Safety & Precautions

High Tannin Content: Due to high tannin concentrations, excessive long-term consumption of strong blackberry leaf preparations may cause mild stomach upset or nausea in sensitive individuals.

Constipation: Individuals prone to chronic constipation should use astringent tannin-rich herbs cautiously, as they can firm stools further.

Iron Absorption: High tannin intake taken simultaneously with iron supplements or iron-rich meals may temporarily reduce iron absorption.

Pregnancy & Breastfeeding: Culinary tea amounts are generally considered safe, but concentrated therapeutic extracts should be approached with professional guidance during pregnancy.
