They have antibacterial and fungistatic properties, as well as anti-inflammatory and hemostatic effects. In the 19th century, decoctions and infusions of blackberry leaves were recommended to treat catarrh of the throat, stomach, and intestines, hoarseness, cough, peptic ulcers, and chlorosis, as well as pain in the appendix, excessive menstrual bleeding, and white vaginal discharge.”Wodne wyciągi z liści jeżyny obniżają poziom glukozy we krwi, działają ściągająco na błony śluzowe, hamują nieżyt przewodu pokarmowego.

In rats, a cream containing blackberry leaf extract improved wound healing and supported tissue regeneration.
Aim of the study: Rubus ulmifolius (RUI) Schott, commonly known as wild blackberry, is a perennial plant recognized for its traditional medicinal uses and diverse biological activities. This study aimed to evaluate the wound-healing efficacy of a topical cream formulated with RUI leaf extract.
Results: Biochemical analysis revealed significant downregulation of pro-inflammatory markers (interleukin-1β and matrix metalloproteinase-9) and upregulation of anti-inflammatory and regenerative markers (IL-10, VEGF, PDGF, and RUNX2). Histopathological examination further supported these findings, showing enhanced granulation tissue formation and re-epithelialization. These results suggest that R. ulmifolius leaf extract cream holds significant promise as a therapeutic agent for promoting effective wound healing.

Blackberry leaf extract relaxed blood vessels and lowered blood pressure in rats, and also showed antioxidant activity.
Aim of the study: Wild blackberry (Rubus ulmifolius Schott) is a culinary and medicinal plant traditionally used to treat various ailments, including hypertension. This study evaluated the vasorelaxant effects of five crude leaf extracts of R.
Results: MERu also demonstrated potent antioxidant activity and was rich in polyphenols, particularly tannins. Sixteen compounds were identified, notably rubanthrone A, a galloyl-bis-HHDP glucose derivative, ellagic acid, and quercetin-3-O-β-D-glucuronide. These results suggest that R. ulmifolius may have therapeutic potential for hypertension and exhibits promising characteristics as a functional food.

A review describes how blackberry and other berry leaves contain compounds with antioxidant and anti-inflammatory properties.
Aim of the study: Berry fruits are recognized, worldwide, as "superfoods" due to the high content of bioactive natural products and the health benefits deriving from their consumption. Berry leaves are byproducts of berry cultivation; their traditional therapeutic use against several diseases, such as the common cold, inflammation, diabetes, and ocular dysfunction, has been almost forgotten nowadays.
Results: The main bioactive compounds in berry leaves are similar to those in berry fruits, i.e., phenolic acids and esters, flavonols, anthocyanins, and procyanidins. The leaves are one of the richest sources of chlorogenic acid. In various studies, these secondary metabolites have demonstrated antioxidant, anti-inflammatory, cardioprotective, and neuroprotective properties. This review focuses on the phytochemical composition of the leaves of the most common berry species, i.e., blackcurrant, blackberry, raspberry, bilberry, blueberry, cranberry, and lingonberry leaves, and presents their traditional medicinal uses and their biological activities in vitro and in vivo.
