Prepared from the mustard seed, mustard oil is a versatile oil that can be used for both therapeutic uses and culinary applications. As one of the more common types of seed found in the Mediterranean, mustard seeds produce an oil that is both aromatic and soothing to the skin. Mustard oil also lends itself well to infusion with other herbs and spices, making it possible to produce a number of oils that are ideal for cold dressings as well as cooking.
When it comes to the use of oils as a soothing topical agent, mustard oil is considered to be helpful with the pain and discomfort associated with arthritis. Along with leaving relatively little residue, mustard oil provides a pleasant aroma that may also appeal to the user of the oil. The use of mustard oil as an ointment for stiff joints has a long history, and is still recommended by persons who prefer to use natural agents to treat various health ailments.
