Rubi fruticosi folium contain 5-14% tannins (gallotannins), flavonoids and various organic acids (malic acid, oxalic acid, succinic acid) and essential oils.

The ingredients of blackberry leaves have an astringent effect. They also have an antioxidant effect.

Blackberry leaves are used for acute, non-specific diarrhoea and mild inflammation of the mouth and throat mucosa.

The usual daily dose of the drug is 4.5 g and is administered (either alone or combined with other drugs) as a tea infusion or mouthwash or in another preparation for ingestion.

Fermented blackberry leaves (less tanning agents) are a popular decaffeinated substitute for black tea and are a common ingredient of house teas. It is possible to collect blackberry leaves yourself and then dry them. Care should be taken to dry the blackberry leaves slowly and with good ventilation, as they will not ferment if dried quickly in the sun.
