How to use it: Use a clearly identified dried-bilberry-fruit medicinal preparation; ordinary fresh blueberries or fresh bilberry extracts do not automatically inherit this claim. Seek care if symptoms persist beyond 3 days.
EMA traditional-use guidance applies to adults and adolescents over 12 years. Continue fluid and electrolyte replacement; do not rely on bilberry when dehydration or other red flags are present.
Get medical care for symptoms that are severe, last longer than expected, get worse, or otherwise concern you.
Practical ways to use the ingredient may not provide the same form or amount discussed in the evidence.
