This page only says where information belongs. It is not treatment advice, and it is not a dilution chart to copy. For a personal health situation, speak with a qualified professional.
How to read a dilution percentage
A dilution percentage says how much essential oil is in a finished blend. 1% means one part essential oil in every hundred parts of the blend; the rest is carrier. It is a way to read a label. It is not a promise to a particular person, and it is not a score of effect.
A teaching page may explain how to read the number. A consumer product page does not publish a formula ratio. A teaching example is not your dose.
Where phototoxicity notes belong
Some peel oils can make skin more uncomfortable in sunlight. That sentence belongs on that oil’s profile or safety block, near the name, not only in the site footer. The atlas puts the profile before the story so this kind of note is seen first.
This page does not list hours-after-sun for each oil, and it does not copy outside charts.
Where notes for children and pregnancy belong
Notes for children, pregnancy, and sensitive skin also sit beside that oil, in a short sentence. This site does not open a children’s column. If an oil is not mentioned here, that is not permission to use it.
How to read a GC report
A gas chromatography (GC) report describes the volatile constituents measured in one batch. A peak’s percentage is its share of that measurement, not a strength of effect. Without that batch’s report, we do not add the module, and we do not invent test figures. Latin names and chemical names stay as printed on the report.
How this sits with the atlas
Each atlas essay places a short profile before the opening story, with one line back to this page. Product pages keep their own safety block. This page does not add a long product essay, and the atlas does not open a new purchase entry.
The atlas essays are in Aroma Atlas. The plant-oil essays are in Oilology.
