Dock is in the same family as rhubarb.
The root is a source of yellow dye.
The juice has a cooling effect on stings.
(lecture by Charlotte Clarke, author of Edible and Useful Plants of
California, April 1987.
Rumex species have been known to cause hay fever and asthma.
They have also been known to accumulate free nitrates and soluble
oxalates in quantities capable of causing death or distress in cattle.
Animals usually will not eat them. (Fuller 210,381,386).
The Miwok Indians of central California cooked and ate the leaves of this
non-native plant. (Campbell 140).
About 140 species, widely distributed.
(Munz, Flora So. Calif. 705).
About 24 species in California. (Fuller
