Prep notes
The spotted seed. Fibre and iron like a small oilseed. Silymarin is not in the USDA table — this is the seed as food.
Season
Year-round grocery when this catalogue row is listed as common / pantry.
Caution
Grocery / shop food data only. Not a wild forage guide. Thrive shows composition curiosity — not medical advice.
