• Essential plant compounds found within the aerial portions of the plant

These compounds are typically extracted through herbal infusions, tinctures, or decoctions, depending on the preparation method.

Bitter herbs such as Blessed Thistle are often prepared as teas or included in botanical blends where their flavour contributes to the overall herbal formula.
