Active Compounds

Lemon myrtle contains several naturally occurring plant compounds that contribute to its distinctive aroma and botanical profile. These constituents are typically released through gentle infusion, allowing the leaf’s bright and refreshing qualities to develop.

Some commonly discussed constituents include:

• Essential Oils – aromatic compounds concentrated in the leaves that contribute to the plant’s fresh scent

• Flavonoids – plant compounds present in many herbs, forming part of lemon myrtle’s overall composition

• Terpenes – naturally occurring compounds that contribute to the plant’s aromatic complexity

The preparation method can influence how these compounds are expressed, with shorter steeping times often preserving the herb’s lighter, more delicate notes.
