Burdock, Arctium lappa and Arctium minus

Arctium lappa and Arctium minus are similar in appearance. The two have similar medicinal properties. Arctium minus is more widespread.

Range and Identification of Burdock Plants

Native to Asia and Europe, burdock has naturalized around the world. It's found throughout most of the United States and North America, except Florida and the extreme northern parts of the continent (see map).

Burdock thrives in moderately disturbed areas such as barnyards, field edges, fence rows, railroad tracks, roadsides, along paths and sometimes along the edges of woodlands or streams. Animals carry the seeds in their fur or feathers, distributing them far and wide.

As a biennial, the plant takes two years to complete its growth cycle. This means that it must be relatively undisturbed during this time. Thus, the growth along edges of fields and crop lands, etc. Under certain growing conditions, plants stay in a rosette for two years and don't bloom until year three, so wild burdock plants may be a mix of ages.

Burdock Leaves and Flowers

During the first year of growth, the plant forms a basal rosette with 2-5 large, wedge shaped leaves up to 28 inches (70 cm) long and 14 inches (36 cm) wide. They resemble rhubarb at a glance, but rhubarb leaves are glossy, while burdock leaves are matte and somewhat fuzzy on the underside.

During the second year of growth, plants produce a large flower stalk, reaching up to 6  1/2 feet (2 m) tall. (These plants tend to be very easy to spot.)  Mine usually stand about 4-5 feet tall.

Flowers are small and emerge from the tops of green, prickly balls. The fragrance is sweet, if you can get close enough to take a whiff. They are pink in color, and resemble the flowers of bull thistles.

Arctium minus flowers are shown below.

Great burdock (Arctium lappa) flowers have longer pedicels, spreading clusters, and larger, rounder heads.

These flower heads dry into little brown prickly balls that stick to everything, inspiring the invention of velcro fasteners.

What does burdock taste like?

The above ground parts of burdock have a very bitter coating. Once you get past that, the flavor of the flower stalks and leaf petioles is mellow. The roots are the tastiest, with a flavor somewhat like parsnip, but less sweet.

Don't try to eat the leaves. In The Forager's Harvest, Samuel Thayer states (with respect to eating the leaves after cooking them in several changes of water), “Perhaps there is some semantic loophole by which such horrific greens can be admitted to the edible classification…”

NOTE: Burdock can accumulate toxins from the environment, so always forage from uncontaminated areas to use the plant for food or medicine.

What parts of burdock are edible?

Edible burdock parts include the petioles (leaf stems), flower stalks and roots. Remove the outer covering of petioles and stalks before cooking, as they are very bitter.

Burdock nutrients include phosphorous, potassium, sodium and large amounts of chromium, magnesium, silicon, zinc and iron. The seeds contain vitamins A, C, thiamine and riboflavin.

Stalks

Samuel Thayer says cooked burdock stalks are superb. “When steamed or boiled for a long time they become very soft like new potatoes; they are starchy and not at all fibrous like the roots or petioles. I like to serve them alone as a vegetable dish, and their mild, slightly sweet flavor can't go wrong in soup or stir fry. When burdock stalks are in season (late spring to early summer, when the shoot are 1-3 feet tall and not yet stiff), they are a truly fine vegetable.”

Healing Wise (Wise Woman Herbal Series) Healing Wise gives full instructions for harvesting and storing the plant parts, and using them medicinally, as well as a number of recipes including “Chicken Fried Burdock Stalks” and “Japanese Sweet and Sour Gobo”.

Susun Weed recommends prepping your stalk by removing the skins, chopping to size, and then soaking for 15 minutes in cold water with a splash of vinegar. She then boils for 10 minutes, strains, and boils with fresh water for another 10 minutes, or until tender. I tried out her “chicken fried burdock stalks”, and they weren't half bad.

Roots

Fresh burdock root is good in stir fry, and tastes fairly mild raw – crisp and a bit sweet. Collect roots any time from mid summer to late fall, or in spring before the plants put up a flower stalk. Once the plant shoots up a stalk, energy stored in the root goes to produce the flowers, and the roots get tough and tasteless.

If you really want to try “gobo” root, you may want to plant some seeds in deeply cultivated, well mulched soil. Digging roots in rough ground is a major undertaking – they grow really deep.

Burdock Benefits

Several of my favorite wildcrafting books rave about burdock. Susun Weed loves burdock, and goes on at length about it in Healing Wise. She recommends all parts of the burdock – roots, seeds and leaves. There's even talk of burdock as an aphrodisiac.

Backyard Medicine gives instructions for burdock leaf poultice, burdock root extract (decoction) and burdock and dandelion toffee. To make a poultice, simple steam the leaf and apply it hot to the affected area to speed healing. Cover with a hot pack or hot water to trap the heat and leave on for about 30 minutes. Try this on sore muscles or skin damage.

Brew burdock root tea as a decoction, boiling the roots for around 20 minutes to release the active compounds. A combination of burdock root and dandelion root is excellent for detoxifying.

Diuretic and Laxative

Both burdock roots and seeds are used as a diuretic, helping to remove excess water from the body. Edema (abnormal fluid retention) is a common problem with many people as they age and/or are less active.

The seeds act as a laxative, making them useful for constipation. Burdock root contains inulin (insoluble fiber) and mucilage, bulking and softening stool for easier passage. (Note – excess inulin may cause gas. Start with a small portion if consuming burdock root for the first time.)

Regulates Blood Sugar

Burdock root has a long history of use to lower blood sugar in diabetics. A 2014 study looked at the antihyperglycemic potential of dried burdock root extract, and found evidence of improved glucose tolerance. It is listed under Herbal Remedies for Diabetes in the International Journal of Biomedical and Advance Research.

