Elderberry as a Blood Thinner?
Elderberry is a popular natural remedy known for its impressive health benefits, especially for immune support. But you might have heard whispers about elderberry as a blood thinner. Is there any truth to this claim?
While some evidence suggests that elderflower (the flower of the elderberry plant) may have mild blood-thinning properties, the effects are generally considered insignificant. There haven’t been any major scientific studies to thoroughly investigate the blood-thinning potential of elderberry.
Therefore, it’s not recommended to use elderberry as a blood thinner in place of conventional medications. However, elderberry can still offer valuable support for cardiovascular health. [1]

Elderberry's Cardiovascular Benefits
Even though it might not be a potent blood thinner, elderberry has several potential benefits for your heart and circulatory system:
- Improved Blood Circulation: Elderberry has been traditionally used to improve blood circulation, particularly in the peripheral areas like the hands, feet, and skin [2]. It can help alleviate symptoms like blueish extremities and pale skin, promoting a healthy appearance.
- Cholesterol Management: Some clinical trials suggest that elderberry may help reduce cholesterol buildup in blood vessels, although more research is needed to confirm this effect [3].
- Blood Sugar Regulation: Elderberry can help manage blood sugar levels by inhibiting alpha-glucosidase, an enzyme that breaks down dietary starches into glucose [4]. This, combined with its potential to increase insulin production, makes elderberry a valuable tool for managing diabetes and prediabetes, conditions often linked to heart disease.
- Uric Acid Reduction: Elderberry can help lower uric acid levels in the blood [5]. Uric acid plays a role in blood pressure regulation, and reducing its levels may have positive effects on cardiovascular health.
Important Considerations for Elderberry Use
- Consult Your Doctor: While the potential cardiovascular benefits of elderberry as a blood thinner are intriguing, it’s crucial to consult your doctor before using it, especially if you’re taking medications or have underlying health conditions.
- Dosage and Preparation: Elderberry is available in various forms, including syrups, capsules, and teas. Follow recommended dosage guidelines and avoid consuming raw elderberries, as they can cause nausea.
Beyond Blood Thinning: Elderberry's Nutritional Powerhouse
In addition to its potential cardiovascular benefits, elderberry is a nutritional powerhouse, packed with:
- Vitamin C: A potent antioxidant that supports immune function.
- Anthocyanins: Antioxidant and anti-inflammatory compounds that give elderberries their dark color.
- Flavonoids: Another group of antioxidants with various health benefits.
- Phenolic Acids: Antioxidants that contribute to elderberry’s protective effects.
Embrace the Power of Elderberry - Not as a Blood Thinner!
While the blood-thinning properties of elderberry are still under investigation, its potential benefits for cardiovascular health and overall well-being are undeniable. Incorporate elderberry into your diet responsibly and enjoy its many health-promoting properties.
