Glossary
A plant family is a botanical grouping that helps organize related plants, such as Lamiaceae, Rutaceae, Asteraceae, Myrtaceae, or Apiaceae.
What Plant Family Means
Plants are grouped into families based on botanical relationships. Many aromatic plants used for essential oils belong to families that are familiar in gardens, kitchens, forests, or citrus orchards. For example, lavender, peppermint, basil, rosemary, and thyme all belong to the Lamiaceae family.
Why It Matters
Plant family can help readers understand relationships between oils, but it does not automatically tell you whether an oil is safe or interchangeable. Oils from the same family can smell very different and have different safety notes. Plant family is a helpful clue, not a complete safety guide.
Example in Essential Oil Use
Lemon, sweet orange, bergamot, lime, grapefruit, neroli, and petitgrain all belong to the Rutaceae family, the citrus family. Even so, their plant parts, aromas, extraction methods, and phototoxicity concerns are not identical.
