Medicinal Plants
The hibiscus flowers you might grow for tea and the olive tree in a Mediterranean-style garden both show up in this review as having measurable effects on blood pressure and artery health.
Scientists pulled together over 150 studies on heart disease and noticed that a handful of familiar plants keep showing up as helpful: astragalus root, bergamot citrus, hibiscus flowers, and olive leaves. These plants seem to calm inflammation and oxidative stress in blood vessels, the same processes that drive artery clogging and high blood pressure. It's not a replacement for medication, but it adds weight to why these plants are worth having in an edible or medicinal garden.
Key Findings
Global cardiovascular disease prevalence nearly doubled between 1990 and 2019, with mortality still climbing.
Astragalus membranaceus, Citrus bergamia (bergamot), Hibiscus sabdariffa, and Olea europaea (olive) showed cardioprotective effects across the reviewed literature.
156 articles were selected from roughly 300 screened, with 85% published between 2020 and 2025, alongside emerging drug therapies like PCSK9 inhibitors and SGLT1/2 inhibitors.

A review of heart disease research highlights that certain medicinal plants, including astragalus, bergamot, hibiscus, and olive leaf, show real promise for protecting the heart and blood vessels alongside modern drug treatments.
