Unani Medicine Uncovered: Core Concepts And Quality Evaluations
Abstract: Unani medicine, a traditional healing system primarily reliant on herbal remedies, finds its roots in the ancient wisdom of Greek philosopher Hippocrates (460–377 BC) and his associates. Its evolution and prominence, however, owe much to the support of Persian and Arab empires before making its way to the Indian subcontinent around the mid-14th century. Unani practitioners believe that each individual possesses a unique temperament shaped by the interplay of four …
