Blueberry Leaf

Vaccinium corymbosum

Antioxidant

Blueberry leaf is used traditionally as a mild astringent tea and is sometimes included in blood sugar support blends. It’s not the same as eating blueberries (which are food-level nutrition).

Key Benefits

Traditional astringent tea for digestive comfort routines.
Sometimes used in metabolic and blood sugar support blends (traditional use).
Provides plant polyphenols (leaf compounds).

Common Issues It May Help With

Occasional digestive upset routines (traditional use).
Blood sugar support routines (traditional use; adjunct).
General wellness tea routines.

How To Use (Simple)

Tea: steep leaf 10 minutes; often blended with cinnamon or green tea.
Use consistently for a routine, not as a one-time ‘fix.’
Food: for nutrition, use blueberries themselves.

Taste / Notes

Mild, slightly tannic/herbal.

Evidence Level

Traditional use; limited clinical evidence for blood sugar claims, and effects vary.

Cautions

If you use this with diabetes medications, monitor blood sugar (may add to lowering effects in some people). Avoid overuse if prone to constipation.

Interactions

Use caution with diabetes medications (potential additive effect).
