Habitat: Yellow dock is indigenous to Europe and parts of Africa, but like many medicinal herbs it has been carried beyond its native borders by travelers.

Description

Yellow dock is a perennial herb belonging to the Polygonaceae family, commonly referred to as the knotweed family. This family also includes rhubarb, buckwheat, and sorrel. Mature yellow dock stands no more than 4 feet tall and is reddish-brown in color.

Its common name refers to the yellow taproot rather than the flowers or leaves. Its other common name, curly dock, refers to the willowy, undulating leaves.

The leaves are grouped around a central point at the base of the stem. Plants produce light green floppy flowers between early spring and late autumn. The flowers are arranged in loose clumps along a stalk above the leaves.

Plant Parts Used: Roots, leaves, and seeds. The root is dug up in autumn, chopped and then dehydrated for storage.

Therapeutic and Traditional Uses, Benefits and Claims of Yellow Dock

It is the taproot of yellow dock that is most commonly used in herbal remedies as it is rich in many compounds known to have cleansing and calming qualities as well as minerals such as calcium, iron, magnesium and phosphorous.

Yellow dock contains a number of anthraquinones, including emodins, which are known for their laxative action. Though small doses of yellow dock can be used as an herbal remedy for diarrhoea, higher doses actually cause diarrhoea.

Dosage and Administration

Dosage is critical as always as it can mean the difference between a natural remedy for diarrhea and severe vomiting, or worse.

The root is generally taken as tea up to three times daily. One to two teaspoons of dried root in approximately two cups of water is steeped for ten minutes.

The root can also be found in a tincture form with the recommended dosage up to 2 tsp, three times daily.

For natural relief of upper respiratory disorders, the yellow dock root can be prepared as a syrup which is taken one teaspoonful at a time.

The liquid is strained and dark honey (1/2 cup), blackstrap molasses (1/2 cup), and maple syrup (1 tsp) are added to the liquid and then blended into a smooth thick syrup. Vanilla can be added for flavor if desired.

To prepare a poultice, steam the soft leaves and place them directly on the affected area.
