Grown, harvested and bottled on a single organic farm in England, this traditional liquid tincture is about as close to the plant as a supplement gets. It suits anyone who prefers drops to capsules, or who likes the flexibility of adjusting their amount from day to day.

The 50ml amber bottle contains organic milk thistle seed (Silybum marianum) extracted in organic alcohol (25%) and water, at a strength equivalent to 1000mg of seed per 1ml. The seeds are hand sown in spring and hand picked at the end of summer, a slow process Viridian believes preserves the character of the plant. Take 15 to 30 drops in a little water or juice, two to three times daily. Certified organic by the Soil Association. Seek professional advice during pregnancy or breastfeeding.