Fights Infection

Burdock root has antifungal and antimicrobial properties, and has been shown to act against gram negative bacteria, like E. coli. (source) The sesquiterpene lactone found in the leaves acts against gram positive bacteria, such as Staphylococcus aureus.

Treats Skin Conditions

Used internally or externally, burdock may help with skin conditions. Burdock seed tincture is often applied to the skin or taken internally for acne.

Burdock root tea and tincture, especially in combination with dandelion, helps to clear toxins, and may help with conditions such as psoriasis and eczema.

May Inhibit Cancer

Historically used by the Potawotami Indians for treating cancer, burdock is also one of the four herbs used in Rene Caisse's Essiac® tea and the Hoxsey Formula. A 2016 study found benefit to the use of burdock seed extract in bladder cancer treatment.

Possible Side Effects or Allergic Reactions

Although burdock is generally considered safe, there are a few possible side effects of Arctium lappa and A. minus:

  • Burdock is a natural diuretic, so it may impact the use of other diuretics and prescription medication. Always check with your health care provider before using herbal supplements if you are on prescription medication.
  • Because of its ability to lower blood sugar, burdock may impact the use of insulin for people with diabetes.
  • The bitter compounds on the leaves and stems may cause mild contact dermatitis to sensitive individuals.
  • If you are allergic to plants in the daisy family, be cautious with the use of burdock. It is in the same family (Asteraceae), so it's possible tat it might cause an allergic reaction in sensitive individuals.
  • Burdock may act as a uterine stimulant, so avoid use during pregnancy.

Wildlife Uses

Illinois Wildflowers lists the animal uses of burdock (faunal associations):

Burdock flowers attract long-tongued bees, including bumblebees, honeybees, Miner bees, and Leaf-Cutting bees. Other visitors include bee flies, butterflies, and skippers, which seek nectar and are also effective at pollination.

The caterpillars of several moth species bore through the stems, and painted lady butterfly caterpillars (Vanessa cardui) eat the leaves. Ring necked pheasants eat some burdock seeds, but they're not a primary food source.

Burdock's butter taste keeps most mammals away, although livestock and deer will eat it if they have little else. The foliage may be toxic to rabbits.

Burdock Removal and Control

If burdock is taking over your pasture, it may be time for some soil testing. The plants like soil that's high in iron and low in calcium. Sometimes adding lime or gypsum may help.

Burdock only reproduces by seed, so  clear plants before the seed matures (or burn the dried seed heads) to reduce the spread. Regular mowing and cultivation will knock the plants back, but the roots go deep. Healing the soil and planting ground cover to crowd the burdock out is your best bet for long term control.

Other Common Names

Burdock is also known as gobo, niu bang zi (traditional Chinese medicine), bardana, Love's leaves, beggar's buttons, cockle buttons, thorny burr, burr seed, clotbur, cocklebur, grass burdock, stickers, stick tight, burs, burrseed, cuckcoo button, cloth burr, clorbur, fox's clote hardock, hareburr, hurrburr, turkey burrseed, turkey burr, personata, bat weed, wooly dock, happy major, prosopium, philanthropium, and many other names around the world.

  1. Hey Laurie – I have a new name for you to add to this list of names for burdock. “Chicken Pokers”! Let me explain. Our youngest daughter was trying to remember the name because our dog got into a patch and obviously got covered in the darn things. Abby was trying to tell me what was the matter with the dog. She thought they were named after a BIRD (BURDock – get it?) and she knew they were “pokey” – hence the name CHICKEN POKERS. Now you’ll be calling them chicken pokers too… 😀 Susan H.

  2. Thanks for these “weed” posts – I am pretty sure i have seen these in Ontario and maybe Saskatchewan – not here in Newfoundland yet but they may be here all the same. Am trying to identify some wild plants here but a lot of people don’t know the names of them. These articles and others are a great help!

    1. You’re welcome, Lois, and thanks for taking time to comment.

      I stopped doing the series before because the posts never got much traffic, but I think I have a better understanding now of what people are searching on and as I’m redoing them, they’re finally starting to get some traffic.

      Weeds are patient. The seeds can wait for years, even decades, in the soil to sprout and grow. If we learn to understand what they are telling us and how to use them instead of just trying to kill them all, I think we would be much better off.

  3. Great information for local weeds, who would of known how many things it makes the body better, wow

  4. Learning how to control them or that they even had a use, would have been really useful 20+ years when I was living in rural Utah. That could have saved my family and my Mom’s cocker spaniel’s a lot of trouble, pain, and a lot of money on new tights (the family, not the cocker spaniels, lol). We called them cocklebur and boy did they get imbedded into the coats of my Mom’s prized cocker spaniels and even our horses manes and tails.
    I appreciate you putting this information out there, even if it was years ago. I found your site and this series because I’m trying to find what local “weeds” I can use to feed to my bearded dragon that also have medicinal purposes. I first came across your “Grandma’s medicine weed” post (broadleaf plantain is great for bearded dragons on occasion if anyone is curious/interested) and now I’m working my way through the rest.
    Thanks again for leaving this information available throughout the years.

    1. You’re welcome, Lisa.

      Our cat, Big Fluffy, always manages to find any burdocks on the property and I’ve spent a good amount of time working them out of his fur. We give him a modified lion cut for summer to reduce the issue, but he still gets them in his mane and tail. We don’t have a ton of them and I use them for food and medicine, so it’s only a minor hassle, but I’ve seen pastures that were completely taken over and that would be a real problem.

      I’m slowly working through updating the posts, adding more information and photos.

      Good on you for researching wild edibles. I don’t believe I have info specifically related to bearded dragons, but there is general edibility info on almost every entry.
