — not as decoration, but as functional blends for your home, body, and daily routines.
The company launched in 2017 and grew quickly, partly because it timed the market well. The DIY wellness wave was peaking, and a lot of new aromatherapy enthusiasts had drawers full of bottles they had no idea how to combine. Simply Earth answered a real frustration. Instead of selling the fantasy of essential oils, it sold the curriculum. That positioning, combined with an unusually transparent charity commitment (more on that later), gave the brand a loyal following that has sustained it through a period when several competing subscription services quietly folded.
It is also worth noting what Simply Earth is not. It is not positioning itself as a premium apothecary or a clinical-grade supplier. The target customer is someone who is curious, relatively new to aromatherapy, and wants a low-pressure way to build confidence blending oils at home. If that sounds like you, read on. If you are already running a small batch candle business or formulating your own serums, you may outgrow the concept faster than the subscription cost justifies.
What's actually in the Recipe Box each month
Every monthly box contains four full-size essential oils (15 mL each), a set of recipe cards, and a few supporting supplies. The supporting supplies rotate — some months you get a reusable tin, a small roll-on bottle, a glass spray bottle, or a sheet of labels. The exact extras depend on what the recipes call for that month.
The four oils are always chosen to work together as a themed collection. Simply Earth picks a monthly focus — something like fresh citrus cleaning blends, cozy fall diffuser recipes, or garden-inspired body care — and the oils reflect that theme. You are not getting four random bottles. You are getting four bottles that are meant to interact with each other and with the recipes included.
The recipe cards themselves are printed on heavy card stock and sized to fit in a standard recipe box or binder. Most months include five to eight recipes ranging from a simple diffuser blend (two or three oils, a few drops each) to something more involved like a sugar scrub or a room spray. The difficulty curve is gentle but real — the early steps in each card assume no prior knowledge, which beginners will appreciate and experienced blenders may find repetitive.
Sample boxes tour — what four recent months looked like
To give you a concrete sense of what arrives, here is a representative tour of four recent boxes.
Spring Cleaning Box: Centered on household cleaning blends, this box included Lemon, Tea Tree, a rosemary, and a fir needle. Recipes covered an all-purpose countertop spray, a linen refresh spray, a dishwasher tab booster, and a simple diffuser blend for the kitchen. The supporting supplies that month were a 16 oz glass spray bottle and a printed label sheet. A genuinely practical box for anyone trying to reduce synthetic fragrance in their home.
Calm & Unwind Box: This one leaned into evening routines. The four oils were Lavender, a vetiver, a Roman chamomile, and a bergamot. Recipes included a pillow spray, a roller blend for tension, a bath salt base, and a diffuser combination for winding down after work. The chamomile was the standout — a small amount goes a long way and it is an oil many beginners have not yet experimented with.
Breathe Easy Box: A respiratory-themed winter box featuring Eucalyptus, Peppermint, a ravintsara, and a lemon myrtle. Recipes covered a shower steamer, a chest rub base (for topical use with a carrier oil, not ingestion), an inhaler stick, and a diffuser blend for congested spaces. The shower steamers were a particular hit based on community feedback — easy to make, satisfying to use, and visually appealing enough to give as gifts.
Fresh Citrus Box: A summer-leaning collection built around bright, energizing scents — grapefruit, Lemon, a lime, and a sweet orange. Recipes included a deodorant base, a countertop spray, a hand lotion mixer, and a diffuser blend. Less surprising than some boxes, but solid foundational oils for anyone building their first collection.
Oil quality and GC-MS transparency
Simply Earth states that its oils are 100% pure, undiluted, and free from additives or synthetic extensions. The company publishes GC-MS (gas chromatography–mass spectrometry) test reports on its website, accessible by batch number. You can look up the specific lot number on your bottle and pull the corresponding report, which lists the chemical constituents and their percentages.
This level of transparency is meaningful. GC-MS testing is the industry standard for verifying purity, and not every brand makes these reports publicly available. Simply Earth does. The reports are readable if you know what to look for — linalool and linalyl acetate percentages for lavender, for instance, or limonene content in citrus oils — though the company does not explain how to interpret them, which is a missed educational opportunity given their teaching-first brand identity.
One honest caveat: third-party independent testing, meaning testing commissioned by someone other than the brand itself, is not something Simply Earth publicly highlights. The GC-MS reports available appear to be from testing they commission. That is standard practice and not a red flag, but it is worth knowing if you are the type of buyer who weights independent verification heavily. Brands like Plant Therapy have occasionally invited external scrutiny in ways that go a step further.
In terms of sensory quality, the oils in Simply Earth boxes are consistently fresh-smelling and well-sourced. Nothing in several years of community reviews suggests adulteration or weak dilution. They perform well in diffusers and in the recipes provided.
Recipe cards — are they practical or Instagram fluff?
This is a fair question to ask of any lifestyle subscription, and the honest answer is: mostly practical, with some caveats.
The recipes are tested and functional. The diffuser blends work. The cleaning sprays clean. The body care recipes — the scrubs, the roller blends, the shower steamers — produce usable products. Simply Earth does not appear to be designing these cards primarily for photography, which is a real risk in the subscription box world.
