Sorrel (Rumex acetosa L.): Not Only a Weed but a Promising Vegetable and Medicinal Plant.

Sorrel (Rumex acetosa L.) is a perennial, dioecious herb occupying a variety of habitats. Sorrel has been utilized as a wild gathered plant for thousands of years and as a cultivated plant for centuries. Primarily roots but also other tissues have been used in folk remedies since ancient times. In recent investigations, different phytochemical and pharmacological activities of Rumex have been analyzed, and many bioactive compounds have been detected. Sorrel is also a tasty plant and its leaves are a good source of macronutrients and micronutrients. However, the presence of high levels of oxalic acid reduces the bioavailability of some minerals, especially calcium, when using uncooked plant parts. Further investigations on different sorrel compounds are needed to show their true effect. It is beneficial that sorrel is easily propagated and there are no serious insect or disease problems. A few types of R. acetosa seeds are presently available commercially, including wild types and a few cultivars. [ABSTRACT FROM AUTHOR]
