The benefits of essential oils are directly related to their purity and quality. dōTERRA Essential oils are potent ensuring that users get the maximum benefit from each drop.

 Consistency

dōTERRA Essential oils have consistent chemistry, that you can rely on bottle to bottle, batch to batch, year to year.

The Hidden Dangers of Low-Quality Essential Oils

Cheap essential oils also smell nice!

Many people simply want a pleasant scent at home and appreciate a lower price. 

However, cheap essential oils are often fabricated, impure, and inconsistent, which means they may contain unknown or potentially harmful substances. 

While they might smell good, these oils won’t provide safe or effective results.

Using low-quality oils can pose serious safety risks. Without purity, you can’t be certain what you’re exposing your body to—or how it might impact your health.

Why does it all matter?

Without purity you don´t know what you are putting on your body on your skin and and what goes in your lungs. Without knowing what is in the bottle you are not safe.

What should consumers do?

Consumers need to be very selective. Essential oils enter your lungs, skin, and body, influencing your chemistry. 

These plants have been with us for centuries, and when distilled properly—without adulteration or synthetic additives—their oils can truly support your health and wellness. 

To get the full benefits, it’s essential to choose oils that are pure, natural, and consistent.

What about doTERRA?

dōTERRA puts tremendous effort into delivering pure, adulteration-free essential oils with consistent chemistry you can trust—bottle to bottle, year after year.

Did you know?

 Think about the peppermint flavor in your toothpaste or gum—did you know it’s often made from synthetic compounds? Peppermint oil is broken down into individual chemicals, then cheaply reassembled through simple chemical processes to mimic the scent. The result? A fake, chemically manipulated product that smells similar but lacks the natural synergy and therapeutic benefits of pure, whole peppermint essential oil.

 Dr. Prabodh Satyal has published several studies revealing widespread adulteration in the essential oil industry. One of the most striking examples is birch essential oil. In many cases, products labeled as "birch" were actually made from wintergreen or, more alarmingly, synthetically produced from expired aspirin. The common link? Methyl salicylate—the main compound found in both wintergreen and birch. Manufacturers can easily convert aspirin into methyl salicylate through a simple chemical process. It’s cheap, smells similar, but has no true connection to the birch plant.

 The benefits of essential oils come from their precise chemical composition. When the composition is correct, the oil can offer powerful, positive effects. According to the International Organization for Standardization (ISO), the acceptable range for certain active compounds is between 20% and 40%—which means one bottle may contain only half as much, of a key ingredient as another. That’s why purity and consistency matter.

From Plant to Bottle: The Science Behind dōTERRA’s Consistency

dōTERRA ensures that every bottle of essential oil is not only pure but also consistent—year after year, batch after batch. This is made possible through their unique approach called Co-Impact Sourcing® and a commitment to turning essential oil distillation from an art into a science.

At distillation facilities like Esseterre in Bulgaria (for lavender) or in Kenya (for geranium), dōTERRA follows precise, repeatable protocols—using the same amount of plant material, at the same temperature, pressure, and distillation time every single time.

Take lavender as an example:
Over the past eight years, the linalool content—a key active compound—has remained remarkably consistent, averaging around 33%, with only a 1% variation. That level of consistency is unmatched in the industry.

By using Co-Impact Sourced blending to minimize variation and applying scientific precision to the distillation process, dōTERRA is not just delivering pure essential oils—they're delivering some of the most consistent oils on the market.

This dedication to quality is further supported by dōTERRA’s Certified Pure Therapeutic Grade® (CPTG®) standard, which pairs rigorous internal testing with third-party verification to ensure each oil meets strict purity and potency requirements.

Each bottle includes a unique identifier, allowing you to easily access and verify its certificate of purity and quality on the Source to You website—so you always know exactly what you’re putting on or in your body.

Roseman University Researchers Study dōTERRA Essential Oils

The results of our research show that the implications of ‘The Oil Effect’ are significant,” says Dr. Le.
His studies suggest that essential oil quality depends on both chemistry and biochemistry, and that advanced biochemical analysis is essential to truly evaluate an oil’s quality.

essential oils: scent or science?

Main mechanisms of essential oils

Research data shows that the multiplicity of pharmacological properties of essential oils occurs due to the chemical diversity in their composition and their ability to interfere with biological processes at cellular and multicellular levels via interaction with various biological targets. 
PubMed/MEDLINE, 2023

Their pharmacological actions

The lipophilic profile of these components contributes to their ability to penetrate cells and tissues to reach biological targets and carry out the pharmacological response. Their constituents cross the biological membranes of infected cells and/or microorganisms with ease and cause their death. ​PubMed/MEDLINE, 2023​​​

Their pharmacological profile

The pharmacological profile of essential oils includes antimicrobial, anti-inflammatory, antitumor, antioxidant activities, among others. Essential oils are composed of approximately 20–60 components at different concentrations, but some of them may contain more than 300 different substances. PubMed/MEDLINE, 2023

Their pharmacological actions

The antioxidant activity of some constituents of Essential Oils suggests their possible action in restoring balance in pathological disorders associated with oxidative stress, including inflammatory and tumoral processes. ​PubMed/MEDLINE, 2023​​

Purity

What is purity?

Purity in terms of essentials oils can be defined as lack of adulteration.

Why does purity matter?

Without purity, you don’t really know what you’re putting on your skin, into your body, or breathing into your lungs. Without knowing what’s in the bottle, you can’t trust that it’s safe.

Consistency

What is consistency?

Consistency means the chemical potency in every drop remains virtually the same—year after year, batch after batch.

Why does consistency matter?

Consistency is crucial for dosage. Without it, consumers can’t reliably use essential oils to achieve the same effect every time—batch to batch, year to year.

 "The term essential oil was created in the 16th century and refers to the theory of “Quinta essentia”. Paracelsus defined the role of alchemy by developing plant extracts and herbal medicines." 

Paracelsus (1493–1541): German-Swiss alchemist and physician

 Paracelsus believed that the distillation process extracted the most significant part of the plant, namely, the “quintessence for healing” or “plant’s soul”, separating the “essential” constituents from the “nonessential. 

Paracelsus (1493–1541): German-Swiss alchemist and physician

 An “essential oil” can be defined as a “product obtained from a natural raw material of plant origin, either by distillation with water or steam, or from the epicarp of Citrus sp. fruits by a mechanical process, or by “dry distillation”. Essential oil is then separated from the aqueous phase by physical means.

Three easy ways to use essential oils

  • Aromatic

    Breath in directly or use diffuser

  • Internal

    Place a drop under tongue, in veggie cap or in water

  • Topical

    Apply to reflex points, or bottom of feet or specific areas

Essential oil industry

What does the essential oil market want?

The essential oil industry want something that is chemically indistinguishable from something that is pure and natural, but is not pure and natural.

What concerns does adulteration brings up?

It brings up concerns from a transparency, safety and efficacy perspective.
