Broad-leaved dock (Rumex obtusifolius)
Broad-leaved dock (Rumex obtusifolius)
This plant is one of the five injurious weeds named in the 1959 Weeds Act and is very frequently seen in pasture land. Its toxic component is calcium oxalate, which can irritate the skin, mouth, tongue, and throat, resulting in throat swelling, breathing difficulties, burning pain, and stomach upset. As oxalates in plants preferentially bind to calcium in the body, regular ingestion in small amounts can lead to calcium deficiency and to the build up of kidney stones if the calcium oxalate formed is not excreted. Due to its unpleasant taste it is, however, not a plant that is regularly consumed. Another name for Broad-leaved dock used to be butter dock because its large leaves were used to wrap and conserve butter.
