Plant Family: 

Polygonaceae

 

Habitat & Cultivation: 

Yellow dock is native to Europe, Asia, Africa, and North America (Vasas, Orban-Gyapai, & Hohmann, 2015). Yellow dock does grow in the United States (it is largely considered a weed here) and has an affinity for wet soil. 

Yellow dock is grown and sourced in the United States by most suppliers here. We have a local apothecary that sources hers from the PNW (in Bellingham) although she is a small local business serving the Skagit Valley which is not a large community. Herb Pharm states that they get their Yellow dock from the US as well, although it is not one of the herbs they grow on their farm in Oregon. Other bigger suppliers state that they source their yellow dock from Maine, and even Croatia.

Energetics: 

Yellow dock is bitter, astringent (dry), cooling, and pungent (Frawley & Lad, 1986). It is Vata-aggravating, and more diminishing to Pitta and Kapha (Frawley & Lad, 1986). High-Pitta is indicated for this herb, whilst high-Vata is actually a precaution for use (Frawley & Lad, 1986)

 

Safety: 

Pregnancy category B2 and Lactation category CC (compatible with lactation but use with caution due to anthraquinone glycosides which may be excreted in small amounts in breast milk). Contraindicated in cases of intestinal obstruction or gastrointestinal inflammation. Yellow dock is a anthraquinone-containing laxative herb which has a stimulant and irritant effect in the large intestine. Due to this laxative effect, yellow dock should be used for short term use only and may have the following effects in the body: electrolyte imbalance/dehydration, increase potassium depletion and decrease gastrointestinal transmit time/absorption of medications. Lastly, high levels of oxalic acid may cause kidney stones if consumed in large quantities. (Mills & Bone, 2005)
