Blackberry leaf is an astringent leaf tea traditionally used to support digestion, especially when stools are loose. Its tannins can help ‘tighten’ and soothe tissues. It’s also used as a gargle for mouth and throat comfort.

Key Benefits

Common Issues It May Help With

How To Use (Simple)

Taste / Notes

Mildly bitter, earthy, drying/astringent.

Evidence Level

Traditional use is strong for astringent support; clinical evidence is limited but the mechanism (tannins) is well understood.

Cautions

Tannins can irritate sensitive stomachs and may reduce absorption of some nutrients/meds if taken at the same time. Avoid long-term heavy use. If diarrhea is severe, bloody, or lasts more than 2–3 days, seek medical care.

Interactions

May reduce absorption of oral medications due to tannins—separate by 2 hours If taking iron supplements, separate timing (tannins can reduce absorption) No major drug interactions at typical tea use levels
