The anti-inflammatory properties of mustard oil make it effective for relieving the condition of irritable bowel syndrome by reducing inflammation in the lining of the stomach. A massage with mustard oil helps relieve rheumatic and arthritic pain as well as soothes sprained ankles and other joint aches and pains. Its anti-inflammatory properties can be attributed to the presence of trace mineral called selenium that is good for relieving joint and skin inflammation. In case of arthritic pain, heat 3 to 4 garlic cloves in 2 tablespoons of mustard oil and rub it on sore joints for relief. However, in case of burning or tingling sensation or appearance of rashes, immediately stop using this oil.
