Romania's Botanical Treasure Trove: From Meadow Weeds to Healing Herbs

Romania's diverse ecosystems create ideal habitats for an impressive variety of medicinal plants. Interestingly, some species currently classified as "unwanted meadow weeds" by agricultural authorities are actually plants with significant ethnomedicinal histories. Greater burdock (Arctium lappa), field eryngo (Eryngium campestre), and sorrel (Rumex acetosella) are among ten plants that Romanian landowners are required to remove from subsidized fields, despite their documented traditional uses not only in Romania but in multiple Eastern European countries 1 .

This apparent contradiction between agricultural policy and medicinal value highlights the complex relationship humans have with plants—what may be undesirable in one context may be therapeutic in another. Traditional applications of these plants are remarkably diverse: from the use of Cnicus benedictus (Blessed Thistle) for digestive issues and inflammation to Eryngium planum (Flat Sea Holly) for various ailments 6 . Meanwhile, Geum urbanum (Common Avens) has been valued for its tannin and phenolic acid content 6 .
