Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Rumex aquaticus - L.

Common Name Red Dock, Western dock
Family Polygonaceae
USDA hardiness Coming soon
Known Hazards Plants can contain quite high levels of oxalic acid, which is what gives the leaves of many members of this genus an acid-lemon flavour. Perfectly alright in small quantities, the leaves should not be eaten in large amounts since the oxalic acid can lock-up other nutrients in the food, especially calcium, thus causing mineral deficiencies. The oxalic acid content will be reduced if the plant is cooked. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition[238].
Habitats Shallow water at the margins of swamps[17]. Fields, meadows and ditches[4].
Range Europe, including Britain but absent from Italy and the Balkans, to N. Asia.

It can cause or relieve diarrhoea according to the dose, harvest time and relative concentrations of tannin(astringent) and anthraquinones (laxative) that are present[222]. It is used internally in the treatment of piles, bleeding of the lungs, various blood complaints and also chronic skin diseases[4, 238]. Externally, it is applied to various skin diseases, ulcers etc[4]. The root has been used with positive effect to restrain the inroads made by cancer, being used as an alterative and tonic[4]. The root is harvested in early spring and dried for later use[4]. Some caution is advised in its use since excess doses can cause gastric disturbance, nausea and dermatitis[222, 238].
