Wild Blueberry

Vaccinium angustifolium
Read before use: the information below describes traditional and informational uses — it does not replace the advice of a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment, or use in children, seek advice before use.
The leaves, richer in tannins and active compounds than the berries, should not be consumed over extended periods without the advice of a healthcare professional. Regular and prolonged use of the leaves should be avoided during pregnancy or breastfeeding, as well as in young children, without prior medical advice. In case of diabetes treatment or anticoagulant medication use, consult a professional before any regular use of the leaves. Fresh or dried berries, consumed as common food, do not present any particular risk in healthy adults.
Infusion — Dried Berries

Berry infusion

Steep one tablespoon of dried and lightly crushed berries in a cup of hot water for ten minutes. Strain and drink warm, optionally sweetened with a little honey. 1 to 2 cups per day, for a course of a few days.

Decoction — Leaves

Leaf decoction

Gently boil a small amount of dried leaves in water for a few minutes, then let steep off the heat. This preparation, more concentrated than berry infusion, should be used with moderation and on professional advice for regular use. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.

Compress — Leaves

Soothing compress

Soak a clean cloth in cooled leaf decoction and apply to the affected area for a few minutes. Repeat if needed, avoiding broken or very sensitive skin. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.
