Those who receive my newsletter, may have read my ramblings on foraging on hospital grounds, and how there is much more nourishment to be found there, than there is in hospital meals. But how about our fields? We love to get our local vegetables and berries at our CSA-farm. But we don't just see it as a place to get fresh organic produce. It's one of the best places to get our edible weeds as well. And one of the frequently found wild plants there is field pansy (Viola arvensis).
Field pansy was shown to contain substances that have shown to possess toxic activity against human cancer cells and is therefore looked at as a potential drug lead. Apart from that, they contain vitamin C, vitamin A, salicyl acid (that's aspirin in plant form, and usually a lot better as it doesn't have all the side effects it has in pill form), and many more.
And it's not hard to find on fields - the seeds spread so fast that the plant is also called Johnny-Jump-Up.
So guess what - it's pulled out (pulling out being the best case scenario) as a weed, and thrown on the compost heap. In worse scenarios the soil and the environment are poisoned because people want to get rid of this plant.
How does the combination of the two previous paragraphs above sound to you? Maybe eating wild plants is just that: connecting the dots.
