Yellow dock leaf

The common dock leaf, Rumex obtusifolia, and the yellow dock leaf, Rumex crispus, are in fact equally common. 

The axillary group represent stipules which stand in the axil of the leaf with the stem. Such may be free axillary structures, arising as distinct processes, or connate, when the two stipules unite at their margins and sheath the stem, as in many species of the Polygonacea such as Buckwheat, Rhubarb, Yellow Dock, Knot Weeds, etc. The sheath formed is called an ochrea. 

Although yellow dock and broad-leaf dock contain small amounts of anthraquinone glycosides (0.35-4.0%), these species have, at most, a mild laxative effect (Demirezer 1994 Demirezer and Kuruuzum 1995 List and Horhammer 1973 Mills and Bone 2005). 

No information on the safety of yellow dock or broad-leaf dock in pregnancy or lactation was identified in the scientific or traditional literature. Although this review did not identify any concerns for use while pregnant or nursing, safety has not been conclusively established.
