Core Tip

Core Tip: Allium sativum (garlic) demonstrates significant potential in managing type 2 diabetes mellitus through its immunomodulatory effects, primarily due to its organosulfur compounds like allicin. Preclinical and clinical studies suggest garlic improves metabolic control by reducing inflammation, oxidative stress, glucose levels, and insulin resistance, with benefits comparable to antidiabetic drugs. It may also positively impact complications such as metabolic-associated fatty liver disease, hypertension, nephropathy, and cardiovascular disease. However, more clinical trials are needed to confirm its therapeutic efficacy and optimize its use in type 2 diabetes mellitus treatment. Garlic offers promise as a natural adjunct to conventional diabetes management.
