Earth smoke (Fumaria officinalis)
Fumaria officinalis is a species of plant in the poppy family (Papaveraceae). Fumaria is an annual, herbaceous plant that grows to a height of 10 to 50 cm.
Fumitory is an incense that was already used by our Germanic and Celtic ancestors. It was also called elf smoke. Wizards and witches used it to contact the deceased or to make themselves invisible (which I have not yet succeeded in doing). In the Middle Ages it was smoked to drive out evil spirits.
