Active Compounds

Yarrow contains a variety of naturally occurring compounds that contribute to its aromatic and slightly bitter botanical profile.

Some commonly discussed constituents include:

• Flavonoids – naturally occurring plant compounds found in many herbs, contributing to yarrow’s overall botanical composition

• Sesquiterpene Lactones – compounds commonly present in members of the Asteraceae family, contributing to the herb’s slightly bitter taste

• Tannins – compounds that contribute to yarrow’s astringent qualities and are typically extracted during steeping

• Essential Oils – present in small amounts, contributing to the herb’s aroma when infused in hot water

The preparation method can influence how these compounds are expressed, with gentle steeping helping to maintain balance between flavour and aroma.
