potion
🧪 filtro = Latin philtrum, Greek philtron, from philein 'to love' + -tron tool
Spanish filtro in the love-potion sense comes from Greek philtron, a charm for making someone love you, built on philein, to love. Don't confuse it with the everyday filtro meaning filter, which has a separate origin. The philtrum, the groove under the nose, shares the same Greek root.
