Association of herbal tea consumption with cardiovascular diseases in the general population: evidence from the MESA cohort.
Article in Nutrition journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundGreen tea and black tea have shown beneficial effects on cardiovascular health, and they are recommended for the prevention of cardiovascular disease (CVD) events. However, the impact of herbal tea on cardiovascular health remains unclear. This study aims to evaluate the potential benefits of herbal tea consumption in reducing the risk of incident CVD events in the general population.
methodsData for this study were derived from the Multi-Ethnic Study of Atherosclerosis (MESA). The primary outcome was incident CVD events, while secondary outcomes included all-cause and cardiovascular mortality. Cox proportional hazards regression models were used to examine the relationship between herbal tea consumption and the risk of incident CVD events. Kaplan-Meier survival curves were employed to assess the timing of incident CVD events, all-cause mortality and cardiovascular mortality.
resultsA total of 4711 participants were included in the analysis, with 1834 (38.9%) in the herbal tea group and 2877 (61.1%) in the control group. Over a median follow-up of 14.1 years, 547 participants (11.61%) experienced new-onset CVD events. The herbal tea group had a significantly lower incidence of new-onset CVD events (9.0% vs. 13.3%, p < 0.001), all-cause mortality (5.1% vs. 8.8%, p < 0.001), and cardiovascular mortality (1.4% vs. 2.5%, p = 0.01) compared to the control group. Multivariate Cox regression analysis revealed that herbal tea consumption was independently associated with a lower risk of incident CVD events [HR 0.83, 95% CI (0.69–0.997), p = 0.046] and all-cause mortality [HR 0.76, 95% CI (0.60–0.97), p = 0.03]. Kaplan-Meier analysis confirmed that participants in the herbal tea group had a significantly lower risk of incident CVD events, as well as lower all-cause and cardiovascular mortality. Secondary analyses indicated that moderate frequency herbal tea consumption (2 cups/month to 2 cups/week) and consistent consumption were associated with the most pronounced cardiovascular benefits.
conclusionsThis study demonstrated that herbal tea consumption was associated with a lower risk of incident CVD events, as well as reduced all-cause and cardiovascular mortality. These benefits were especially evident among individuals who consumed herbal tea at a moderate frequency and maintained consistent intake over time.
