I never thought I'd see the day I'd be diving into the airy-fairy, woo-filled world of flower essences, but if you were to rummage amongst all the jars of infused oils and deeply coloured tinctures on the top of my china cabinet today you'd find 4 jars and several small brown dropper bottles of what looks very much like plain water.
Flower essences are sorta-kinda like homeopathic remedies. It's one of those "they're the same only different" deals. Their similarity is that both are extremely diluted - I'll tell you just how diluted in a bit - but they also differ in a very important way.
