It never ceases to amaze me how easy is to overlook a common weed. I never gave dock a glance before I came to know my liver was tired and overburdened. I, in no way, understood my constant fatigue and vague lack of vitality. After doing more research, I discovered this powerhouse, old school herb and life has never been the same. I am NOT being melodramatic.

How to Use Yellow Dock


Looks Like Coffee, or Kawi Iyusdi (Yellow Dock) is not only a medicinal herb, but also a food. It is much like spinach, but actually contains more vitamins and minerals. Because of the long taproot, it gathers nutrients from deep underground. The leaves are a source of iron, and also have laxative properties. Juices from the stems, prepared in a decoction, can be made into an ointment with beeswax and olive oil, and used for itching, minor sores, diaper rash, and other irritations. Cherokee herbalists prescribe a warm wash made from the decoction of crushed roots for a disinfectant. Juice from the root, not prepared in any certain way, is said to be a cure for ringworm. [1]


I think, as our pallets have become “softer” that dock is a bit coarse for most peoples’ taste, but I tried them in the spring when the leaves are young and tender and they are quite delicious as a green and unusually delicious as a tea.

Dock, locally known as “Curly Dock” is used in the spring as a potherb. The greens, picked young, provide an interesting sour tasting cooked green that is very nutritious. It is in the Buckwheat family and grows in waste places, old fields and barnyards and generally considered a “weed”, I know that’s what I called it when it was growing where I wanted to plant green beans. I pulled so many roots that year! And not in a good way. After I realized, year later, what I’d done I was mortified. Today, this root is one that I value very highly.

Yellow Dock nourishes healthy blood in two important ways – it helps keep it clean and free of impurities, and supplies it with vital iron. In fact, Yellow Dock contains more iron than any other plant. It also contains varying amounts of phosphorus, vitamins A and C, and calcium.


To date, I have found no cosmetic use for Dock.

Properties of Yellow Dock

Rumicin is the active principle of the Yellow Dock, found in the roots.

The medicinal root is one that, as I mentioned, I value very highly. Therefore, this seeming weed now now has a permanent residence at Our Herb Farm where it is given the attention it deserves.

It is commonly used for acute and chronic inflammation of the nasal passages, throat, and respiratory tract, as well as for wounds and abrasions, gum problems, and headache.

  • anthraquinones (up to 4% nepodin, emodin, chrysaphanol, and physcion)
  • tannins
  • oxylates
  • volatile oil
  • vitamins (A, B, and C)
  • minerals (especially manganese, phosphorus, calcium, iron, magnesium, and selenium)

Traditionally Dock was used for stomach and liver ailments and to purify the blood. The root is said to be an effective treatment for post-hepatitis flareups. It stimulates the flow of bile, which enhances digestion and ridding the body of toxic wastes. Such cleansing is used to treat a number of conditions marked by stagnant toxins in the body including acne, boils, eczema, psoriasis, fungal infections, sluggish digestion, constipation, arthritic and rheumatic conditions. It also holds potential as a long-term treatment for chronic disease, especially that of the gastrointestinal tract. It is very helpful for improving integrity of the walls of the small intestine.

Yellow dock root is an herb that supports health as a digestive tonic, acting specifically on the liver, gall bladder, and kidneys to improve function and cleanse. Yellow dock root assists protein and fat digestion, assimilation of A, B12, and E, and is indicated for poor iron absorption. It is effective at relieving constipation, inflammation in the colon, and jaundice when these symptoms are in direct relation to assimilation and digestive issues.

Short term use of decoctions internally, not only relieve constipation, but are also used for boils by mixing an equal amount of yellow dock, burdock, and red clover.

Like dandelion and burdock roots, yellow dock roots and preparations are used to improve conditions related to a sluggish digestive system, such as liver dysfunction, acne, headaches, and constipation. Because it improves absorption of nutrients, yellow dock is used to improve anemia and poor hair, fingernail, and skin quality.

Used along with other herbs, it is an antibacterial adjuvant.

Dose: 1 teaspoon of dried root in 8 ounces water, decoct for 10-15 minutes, let steep 30 minutes, take 4 ounces 2-3x/day; 1-2 mL of a 1:5 tincture 3x/day


  • Despite its gentle laxative effect, yellow dock has not been found to stimulate the pregnant uterus (Romm, 2010).
