Additional information

Habitat and botanical description

It is a tufted perennial that grows on a thick, brownish-red underground rhizome that can reach 90 cm in height. The erect, branched stem is up to 50 cm high. It is hollow, cylindrical, brittle and hairy. The lower leaves, arranged in a rosette, are stalked, while the upper stem leaves are sessile, alternate, pinnate (5-7 segments), oval, lobed and crenate (sometimes toothed). When the leaves and stems are broken, an abundant corrosive yellow-orange latex flows out, the colour being due to a pigment (chelidoxanthin) which oxidises in the air. The flowers are yellow and dialypetal, with 4 crossed petals, 2 deciduous yellowish sepals and numerous stamens. The fruits are narrow, hairless, bumpy siliques.
It grows on rocky outcrops, rubble heaps, roadsides and old walls, in cool places up to 1,500m. It can sometimes be found fresh in winter.

Harvest time

The dried buds are harvested at the beginning of flowering. Fresh latex is harvested before flowering.

Mythology / History / Anecdotes and traditional virtues

In Latin 'chelidonium' means 'swallow', so the plant owes its name to the fact that its flowering coincides with the arrival of the swallows. According to Pliny, the plant owes its name to the fact that swallows rub fragments of the plant into the eyes of their young to help them open. Celidonia has often been considered a magical plant, sometimes associated with black magic. For medieval alchemists, its yellow sap could be the means of transforming base metals into gold, hence its nickname 'Gift from Heaven'. The name "éclaire" refers to the bright yellow flowers that "light up the coming of spring", evoking small plant suns that seem to be a source of light, hence the use of the plant as an antiophthalmic (it was even said to restore sight to the blind) according to the theory of signatures. According to the same theory, it was also used to treat jaundice and gallstones.
