Can a Tea Really Cleanse Your Arteries? Natural Ways to Support Heart Health

Clogged arteries are a serious concern for many Americans, so claims like Barbara O’Neill’s that a specific tea can “cleanse your arteries” and was “hidden by Big Pharma” spark hope among health-conscious individuals. The idea of a simple, natural drink protecting your heart is exciting, but such bold promises need careful scrutiny to ensure they’re safe and grounded in reality. While no tea can instantly clear arteries, certain beverages and lifestyle habits can support cardiovascular health over time. Let’s explore what science says about artery health, examine O’Neill’s claims, and share practical, evidence-based tips to nurture your heart, using trusted sources like Harvard Health and the Mayo Clinic.

Why Artery Health Matters

Your arteries carry oxygen-rich blood to your heart and body, but when plaque—made of cholesterol, fat, and calcium—builds up, it narrows them, raising risks for heart disease, the leading cause of death in the U.S., per the CDC. About 18 million Americans have coronary artery disease, often linked to diet, inactivity, or smoking, per the American Heart Association. Barbara O’Neill, banned in 2019 by the New South Wales Health Care Complaints Commission for unproven health advice, claimed in videos like “This Tea Cleanses Your Arteries: Pharma Hid This From You!” that a tea can rapidly clear plaque, per YouTube content. Her claims, often amplified on platforms like X, lack peer-reviewed support, but heart health is critical, making it worth exploring safe strategies.

What Causes Clogged Arteries?

  • Poor diet: High saturated fats, sugars, and processed foods promote plaque buildup, per Harvard Health.
  • Inactivity: Lack of exercise reduces blood flow and HDL (good) cholesterol, per a 2020 study in Circulation.
  • Smoking: Tobacco damages artery walls, accelerating plaque formation, per WebMD.
  • High cholesterol: Elevated LDL (bad) cholesterol deposits in arteries, per the Mayo Clinic.
  • Stress: Chronic stress raises blood pressure, straining arteries, per Cleveland Clinic.

Symptoms like chest discomfort or shortness of breath may signal artery issues, but many cases are silent until advanced, requiring lifestyle changes or medical care to manage risks.

O’Neill’s Claimed Tea

O’Neill’s video doesn’t specify the exact tea, but her talks often promote green tea, hibiscus tea, or herbal blends like hawthorn for heart health, per sources like coconote.app and healthyline.com. She suggests these teas dissolve plaque and were suppressed by pharmaceutical companies, but no studies confirm a tea can “cleanse” arteries, per the NIH. Green tea, a likely candidate due to its antioxidant content, is a common focus in her advice. Let’s examine green tea and other beverages for their potential to support heart health.

Green Tea for Cardiovascular Support

Green tea contains catechins, antioxidants that may reduce LDL cholesterol oxidation, a factor in plaque buildup, per a 2018 study in the Journal of the American College of Nutrition.

  • Potential benefit: May lower LDL cholesterol and improve artery function, per Harvard Health.
  • How to use: Drink 1–2 cups of green tea (1 tsp leaves in 8 oz hot water) daily.
  • What to expect: Gradual improvements in cholesterol levels over weeks to months.
  • Caution: Limit caffeine if sensitive, as it may raise blood pressure; consult a doctor, per WebMD.

Other Drinks That May Support Heart Health

While no tea “cleanses” arteries, certain beverages can promote cardiovascular wellness when paired with a healthy lifestyle. Below are three additional science-backed options, based on insights from WebMD, Cleveland Clinic, and recent studies.

Hibiscus Tea

Hibiscus tea contains anthocyanins, which may lower blood pressure and cholesterol, per a 2019 study in Nutrients.

  • Potential benefit: Supports heart health by reducing hypertension, per Harvard Health.
  • How to use: Steep 1 tsp dried hibiscus flowers in 8 oz hot water for 5–10 minutes, drink 1–2 cups daily.
  • What to expect: Slight blood pressure reduction over weeks with consistent use.
  • Caution: May interact with blood pressure medications; consult a doctor, per Cleveland Clinic.

Pomegranate Juice

Pomegranate juice is rich in polyphenols, which may improve artery function and reduce plaque buildup, per a 2020 study in the Journal of Agricultural and Food Chemistry.

