Black Mustard is commonly seen growing along pathways, in parks and across abandoned building sites cross London and most major cities in the U.K.
It is a hardy annual with lobed leaves and small, four-petalled yellow flowers. Each flower is replaced by a slender pod that divides in two parts when the plant is ready to disperse its seeds.
Black Mustard seeds are used to make one of the world’s most popular spices. The seeds, which can be a skin irritant, also have antibacterial properties and are traditionally used to treat rheumatism.

- Mustard essential oil has had several positive responses with in vivo experiments against cancer3, 4, 5, 6
- A diet with whole grains and mustard oil has been related to a reduction of risk factors for coronary heart disease, angina pectoris and cardiac arrhythmias7 (clinical trial)
- In experiments, the whole plant or mucilaginous extract showed a reduction of diabetes symptoms, 8,9,10 (in vivo)
- Other properties of black mustard include its positive effects on healing cuts and wounds11 (in vivo)
How it can be used
