Black Mustard Healing Properties

The entire plant contains a glycoside (sinigrin), which, using an enzyme, micronase, becomes an essential sulfur oil with revulsive solid properties. Its seeds also contain mucilage with emollient (soothing) properties.

Mustard flour is mainly used in external applications. As a revulsive substance, it attracts blood towards the skin, thus reducing the congestion of internal organs and tissues. When utilized in poultices, it effectively treats rheumatism, sciatic, neuralgia, lung congestion, and acute bronchitis.

Foot baths with mustard flour are a remedy that has been used for a very long time with two main applications:

• Headaches—Foot baths alleviate headaches by attracting blood to the feet and reducing congestion in the head. They are especially recommended for cephalalgia caused by a viral infection of the upper respiratory airways (nasal catarrh, sinusitis, influenza) or high blood pressure.
• High blood pressure: Mustard produces peripheral vasodilation (dilating small arteries on the extremities), which decreases blood pressure.

Traditional foot baths with mustard flour are still highly desirable because they are effective for headaches, primarily when colds, influenza, and sinusitis cause them. Foot baths are also helpful for high blood pressure.

Warning

Mustard is an irritant seasoning that should be avoided orally. People suffering from dyspepsia or gastro-duodenal ulcers should completely abstain from mustard.

Other Mustard Species

Besides black mustard, there are two other species.

• White mustard (Sinapsis alba L.), which produces more giant, whitish seeds, makes edible mustard (seasoning).
• Wild mustard (Brassica kaber Wheeler = Brassica arvensis Rabenh. = Sinapsis arvensis L.) has tiny seeds.

Though less intense, both mustard species have similar properties to black mustard.

How to use Black Mustard

1. Poultices—Mustard flour is applied as hot poultices and mixed with linseed flour to be less irritant. These poultices are applied twice daily for 10 to 15 minutes (a prolonged application can produce blisters). Mustard poultices are called sinapisms (a word from the Greek synapsis mustard: see one of its scientific names).
2. Foot baths: Dissolve 1 to 2 spoonfuls of mustard flour in 2 to 3 liters of hot water. Take 2 to 3 baths daily, for 5 to 10 minutes each.
