Rumex Patientia is found in wet, weedy places on relatively rich soils, along roads, near forests, in the oak belt in the northeastern part of the country. It is cultivated, but it is also self-healing.

The roots (Radix patientae) and folia patientae on the flank are used. The leaves are picked June - August, and the roots - September - November (after the fall of the frosts) or March - April at the beginning of the vegetation. The roots are dug, cleaned by the overhead parts and the small roots. Leaves are harvested at the beginning of the flowering of the plant. The younger leaves are berating.
