How to Choose a Quality Essential Oil: The Complete Guide
How to Choose a Quality Essential Oil: The Complete Guide
Let me return to the topic of choosing essential oils. I realized, in fact, during the last event, how necessary it is to give clear and precise indications on this topic.
Why? Because everything we breathe in, apply to our skin, or ingest enters our body. In our bloodstream, passing through some of our organs. If these substances are not of good quality, they risk doing us more harm than good. That is why I want to share with you some fundamental criteria for choosing pure and safe essential oils.
The selection of brands and products on the Euodia website has been made with rigorous criteria , based both on technical factors (purity, chemotype, biotype, extraction method) and on my direct experience in the use of essential oils . Each oil you find on our e-commerce has been chosen to offer you the highest quality, without compromise.
Here's what to check before buying an essential oil and why our selection meets these criteria.

🔎 1. Purity: Must be 100% Natural
✔ A quality essential oil must be 100% pure and natural , without chemical additives or synthetic substances.
✔ No to oils diluted with vegetable oils or other substances: always read the label !
✔ Be wary of products at rock-bottom prices: they often contain solvents or artificial fragrances.
👉 On Euodia you will find only pure oils, without compromising on quality.
🌿 2. Chemotype and Biotype: Why They Are So

Important?
✔ The chemotype (CT) indicates the dominant chemical composition of the oil and determines its therapeutic properties.
✔ The biotype refers to the botanical variety of the plant and its growth environment, influencing the quality of the oil.
-
🔎 Examples of chemotype and biotype:
Rosmarinus officinalis CT Cineole → Energizing, useful for the respiratory tract. - Rosmarinus officinalis CT Verbenone → More delicate, useful for liver cleansing.
- Lavandula angustifolia (mountain biotype) → Sweeter aroma and higher concentration of relaxing esters.
👉 Each oil on Euodia is chemotyped and the biotype is indicated when available.
🌎 3. Full Botanical Name and Certified Origin


✔ A quality essential oil must report the botanical name in Latin , to avoid confusion between different species.
✔ Geographical origin is also essential: the same plant can have very different compositions depending on the climate and soil in which it grows.
👉 We only select oils with clear traceability and coming from the best cultivation areas.
🔬 4. Extraction Method and Certifications


✔ Essential oils must be extracted by steam distillation (for plants) or cold pressing (for citrus fruits).
✔ They must be free of chemical residues and preferably come from organic or wild cultivation .
✔ The presence of GC-MS analysis (gas chromatography-mass spectrometry) is an added value.
👉 We have selected only brands that guarantee these quality standards.
💰 5. Right Price: Beware of "Cheap" Oils
✔ Producing authentic essential oils has a cost. One liter of rose essential oil, for example, requires about 4 tons of petals !
✔ If all oils from a brand have the same price, they are probably not authentic.
✔ Be wary of products sold as “essential oils” for a few euros: they could be synthetic fragrances.
👉 On Euodia you can find high quality essential oils, without compromise, at the right price.
🚫 Buying Without Constraints: An Added Value!
Many aromatherapy brands sell their oils with subscription systems or purchase restrictions . This forces consumers into repeated , often unnecessary, expenses.
✔ No mandatory registrations! On Euodia you can purchase in complete freedom , without having to sign up for subscription plans.
✔ No predefined packages! Choose only the oils you really need.
✔ No to aggressive marketing strategies! We believe in transparency and quality, not in sales pressure.
👉 Buy whenever you want, without constraints, with the certainty of receiving carefully selected products.
