Parts used and where grown
Yellow dock is found in many places throughout North America. The root of the plant is used
in herbal medicine.
Yellow dock has been used
in connection with the following conditions (refer to the individual
health concern for complete information):
Historical or traditional use (may
or may not be supported by scientific studies)
Yellow dock has a long history of use as an alterative. Alterative herbs have nonspecific
effects on the gastrointestinal tract and the liver. As a result, they are thought to treat
skin conditions attributed to toxic metabolites from poor digestion and poor liver function.
Active constituents
Yellow dock contains relatively small amounts of anthraquinone glycosides, which may
contribute to its mild laxative effect.1 It is also thought to stimulate bile
production. It is often used as a digestive bitter for people with poor digestion. No human
studies have been done on its use as medicine.
How much is usually taken?
A tincture of yellow dock, 1/4–1/2 teaspoon (1–2 ml) three times per day, can
be used.2 Alternatively, a tea can be made by boiling 1–2 teaspoons
(5–10 grams) of root in 2 cups (500 ml) of water for ten minutes. Three cups (750 ml)
may be drunk each day.
Are there any side effects or interactions?
Aside from mild diarrhea or loose stools in
some people, yellow dock is rarely associated with side effects.3
At the time of writing, there were no well-known drug interactions
with Yellow Dock.
