HIBISCUS TEA - HNTA

 A

Dr. Michael Greger discusses hibiscus tea in his book "How Not to Age" (as well as in How Not to Die and on NutritionFacts.org), praising its health benefits, especially for cardiovascular health and aging-related concerns.

Here’s a quick summary with bullet points and quotes from his take on hibiscus tea in the context of aging:


🌺 Hibiscus Tea – Key Points from “How Not to Age”

  • Powerful Antioxidant

    "Hibiscus tea is one of the highest antioxidant-rich beverages available."
    It helps combat oxidative stress, which contributes to aging and chronic diseases.

  • Blood Pressure-Lowering Effects

    "In clinical trials, hibiscus tea rivaled some antihypertensive drugs."
    Drinking 2 cups a day can significantly reduce systolic and diastolic blood pressure.

  • Anti-Inflammatory
    The anti-inflammatory properties may help slow the aging process and reduce risk of age-related conditions.

  • Liver Protection
    Some studies suggest hibiscus can support liver health, which is critical in detoxification as we age.

  • Cholesterol and Metabolic Benefits
    Modestly lowers LDL cholesterol and improves insulin sensitivity, both important in aging prevention.

  • Anti-Cancer Potential
    Preliminary research suggests hibiscus may help inhibit the growth of cancer cells, though more human studies are needed.


📝 Greger's Practical Advice

  • How to Consume:
    He often recommends 2-3 cups per day, ideally unsweetened and brewed from dried hibiscus flowers.

  • Warning:

    “Hibiscus tea can be quite potent — those on medication for blood pressure should monitor their levels.”

  • Teeth Tip:
    Because it’s acidic and can stain, drink it through a straw or rinse after drinking to protect enamel.
