Herbarium of the Ancients — Detailed Record

Sonchus arvensis

Please read before use: the information below describes traditional and informational uses — it does not replace the advice of a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment, or use in children, seek advice before use.

The milky sap may cause mild skin irritation in some individuals; a patch test on a small area is advisable before any application. As with any wild plant in the Asteraceae family, cross-allergy is possible in people sensitive to ragweed, daisy, or dandelion. Prolonged internal use or therapeutic use should be discussed with a healthcare professional, as traditional data remains limited. Avoid harvesting near roadsides or treated areas, as the plant tends to absorb soil pollutants.

Infusion — Fresh or dried leaves

Leaf infusion

Pour simmering water over chopped leaves and let steep for about ten minutes, covered. Strain before drinking, optionally sweetened with a little honey. One tablespoon of dried leaves per cup, one to two cups per day.

Salad — Young leaves

Leaves in wild salad

Harvest young leaves before flowering, wash thoroughly, then add raw to a salad, as you would with dandelion. They can also be lightly cooked like spinach. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.

Compress — Stem (latex)

Local application of latex

Break a fresh stem and apply a drop of latex directly to the affected area, avoiding mucous membranes and the eye contour. This use remains occasional and rooted in folk tradition. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.

Where to find it

Sourcing the plant

Field sowthistle grows spontaneously in meadows, embankments, and gardens throughout Europe; it is rarely found in herbal shops, with wild harvesting remaining the most common practice.

Harvest season

When to harvest

Young leaves are best harvested in spring, before the plant's summer flowering.
