It is a condition that happens due to the inability of the body to regulate and use simple sugar (glucose) as fuel or source of energy to the body and would later lead to an increase in blood sugar level. Citrus hystrix or also known as Kaffir lime, is one of the most common citrus fruits in the Southeast Asian region that is known to have an antidiabetic potential. Consequently, this research aims to investigate the usage of Kaffir lime as a natural as well as Halalan Thayyiban antidiabetic alternatives for patients suffering from Type II Diabetes in lowering their blood sugar content. In Brunei Darussalam, most cases of DM are related to Type II Diabetes. This can be caused by the unhealthy lifestyle and unbalanced diet of many of the local citizens which are already suffering from overweight and obesity. This study has been reviewing secondary data such as books, journals and articles of other researchers of the same or similar field of research or topic as a source of reference and data collection. The findings show that Kaffir lime can be a good source of antidiabetic alternatives for diabetic patients as it is naturally occurred and Halalan Thayyiban. The phytochemical contents of the Kaffir lime which include such as flavonoids is proved to have an effective impact towards inhibiting the activity of alpha-amylase enzyme, an enzyme that catalyses the digestion of starch into simple sugars such as glucose. This could help diabetic patients to regulate their blood glucose levels accordingly with the correct amount of Kaffir lime extract intake.</jats:p>en-USHalalanThayyibanNaturalAntidiabeticAlpha-Amylasejournal-article113303
