Galega officinalis, commonly known as galega, goat's-rue, French lilac, Italian fitch, or professor-weed, is an herbaceous plant in the Faboideae subfamily. It is native to the Middle East, but it has been naturalized in Europe, western Asia, and western Pakistan. The plant has been extensively cultivated as a forage crop, an ornamental, a bee plant and as green manure. However, the plant has proved too toxic for widespread agricultural use, with the potential to induce tracheal frothing, pulmonary oedema, hydrothorax, hypotension, paralysis and death.
