Essential oils may look similar in the bottle, but their quality can vary enormously. From the plant source to the method of extraction, there are a few clear markers that separate the best oils from the rest.

Botanical identity & origin

Every good essential oil starts with the right plant. Clear labelling of the Latin name, the plant part used, and the country of origin ensures authenticity and gives valuable context about the oil’s natural profile. The place a plant grows—its soil, climate, and cultivation—shapes its aroma and chemistry.

Extraction & purity

The production method has a direct impact on quality. Steam distillation and cold pressing are the most common processes, helping to preserve delicate aromatic compounds. Purity is equally important: a good oil is 100% natural, free from additives or dilution, and supported by testing to verify authenticity.

Aroma & sensory profile

A genuine essential oil should reflect the character of the plant. For example, true lavender is fresh and floral with a subtle herbaceous note, while citrus oils should be vibrant and bright. Unusual colours, off-notes or flat aromas are warning signs that quality may be compromised.

Sustainability & traceability

Behind every drop of oil is the story of how it was grown or gathered. Responsible sourcing ensures that harvesting supports ecosystems and communities, while full traceability gives confidence that the oil has been handled with care from plant to product.
