Group one had normal after-meal glucose and group two had high after-meal glucose.
On day one, individuals ate a standard lunch immediately after the blood draw, and then right after lunch, all were given a 250 mg capsule of clove extract.
After two hours, a post-meal glucose measurement was taken. This pattern was repeated daily for 30 days, with pre and post-meal glucose measurements taken on days 12, 24, and 30.
The results found that in those with normal fasting glucose, clove supplementation had no impact on fasting glucose (before-meal) sugar levels.
