and insulin resistance, leading to hyperglycemia and its complications. In Unani
medicine, it is known as ziyābetus. Several drugs are prescribed in Unani medicine as single and
compound formulations for this disease. Most of these drugs have been studied on scientific
parameters and shown significant activity in reducing the symptoms and complications of diabetes.
Objectives: Critical evaluation of Unani medicines for treating diabetes patients have been
conducted. The aim of the study is to provide complete information on this subject with the action
of the mechanism so that proper treatment should be done with prospective research.
Methods: Unani literature was reviewed extensively via various search engines for the herbs,

promising actions against diabetes and its complications. In addition, none of the studies has
reported any adverse effects with the drugs. Also, there is evidence to suggest that the method of
usage described in Unani medicine may reduce or eliminate adverse events, if any. Further, there is
a great need to do more research on making medicine more effective. Besides, the review article is
useful for treating patients effectively by advancing the research.
