7. Mustard Oil

Mustard oil boosts blood circulation, which can ease pain and swelling around the knees. Though not safe for direct eating in some forms, mustard oil is excellent for massages. Warming it slightly and applying it to sore areas can provide immediate comfort. Some recipes also use mustard essential oil for cooking, adding flavor and healing benefits. It's an old-school remedy that still works wonders for relieving knee pain naturally.
