In the summer of 2019 I collected wild carrot seed from waste ground and street verges within a one kilometre radius around my house in West Flanders and from the gardens of wild flowers planted in the city of Aalst by its head gardener Bart Backaert. The ripe seed heads are easy to identify as they turn inwards to take on the shape of a little bird nest. My intention was to see how much seed I would need to collect if I was to have a supply of the natural contraceptive, for one woman, for one year. I collected the seed heads on the stalk and bound them into bunches with the idea that this would make them easier to store and, later, to thresh the seeds loose. In their fresh state the bunches reminded me of bouquets.
There are numerous historical references to wild carrot seed as an anti-fertility agent. In works in the Hippocratic Corpus, Pliny the Elder, Dioscorides, Scibonius Largus, and Constantine the African, wild carrot seed is described as an abortifacient, emmenagogue or contraceptive. For a review of references and studies both historical and contemporary see Carrot seed for contraception: a review. Jansen G & Wohlmuth H. Australian Journal of Herbal Medicine 2014 26(1).
