The leaves of Vaccinium myrtillus have been used for centuries, particularly in traditional European practices, as a "cleansing" and balancing herb. While they share some of the antioxidant properties of the fruit, the leaves possess their own unique profile of compounds that focus primarily on metabolic and circulatory health.

Core Bioactive Markers:

• Myrtillin (Glucoquinines): These are the key compounds in the leaf traditionally associated with the herb’s ability to support healthy glucose metabolism.
• Tannins: Provide an astringent quality that helps "tone" and strengthen the vascular system, supporting healthy vessel walls.
• Flavonoids: A broad spectrum of protective compounds that defend the body’s tissues and support healthy blood flow.
• Organic Acids: Assist in maintaining the body's internal acid-base balance, supporting efficient metabolic function.

Key Physiological Properties:

• Glycemic Modulator: Traditionally used to help the body process carbohydrates and maintain steady, balanced energy levels throughout the day.
• Vascular Astringent: Gently tones the blood vessels, supporting healthy circulation and reducing the feeling of "heaviness" in the limbs.
• Metabolic Restoration: Acts as a tonic for the entire metabolic system, helping to "re-tune" the body’s natural ability to regulate and process nutrients.
• Tissue Protector: Its antioxidant profile helps shield the delicate lining of the circulatory system from the stress of everyday life.
