I noticed fever few popped up in our food forest, unannounced the first season I suffered from migraines. I find it amazing that the food forest almost always knows what we need medicinally. Every time a new unknown volunteer arrives, I research to figure out what it is, and invariably notice its medicinal properties are totally aligned with something one of us really needs more of. As though all life is interconnected...
Though personally the only medicinal plants that really work wonders on my migraines have been linden flower (tilia) tincture and cannabis oil drops. A few drops of either under the tongue are great nervous system relief.
