The root has been used medicinally for centuries to treat arthritis, asthma, and epilepsy. Black turmeric root is crushed and can be applied to bruises and sprains to ease discomfort or applied to the forehead to help relieve symptoms of migraines.
The turmeric can also be used in fever, joint pain, skin disorder, respiratory disorders, dyspepsia, vomiting, abdominal cramp and cough, among others.