  • Potential benefit: Enhances blood flow and reduces oxidative stress, per WebMD.
  • How to use: Drink 4–8 oz of 100% pomegranate juice daily, diluted with water to reduce sugar.
  • What to expect: Subtle cardiovascular support over months.
  • Caution: High sugar content; limit portions and check with a doctor if on statins, per the Mayo Clinic.

Water with Lemon

Staying hydrated supports blood flow, and lemon adds vitamin C, which may reduce inflammation, per a 2019 study in Nutrients.

  • Potential benefit: Promotes hydration and mild anti-inflammatory effects, per Healthline.
  • How to use: Squeeze half a lemon into 8 oz water, drink 1–2 glasses daily.
  • What to expect: Improved hydration and circulation within days.
  • Caution: Avoid overconsumption to protect tooth enamel, per WebMD.

Debunking O’Neill’s “Cleanse Arteries” Claim

O’Neill’s claim that a tea can “cleanse” arteries and was hidden by Big Pharma lacks scientific evidence, per the NIH. Arterial plaque builds up over years and cannot be reversed quickly; severe cases require medical interventions like statins or surgery, per the Mayo Clinic. Her history of unverified advice, including dangerous cancer claims, led to a lifetime ban in Australia, per The Guardian. A 2025 X post from @HealthVibes2023 echoed her claim about a “secret” artery-cleansing tea, but no studies support rapid plaque removal, per Harvard Health. Drinks like green tea or hibiscus may support heart health, but effects are gradual and depend on lifestyle, per WebMD.

Realistic Expectations

  • Within 7 days: Possible mild improvements in energy or blood pressure with hydration and low-sugar drinks.
  • Long-term use: Reduced cholesterol, better blood flow, and lower heart disease risk with sustained healthy habits over months.
  • No quick cleanse: Arterial plaque requires medical management, not teas alone, per Cleveland Clinic.

Practical Tips to Support Heart Health Naturally

To nurture your arteries and overall heart health, combine a balanced diet with lifestyle changes. Here are evidence-based tips from Harvard Health and WebMD to promote cardiovascular wellness:

  • Eat a heart-healthy diet: Include fruits, vegetables, whole grains, and lean proteins to reduce cholesterol, per a 2020 study in Circulation.
  • Stay active: Aim for 150 minutes of moderate exercise weekly, like brisk walking, to improve HDL cholesterol, per the CDC.
  • Limit saturated fats: Keep saturated fats to less than 10% of daily calories, choosing olive oil over butter, per the American Heart Association.
  • Manage stress: Practice 5–10 minutes of meditation or deep breathing daily to lower blood pressure, per Cleveland Clinic.
  • Quit smoking: Stop smoking to reduce artery damage, with benefits starting within weeks, per the Mayo Clinic.

Heart-Healthy Foods and Drinks

  • Green tea: 1–2 cups daily for antioxidants, per Harvard Health.
  • Hibiscus tea: 1 cup daily to support blood pressure, per WebMD.
  • Pomegranate juice: 4 oz diluted daily for polyphenols, per Cleveland Clinic.
  • Berries: ½–1 cup daily for anti-inflammatory flavonoids, per Healthline.
  • Salmon: 2–3 servings weekly for omega-3s, per the Mayo Clinic.

Risks of Unverified Heart Health Claims

O’Neill’s claims, like those on X suggesting a tea cleanses arteries and was hidden by Big Pharma, lack evidence and may mislead, per The Guardian. Potential risks include:

  • False hope: Exaggerated promises can disappoint and discourage effective strategies, per Harvard Health.
  • Delayed treatment: Relying on teas may postpone medications or procedures for heart disease, per the Mayo Clinic.
  • Medication interactions: Hibiscus or pomegranate may affect drugs like statins, per WebMD.
  • Misinformation spread: AI-generated content and fake ads exploit O’Neill’s name, per The Guardian.

Consult a doctor before trying new remedies, especially if you have heart conditions or take medications, per WebMD.

When to Seek Professional Help

If you experience chest discomfort, shortness of breath, or irregular heartbeats, seek medical attention immediately, as these may signal heart disease, per the Mayo Clinic. Those with high cholesterol, hypertension, or a family history of heart issues are at higher risk, per Harvard Health. A doctor can order tests (e.g., lipid panel) and recommend treatments like statins or lifestyle changes, per WebMD. Avoid unproven remedies, like O’Neill’s, that may delay care, per The Guardian.