That said, a few recipes each month feel like padding. A two-ingredient diffuser blend stretched across a full recipe card with lifestyle photography is not really a recipe — it is a suggestion. The more interesting cards are the ones that involve three or more steps and teach you something about why you are combining those specific oils. Those are rarer, but they are in there.
The cards also include brief notes about each oil's scent profile and general character, which is genuinely useful for beginners building their sensory vocabulary. Knowing that vetiver is earthy and grounding while bergamot is citrusy and slightly floral helps you start to internalize the logic of blending rather than just following instructions by rote. Use the Blend Builder to experiment beyond the cards once you have a feel for how the oils interact.
The Big Bonus Box — what arrives on your first month
New subscribers receive a Big Bonus Box alongside their first monthly box. Simply Earth values this at around $150, though the actual market value depends on what happens to be included when you sign up — the contents rotate.
Typically the Big Bonus Box contains a set of glass roller bottles (usually ten), a set of small amber glass bottles with dropper caps, a fractionated coconut oil or similar carrier oil, a set of blank labels, and an additional oil or two not included in the regular monthly box. Some versions have also included a small essential oil storage case or a recipe binder insert.
Is it actually worth $150? That is a stretch if you price out every individual item at retail. The roller bottles and amber bottles are functional but not premium. The carrier oil is a usable size. As a starter kit for someone who genuinely has nothing at home, it provides real value — you would otherwise need to purchase all of these items separately before you could use your first box of oils. As a marketing hook, it works because it solves the immediate friction of getting started.
Cost analysis: monthly fee vs. loose equivalent from Plant Therapy
As of early 2026, the Simply Earth Recipe Box runs approximately $39 per month with a subscription. That breaks down to roughly $9.75 per 15 mL bottle, plus the recipe cards and monthly extras.
For comparison, Plant Therapy's 15 mL bottles in a comparable quality tier typically run between $8 and $18 each depending on the oil, with common oils like Lavender and Lemon toward the lower end and specialty oils like Roman chamomile or vetiver toward the higher end. If you were to purchase the four Simply Earth oils individually from Plant Therapy, you might spend anywhere from $35 to $60 depending on the specific oils that month.
This means Simply Earth is roughly price-competitive for common oils and actually a decent value when the month's selection includes a pricier specialty oil. The recipe cards and supplies add value that is hard to price directly but real for beginners. Where the math gets harder to justify is when you are an experienced blender who already owns most of the oils in a given month's box and has no use for another set of roller bottle labels.

Giving back to anti-trafficking charities — the claim and what it means
Simply Earth donates 13% of every sale to organizations that work on anti-human-trafficking efforts. This is a core part of their brand story and they are consistent about naming the partners they support rather than leaving the commitment vague.
This is not a gimmick donation — 13% is a meaningful percentage, not a rounding-error contribution. The company has been transparent about which organizations receive funds and has maintained this commitment since launch, which suggests it is structural rather than promotional.
Whether this factors into your purchase decision is personal. But it is worth acknowledging that it is a genuine differentiator, not marketing copy that evaporates under scrutiny.
Strengths
Beginner education. Simply Earth is one of the few essential oil brands that treats education as a core product rather than an afterthought. The recipe cards, the themed curation, and the guided approach to using oils together genuinely accelerates the learning curve for new aromatherapy enthusiasts. If you have never blended before, this subscription shortens the confused-drawer-of-bottles phase considerably.
Ritual and consistency. There is real value in having a monthly reason to engage with your oils. Many people buy essential oils enthusiastically and then let them sit. A subscription creates a recurring ritual — unboxing, reading the cards, trying the recipes — that keeps the practice alive. This is underrated as a feature.
Scent variety. Because Simply Earth curates thematically, you are exposed to oils you might not have thought to buy on your own. That ravintsara or lemon myrtle you receive in a winter box may become a staple. Broadening your scent vocabulary through guided exposure is one of the more organic ways to learn aromatherapy.
Weaknesses
Rare and specialty oils are infrequent. If you are drawn to aromatherapy because of its more unusual botanical offerings — helichrysum, blue tansy, CO2 extracts, absolute-style florals — you will not find them here often. The box skews practical and approachable, which means it skews toward oils that are easy to source, pleasant for general audiences, and safe for straightforward home use. That is not a flaw for beginners, but it is a ceiling for anyone pushing further into the craft.
Intermediate users may outgrow it quickly. After six to twelve months of consistent use, you will likely have a solid foundation of the core oils and a working understanding of how to combine them. At that point, the subscription may start to feel repetitive. You are paying for curation and education — once you have internalized enough to curate your own blends and source your own oils, the value proposition narrows significantly.
Who should subscribe and who should skip
Subscribe if: You are new to essential oils and want structured guidance rather than a pile of bottles and a YouTube rabbit hole. You appreciate the ritual of a monthly delivery. You want a low-commitment way to try a range of oils before building your own collection. You care about the charitable giving component.
Skip if: You already own more than twenty oils and blend regularly. You prefer to hand-select every oil you buy based on sourcing and constituent profiles. You are primarily interested in rare or high-end oils. You are on a tight budget and can invest the time to research and buy oils individually — you will likely get more variety for the same money.
