The Component Database

A reference library of the chemical components inside essential oils: what each one is, what published research has observed it do, and where the evidence lives. Look up a component, follow a therapeutic property to every component that carries it, and read the research behind each claim.

The Component Database's library shelf: the search bar, browse tabs for components, families, and properties, an A-to-Z letter strip, and component data sheet cards showing each component's family, property count, and study count

The library, as you’ll use it: browse A to Z, by family, or by property.

About this reference

Open a data sheet and the whole picture is in front of you: safety notes first, then the research findings, each cited line by line, then the therapeutic properties that evidence supports. Or start from the other end. Every property has its own page gathering each linked component’s finding, quoted from its data sheet with its citations.

The library is built to be searched, not read cover to cover. Full-text search reaches across components, properties, lessons, and the glossary, and you can browse by name, chemical family, or property. When a term from the research stops you, the glossary explains it in plain language.

This is a living reference. New components and new research land in your library, not in a new edition, and your access never expires.

Inside the library

What’s inside.

01

75 component data sheets

Each with its research findings cited line by line, safety notes leading, and the therapeutic properties the evidence supports.

02

79 therapeutic properties

Each on its own page with the evidence gathered: every linked component’s finding, quoted from its data sheet with its citations.

03

A plain-language glossary

The scientific terms the research uses, defined so they stay out of your way.

04

Full-text search

Search across components, properties, lessons, and the glossary, plus browsing by name, chemical family, and property.

05

Five orientation lessons

Short lessons on reading data sheets and research with confidence.

06

Every future addition

New components and new research land in your library, not in a new edition.

Research findings describe published studies, many in laboratory or animal models at doses beyond aromatherapy practice; they are signposts for understanding, not instructions for use.

Getting started

Five short lessons, then the library is yours.

The course opens with a short orientation on finding your way and reading the research with confidence:

  • Welcome to the Component Database
  • How to read a component data sheet
  • Finding what you need: browse and search
  • Reading the research
  • Safety, dilution, and use

Karen keeps the library growing. She has edited the collection deeply and added many new components, and she is the reason new research keeps landing on the shelves.
