Can TTO only be sourced from Melaleuca alternifolia?
Fact: The international standard for TTO does not specify which species of Melaleuca must be used to produce the oil. It does however provide compositional limits for 15 of the more than 100 components that make up TTO. Most TTO is produced from Melaleuca alternifolia grown on plantations but other plants that may produce suitable oils include M. dissitiflora and M. linariifolia.
