Young leaves - raw or cooked as a potherb or as a flavouring in cooked foods[4, 5, 9, 12, 62, 115, 244]. A mild garlic and mustard flavour, the leaves are also believed to strengthen the digestive system[244]. They can be finely chopped and added to salads[7, 183]. The leaves are available very early in the year and provide a very acceptable flavouring for salads in the winter[K]. Flowers and young seed pods - raw[62]. A mild, garlic-like flavour[K].

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Antiasthmatic  Antiscorbutic  Antiseptic  Deobstruent  Diaphoretic  Eczema  Sternutatory  Vermifuge  
Vulnerary

Garlic mustard has been little used in herbal medicine[268]. The leaves and stems are antiasthmatic, antiscorbutic, antiseptic, deobstruent, diaphoretic, vermifuge and vulnerary[4, 7]. The leaves have been taken internally to promote sweating and to treat bronchitis, asthma and eczema[4]. Externally, they have been used as an antiseptic poultice on ulcers etc[4], and are effective in relieving the itching caused by bites and stings[244]. The leaves and stems are harvested before the plant comes into flower and they can be dried for later use[238]. The roots are chopped up small and then heated in oil to make an ointment to rub on the chest in order to bring relief from bronchitis[245]. The juice of the plant has an inhibitory effect on Bacillus pyocyaneum and on gram-negative bacteria of the typhoid-paratyphoid-enteritis group[240]. The seeds have been used as a snuff to excite sneezing[4].

Cultivation details

Prefers a damp rich alluvial soil[7, 53]. Succeeds in damp shady places where few other herbs will grow[238]. A good woodland edge plant, it also grows well in the bottom of hedgerows[24] and will self-sow freely in suitable conditions[238]. On a calm day the plant emits a strong smell of garlic. This is especially pronounced if the leaves are bruised[245]. This species is an important food source for the orange-tip butterfly[238]. In garden design, as well as the above-ground architecture of a plant, root structure considerations help in choosing plants that work together for their optimal soil requirements including nutrients and water. The root pattern is a tap root.

the leaves taste REALLY good

This plant is highly invasive in the united states and should not be propogated there. It is highly allelopathic.

My cat just stole my sample of this plant, ran off with it, and chewed it up. She loved it.

Should not be spread in the southern reaches of Canada, from coast to coast.

Garlic mustard is one of the most invasive exotics I have ever seen. (Some thoughless person brought it from Europe.) If one plant is allowed to go to seed, an entire wooded area can soon be filled with garlic mustard to the exclusion of all the native plants. Here in Wisconsin our Dept. of Natural Resources warns people about this plant and various groups volunteer to pull it up in parks. The seeds stay viable for many years, however,so the same area will have to have the plants pulled up and destroyed for years before it is eradicated. Don't plant it! Shivani in WI

It seems the stems are also edible, according to a friend and the following book: Handbook of Nutrition and Food By Carolyn D. Berdanier I'd also like to add that these plants are delicious and there are loads of them around here (just north of Toronto)!

DO NOT PLANT THIS PLANT IN THE U.S. OR CANADA, but do harvest it from the wild! If we over-harvest this weed maybe it can be controlled. A word of caution, however: harvest for food only plants that you are sure have not been sprayed with a herbacide, as is done in many natural areas.

This plant, despite all the wonderful uses, is highly invasive across a great portion of the United States, and as it has been mentioned, should really not be planted as our native plants have little adaptation to successfully compete with it. However, a little scavenging will allow a collector to wind up with garbage bags full if he or she only ventures out to an appropriate habitat (woodlands, wetlands, etc...about anywhere, really!). Not only can you stock up on a decent edible, but you can help increase the population of other helpful plants by nixing some of their invasive competitors.

According to Steve Brill, the root can be used like horseradish.

@Sherrie: Thanks for the tip about the roots! Horse radish grows abundantly in my garden. I will try to pull them out and use the roots. I use the leaves in soups and salads. Delicious! Lia de Ruiter from the Netherlands.
