Came across a bottle of a 45%abv herbal liqueur from Ivano-Frankivsk in Western Ukraine called "Carpathian Balsam". It listed the ingredients which was useful -
Guilder rose berries (Virburnum opulus)
Black chokeberries (Aronia melanocarpa)
St. Johns wort
Sweet clover (Melilot) (Melilotus officialis)
Black currant leaves
Morello cherry leaves
So it is basically a Walnut liqueur (Nocino) with additional herbs, some of which have a medicinal quality. Sweet clover contains a blood thinner and St Johns wort is used as an anti-depressive. Black chokeberry is originally from U.S.A.
