Brown Mustard

A genus of about 30 species of mainly annual or biennial herbs, distributed throughout Eurasia. Mustards have provided pungent flavorings, green vegetables, and medicinal compounds from very early times. Use as a condiment in the West dates back to at least 400BCE, and medicinal uses were first mentioned in China in CE659. The Romans mixed ground seeds with grape juice; the word "mustard" derives from mustum "grape must" and ardens, "burning". Pungency of mustard develops when cold water is added to the ground seed; and enzyme (myrosin) acts on a glycoside (sinigrin) to produce the sulphur compound, allyl isothiocyanate. The reaction takes 10-15 minutes. Mixing with hot water or vinegar, or adding salt, inhibits the enzyme, producing a mild, bitter mustard. The three main kinds of commercially prepared mustard are: American, using white mustard (Sinapsis alba, see white mustard); English, using a mix of white and black (S. alba and B. nigra) or brown (B. juncea) mustards; and french, which is based on black (B. nigra) or, more usually today, on brown mustard (B. juncea). Brassica juncea has properties similar to other mustards but is used more for culinary than for medicinal purposes. It can be harvested mechanically, making it more commercially viable than B. nigra, though having only 70 percent of its pungency. Other members of the genus include cultivars of B. oleracea (cabbages, kale, Brussels sprouts, and broccoli), which have detoxicant effects and help prevent cancer when eaten regularly.

Mixing the powdered seeds of the black mustard plant with water causes the release of a volatile compound called allylisothiocyanate that is so potent it can actually blister the skin. Historically, mustard has been used to treat snakebites, treat epilepsy, ease arthritis, and increase circulation.

Annual with a much-branched stem, and lobed, roughly lyre-shaped leaves, to 16cm (6in) long. Bright yellow flowers are produced all summer, followed by small, erect, 4-angled pods with dark brown seeds.

Genus:	Brassica
Family:	Brassicacea
Native Location:	Eurasia
Cultivation:	Rich, well-drained, neutral to alkaline soil in full sun.
Propagation:	By seed sown in early spring.
Harvest:	Leaves and flowers are picked when young and used fresh. Pods are harvested as they begin to change color, and dried to complete the ripening process; this prevents the seeds frmo being shed in the field. Seeds store indefinately if kept dry. Volatile oil is distilled from seeds.
Height:	90cm-3m (3-10ft) or more
Width:	90cm-1.2m (3-4ft)
Hardiness:	Hardy
Parts Used:	Leaves and flowers, seeds, oil
Properties:	A pungent, warming herb that stimulates the circulatory and digestive systems, and irritates the skin and mucous membranes. It is a potent emetic in large doses.
Medicinal Uses:	Externally, in poultices, mustard bandages, and baths for rheumatism, muscular pain, chilblains, and respiratory tract infections. A mustard footbath is a traditional remedy for colds and headaches. Skin contact with mustard causes reddening, thus increasing blood flower and removal of toxins. Prolonged contact may result in blistering, especially in those with sensitive skin. To treat sciatica, bronchial pneumonia, sinusitis, the common cold, rheumatism, and arthritis; in footbaths to treat aching feet.
Possible Side Effects:	Black mustard can cause diarrhea, vomiting, stomach pain, difficulty breathing, and coma. Applied topically, black mustard's side effects include blistering of the skin and skin allergies.
Drug Interactions:	Taking black mustard with these drugs may interfere with the actions of the drug: Aluminum Hydroxide, (AlternaGel, Alu-Cap) Aluminum Hydroxide and Magnesium Carbonate, (Gaviscon Extra Strength, Gaviscon Liquid) Aluminum Hydroxide and Magnesium Hydroxide, (Maalox, Rulox) Aluminum Hydroxide and Magnesium Trisilicate, (Gaviscon Tablet) Aluminum Hydroxide, Magnesium Hydroxide, and Simethicone, (Maalox, Mylanta Liquid) Calcium Carbonate, (Rolaids Extra Strength, Tums) Calcium Carbonate and Magnesium Hydroxide, (Mylanta Gelcaps, Rolaids Extra Strength) Cimetidine, (Nu-Cimet, Tagamet) Esomeprazole, (Nexium) Famotidine, (Apo-Famotidine, Pepcid) Famotidine, Calcium Carbonate, and Magnesium Hydroxide, (Pepcid Complete) Lansoprazole, (Prevacid) Magaldrate and Simethicone, (Riopan Plus, Riopan Plus Double Strength) Magnesium Hydroxide, (Dulcolax Milk of Magnesia, Phillips' Milk of Magnesia) Magnesium Sulfate, (Epsom Salts) Nizatidine, (Axid, PMS-Nizatidine) Omeprazole, (Losec, Prilosec) Pantoprazole, (Pantoloc, Protonix) Rabeprazole, (Aciphex, Pariet) Ranitidine, (Alti-Ranitidine, Zantac) Sodium Bicarbonate, (Brioschi, Neut) Sucralfate, (Carafate, Sulcrate)
Disease Affects:	May worsen ulcers in the stomach or small intestines by irritating the lining of the stomach or small intestine.
Culinary Uses:	Young leaves and flowers add pungency to salads. Seeds are ground to make mustard powder or dry mustard, mixed with vinegar as a relish, and used whole in curries, pickles and sausages.
