4 min read

Historically known as the 'singer's plant,' hedge mustard has a long tradition of both culinary and medicinal applications, dating back to ancient Greek folklore where it was believed to be an antidote for all poisons. Today, these historical uses are viewed with caution due to modern safety concerns.

Quick Summary

Hedge mustard was traditionally used for throat and digestive ailments, but modern sources warn of safety risks due to potential cardiac glycosides, stressing caution and insufficient evidence for effectiveness.

Key Points

Traditional Remedy: Historically known as the "singer's plant," hedge mustard was used to treat hoarseness, coughs, and other respiratory ailments, but these claims are not supported by modern science.
Potential Cardiac Glycosides: Modern health resources, like RxList and WebMD, advise that the flowering parts are potentially unsafe to consume due to cardiac glycosides, which can harm the heart.
Edible Parts: Young leaves can be eaten raw in salads or cooked, while seeds can be used to make a mustard paste, though caution is still advised for internal use.
Crucial Identification: Correctly identifying hedge mustard is vital, as it can be confused with other plants. Foragers must be certain to avoid poisonous lookalikes.
Insufficient Evidence: There is a lack of sufficient scientific evidence to support the traditional uses of hedge mustard for conditions like bronchitis, digestive issues, and urinary tract diseases.
Prioritize Safety: Given the serious health risks associated with cardiac glycosides, it is generally not recommended to use hedge mustard as a medicinal supplement, particularly for those with heart conditions, pregnant, or breastfeeding.

A History of Traditional Use

Hedge mustard, or $Sisymbrium officinale$, is a flowering plant in the Brassicaceae family with a long and storied history in folk medicine. Historically, different parts of the plant were used to create remedies for various ailments. Though its efficacy is largely unproven by modern scientific standards, understanding its traditional applications sheds light on its cultural significance and legacy.

The "Singer's Plant" Legacy

One of the most famous traditional uses for hedge mustard is its reputation as the "singer's plant" or herbe aux chantres.

Voice Loss: For centuries, it was used to treat hoarseness and loss of voice, particularly in Europe. The juice of the plant was often prepared as a syrup with honey or sugar for this purpose.
Respiratory Issues: Beyond hoarseness, traditional herbalists used hedge mustard as an expectorant to treat respiratory infections, chronic bronchitis, wheezing, and coughing.

Digestive and Other Folk Remedies

Traditional uses for hedge mustard weren't limited to the respiratory system. It was also employed for various digestive and other issues:

Poison Antidote: The ancient Greeks and Tibetans believed it could be used to combat poisons and assist with food poisoning.
Digestive Ailments: Herbalists used it as a laxative and stomachic to treat indigestion, flatulence, and other stomach ailments.
Diuretic Properties: The plant was also valued for its diuretic properties, making it useful in treating urinary tract ailments.

Culinary Uses and Preparation

While its medicinal applications require extreme caution, hedge mustard has also been used for culinary purposes, primarily in Europe. Its leaves and seeds offer a peppery, slightly bitter flavor, similar to other mustard greens.

Leaves: Young, tender leaves can be added raw to salads, though their bitterness increases with age. Cooking the leaves, such as in a stir-fry, can help mellow the flavor.
Seeds: The small seeds of hedge mustard can be ground to create a pungent mustard paste, used as a condiment in some parts of Europe.

When foraging for any wild edible, especially one with a contentious safety profile, positive identification is critical to avoid consuming a poisonous lookalike.

Modern Perspective and Critical Safety Warnings

Despite its long history in folk medicine, modern medical sources and regulatory bodies issue significant warnings about hedge mustard, especially regarding internal consumption. Key concerns revolve around the presence of cardiac glycosides and a lack of scientific validation for its traditional uses.

Critical Safety Concerns

Cardiac Glycosides: According to WebMD and RxList, the flowering parts of hedge mustard contain cardiac glycosides, chemicals that can have serious side effects on the heart.
Risk Factors: Taking hedge mustard by mouth is potentially unsafe and can cause heart rhythm disorders, vomiting, and diarrhea. Individuals with pre-existing heart conditions, low potassium levels, pregnant or breastfeeding women should avoid it entirely.
Insufficient Evidence: Organizations like RxList classify many of the traditional medicinal claims for hedge mustard as having "insufficient evidence to rate effectiveness".

Foraging Caution

When foraging, it is imperative to be absolutely certain of the plant's identity and to be aware of its potential risks. Given the severe safety concerns surrounding internal consumption of hedge mustard, it is best to approach this plant with caution, respecting its traditional uses while prioritizing modern safety guidelines.

Hedge Mustard vs. Other Mustards: A Comparison

It is crucial to differentiate hedge mustard ($Sisymbrium officinale$) from other more commonly consumed culinary mustards like black, white, and brown mustards ($Brassica$ species). These plants are distinct, with varying safety and culinary profiles.


Feature	Hedge Mustard ($S. officinale$)	Common Mustard Greens ($B. juncea$, $B. rapa$)
Primary Use	Traditionally medicinal, wild edible	Primarily culinary (leafy vegetable)
Safety Profile	Contains potential cardiac glycosides; often advised against internal use	Generally safe to consume as food
Flavor	Peppery, often bitter; mellows when cooked	Varies from mild to pungent; common leafy green flavor
Seeds	Used traditionally for mustard paste	Used to produce popular mustard condiments
Modern Evidence	Mostly traditional use; limited scientific support; safety concerns	Well-researched for nutritional content and general safety

Conclusion: Prioritizing Safety Over Tradition

While hedge mustard has a rich history of traditional use for ailments like sore throats, coughs, and digestive issues, a modern understanding of its chemical compounds necessitates extreme caution. The presence of cardiac glycosides in the flowering plant, coupled with a lack of scientific evidence for its efficacy, means it is not a recommended herbal remedy. Its edible parts, primarily young leaves and seeds, can be used culinarily by expert foragers who are certain of their identification and are aware of the risks. Ultimately, the story of hedge mustard is a powerful example of how folk knowledge can be re-evaluated through a modern lens, prioritizing safety and scientific evidence. The key takeaway is to appreciate its historical role while heeding contemporary warnings and avoiding its use as a medicinal supplement. For authoritative safety information, consult sources like RxList, which provides detailed warnings regarding its use.
