The term Dock is botanically a noun of multitude, meaning originally a bundle of hemp, and corresponding to a similar word signifying a flock. It became in early times applied to a wide-spread tribe of broad-leaved wayside weeds. They all belong to the botanical order of Polygonaceoe, or "many kneed" plants, because, like the wife of Yankee Doodle, famous in song, they are "double-jointed;" though he, poor man! expecting to find Mistress Doodle doubly active in her household [158] duties, was, as the rhyme says, "disappointed." The name "Dock" was first applied to the Arctium Lappa, or Bur-dock, so called because of its seed-vessels becoming frequently entangled by their small hooked spines in the wool of sheep passing along by the hedge-rows. Then the title got to include other broad-leaved herbs, all of the Sorrel kind, and used in pottage, or in medicine.
Of the Docks which are here recognized, some are cultivated, such as Garden Rhubarb, and the Monk's Rhubarb, or herb Patience, an excellent pot herb; whilst others grow wild in meadows, and by river sides, such as the round-leafed Dock (Rumex obtusifolius), the sharp-pointed Dock (Rumex acutus), the sour Dock (Rumex acetosus), the great water Dock (Rumex hydrolapathum), and the bloody-veined Dock (Rumex sanguineus).
All these resemble our garden rhubarb more or less in their general characteristics, and in possessing much tannin. Most of them chemically furnish "rumicin," or crysophanic acid, which is highly useful in several chronic diseases of the skin among scrofulous patients. The generic name of several Docks is rumex, from the Hebrew rumach, a "spear"; others arc called lapathum, from the Greek verb lapazein, to cleanse, because they act medicinally as purgatives.
The common wayside Dock (Rumex obtusifolius) is the most ordinary of all the Docks, being large and spreading, and so coarse that cattle refuse to eat it. The leaves are often applied as a rustic remedy to burns and scalds, and are used for dressing blisters. Likewise a popular cure for nettle stings is to rub them with a Dock leaf, saying at the same time:—
"Out nettle: in Dock;
Dock shall have a new smock."
[159] or:
"Nettle out: Dock in;
Dock remove the nettle sting."
A tea made from the root was formerly given for the cure of boils, and the plant is frequently called Butterdock, because its leaves are put into use for wrapping up butter. This Dock will not thrive in poor worthless soil; but its broad foliage serves to lodge the destructive turnip fly. The root when dried maybe added to tooth powder.
It was under the broad leaf of a roadside Dock that Hop o' My Thumb, famous in nursery lore, sought refuge from a storm, and was unfortunately swallowed whilst still beneath the leaf by a passing hungry cow.
The herb Patience, or Monk's Rhubarb (Rumex alpinus), a Griselda among herbs, may be given with admirable effect in pottage, as a domestic aperient, "loosening the belly, helping the jaundice, and dispersing the tympany." This grows wild in some parts, by roadsides, and near cottages, but is not common except as a cultivated herb ill the kitchen-garden, known as "Patience-dock." It is a remarkable fact that the toughest flesh-meat, if boiled with the herb, or with other kindred docks, will become quite tender. The name Patience, or Passions, was probably from the Italian Lapazio, a corruption of Lapathum, which was mistaken for la passio, the passion of Christ.
