Reliable and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary

minimal or no scientific evidence. For a supplement, little scientific support and/or minimal
health benefit. | |
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 diarrhoea 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.
