THE SWALLOW’S HERB.
Old authors tell us that when the young swallows are hatched, they are blind for some time, and that the parent birds bring to the nest a plant called Chelidonium, or Swallow’s herb, which has the property of restoring sight. This popular fallacy appears to be widely disseminated. The plant is the well-known Celandine (Chelidonium majus). It belongs to the Papaveraceæ, or poppies, and may be found growing in waste places to the height of two feet or more. It is brittle, slightly hairy, and full of a yellow, fœtid juice, and bears small yellow flowers in long-stalked umbels.
The name Chelidonium is derived no doubt from the Greek χελιδων, a swallow: but the reason for its being thus named is not so obvious. Some authors assert that it was so called on account of its flowering about the time of the arrival of the swallow, while others maintain that it derived its appellation from being the plant medicinally made use of by that bird.
The belief that animals and birds possess a knowledge of certain plants which will cure a disease, or benefit them in some way, is very ancient, and this particular plant is alluded to by old authors as being especially selected for the purpose. Pliny observes (Hist. Nat. fol. 1530, p. 461, xv.): “Animalia quoque invenire herbas, inprimisque chelidoniam. Hac enim hirundines oculis pullorum in nido restituunt visum, ut quidam volunt, etiam erutis oculis.” (!) And the same author further remarks: “Chelidoniam visui
saluberrimam hirundines monstravere vexatis pullorum oculis ilia medentes.”
Gerard, referring to this plant, in his “Herball, or Generall Historie of Plantes” (1597), observes:—“It is called celandine, not because it then first springeth at the comming in of the swallowes, or dieth when they goe away; for as we haue saide, it may be founde all the yeere; but because some hold opinion that with this herbe the dams restore sight to their yoong ones when their eies be out, the which things are vaine and false: for Cornelius Celsus in his sixt booke doth witnesse that when the sight of the eies of diuers yoong birdes be put foorth by some outward meanes, it will after a time be restored of itselfe, and soonest of all the sight of the swallow, whereupon, (as the same saith) that the tale or fable grew, how, thorow an herbe the dams restore that thing, which healeth of itselfe: the very same doth Aristotle alleadge in the sixt booke of the historie of liuing creatures: the eies of young swallowes, saith he, that are not fledge, if a man do pricke them out, do grow againe, and afterwards do perfectly recouer their sight.” Subsequently, when speaking of the “virtues” of the plant, the sage Gerard continues:—“The iuice of the herbe is good to sharpen the sight, for it clenseth and consumeth awaie slimie things that cleaue about the ball of the eie, and hinder the sight.” The root was considered good for yellow-jaundice, and also (being chewed) for toothache. Gerard adds, “The roote cut in small peeces is good to be
giuen vnto hawkes against sundrie diseases;” and Turbervile, in his “Booke of Falconrie” (1611), treats of a cure for “a blow giuen to the eye, or of some other mischance,” as follows:—“Sometimes the eyes of hawkes are hurt by some mishappe, some stripe, or otherwise, as I said afore. Against such unlooked-for mischances, Master Malopin, in his boke of the Prince, willeth to take the juice of Celondine, otherwise Arondell, or Swallowes hearbe, and to convey it into the eye. And if it bee not to be had greene, to take it drie, and to beat it into powder, and to blow it into her eye with a quill, and this shall recure the hawke.”
A marginal note to this paragraph informs us that “Arondell” in French is “Hirundo,” a swallow, otherwise called “Chelidon.”
Parkinson, in his “Theatrum Botanicum” (1640), alludes to two species of Celandine, C. major and minor, and says:—“Some call them Chelidonia major and minor, and tooke the name, as Dioscorides saith, because it springeth when swallowes come in; and withered at their going away (which is true in neither, the greater, whereof Dioscorides chiefely speaketh, being greene both winter and sommer; and the lesser springeth before swallowes come in, and is gone and withered long before their departure). Dioscorides likewise, and Pliny also, say it tooke that name from swallowes that cured their young ones’ eyes, that were hurt,
