Yarrow Complex takes its name from the herb Achillea millefolium (Yarrow), found in this fresh herb tincture combination. Yarrow is one of the digestive herbs used traditionally. It is a small plant with finely divided leaves – these ‘thousand leaves’ are the origin of part of its botanical name ‘millefolium’. The botanical and common names of the herbs found in Yarrow Complex are Achillea millefolium (yarrow), Taraxacum officinalis (dandelion), Melissa officinalis (lemon balm), Gentiana lutea (great yellow gentian) and Carduus benedictus (blessed thistle).
