Mulberry leaves and water chestnut tea reduces postprandial blood glucose in borderline diabetic Japanese: A randomized, double-blind, placebo-controlled crossover study.
Trial report in Asia Pacific journal of clinical nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND AND
objectivesPostprandial hyperglycemia is a risk factor not only for diabetes mellitus, but also arteriosclerosis. Therefore, controlling the rapid postprandial increase in blood glucose levels is necessary. This study aimed to develop a mulberry leaf and water chestnut husk tea and investigate its effect on postprandial blood glucose levels. METHODS AND STUDY
designWe measured the polyphenols and 1-deoxynojirimycin contents as well as antioxidant activity of mulberry leaf and water chestnut husk tea in an in vitro experiment. The effect of the tea on postprandial blood glucose levels in 30 participants with borderline diabetes was investigated in a randomized, double-blind, placebo-controlled crossover comparison study.
resultsThe 1-deoxynojirimycin and total polyphenol contents in the tea (test food, 3g) were 10.2±0.8 and 61.3±1.4 mg, respectively. The test food showed higher antioxidant activity than the placebo food. Compared with those in the placebo group, blood glucose levels in the test group significantly decreased 30 and 60 min after eating rice. Additionally, insulin was significantly lower at all time points (30, 60, 90, and 120 min after rice consumption).
conclusionsThe mulberry leaves and water chestnut mix tea may be an effective beverage to reduce insulin secretion and prevent rapid increases in blood glucose levels in patients with borderline diabetes.
