Brief Summary:
The researchers investigated the anti-diabetic effects of Allium hookeri root extract for Korean prediabetic participants.

Condition or disease Intervention/treatment Phase
PreDiabetes Dietary Supplement: Allium hookeri extract Dietary Supplement: Placebo Not Applicable

Detailed Description:
Allium hookeri root is widely consumed as a vegetable and herbal medicine in Asia. Although the antidiabetic activities of Allium hookeri have been documented in animal studies, the improved effects of Allium hookeri on human are not clear. Therefore, in this study, the researchers investigated whether Allium hookeri root extract could be effective in reducing the risk of type 2 diabetes in individuals with prediabetes.
