# The Best Teas to Drink to Lower Heart Disease Risk, According to Experts
Regular tea consumption reduces cardiovascular disease risk through compounds that improve heart health. Green tea, black tea, and oolong tea contain catechins and theaflavins, polyphenols that strengthen blood vessel function and reduce inflammation, according to cardiologists and nutrition researchers studying tea's effects on the cardiovascular system.
Research published in the European Journal of Preventive Cardiology found that people drinking three cups of tea daily showed measurably better arterial flexibility compared to non-tea drinkers. The compounds in tea work by improving endothelial function, the protective lining inside blood vessels. Studies show these effects accumulate over time with consistent consumption.
Black tea offers particular benefits for blood pressure management. The theaflavins in black tea reduce oxidative stress, a key factor in hypertension. Green tea provides concentrated catechins that lower LDL cholesterol oxidation, preventing plaque buildup in arteries. Oolong tea sits between green and black tea in oxidation levels, delivering moderate amounts of both protective compounds.
Herbal teas like hibiscus show promise too. Several clinical trials demonstrate that hibiscus tea consumption lowered systolic blood pressure in people with prehypertension, rivaling some pharmaceutical interventions.
However, tea drinkers need to watch for medication interactions. Tea compounds can interact with blood thinners like warfarin, affecting how the body processes these medications. People taking statins, beta-blockers, or calcium channel blockers should consult their cardiologist about timing tea consumption, as some compounds may affect medication absorption.
Steep tea for three to five minutes to maximize polyphenol extraction. Caffeine content varies by type: green tea contains 25-50mg per cup, black tea 40-
