Potássio em Steiner (2007)

We must now look for a plant which by its own relationship between potassium and silicic acid can impart to the dung — once more, if added to it in a kind of homoeopathic dose — the corresponding power. And we can find it. This, too, is a plant which if it only grows among our farms, has a most beneficial influence in this direction. It is none other than the common dandelion (taraxacum officinale).
