Essential oils: evidence-based guidance

We provide educational information grounded in chemical understanding, documented safety considerations, and professional training standards informed by the Tisserand Institute. This content is non-promotional and does not make therapeutic claims.

What essential oils are

Essential oils are concentrated mixtures of volatile aromatic compounds obtained through physical extraction methods such as steam distillation or cold expression. Each oil contains dozens to hundreds of constituents, and behavior depends on chemical composition—not tradition alone.

How essential oils interact with the body

• Olfactory interaction (primary pathway)

  Inhaled aromatic molecules interact with olfactory receptors. Signals are routed to brain regions involved in emotion and memory, affecting perception and subjective experience.

• Topical application (limited absorption)

  Some constituents can penetrate skin in small amounts. Absorption depends on dilution, molecular size, skin condition, and frequency of exposure.

• Contextual effects

  Environment, expectation, and personal association strongly shape perceived outcomes. These effects are real, but they are not the same as medical treatment.

What essential oils do not do

• Essential oils do not detoxify the body.
• Essential oils do not cure disease or replace medical care.
• Essential oils are not inherently safe because they are natural.
