The wild Teasel (Dipsacus sylvestris) grows commonly in waste places, having tall stems or stalks, at the bottom of which are leaves (like bracts) united at their sides so as to form a cup, open upwards, around the base of the stalk, and hence the term "Dipsacus," thirsty. This cup serves to retain rain water, which is thought to acquire curative properties, being used, for one purpose, to remove warts. The cup is called Venus' basin, and its contents, says Ray, are of service ad verrucas abigendas; also it is named Barber's Brush, and Church Broom.
The Fuller's Teasel, or Thistle (Dipsacus fullonum) is so termed from its use in combing and dressing cloth,—teasan, to tease,— three Teaselheads being the arms of the Cloth Weavers' Company. This is found in the neighbourhood of the cloth districts, but is not considered to be a British plant. It is probably a cultivated variety of the wild Teasel, but differs by having the bristles of its receptacles hooked.
The Sow Thistle (Sonchus oleraceus), named sonchus because of its soft spikes instead of prickles, grows commonly as a weed in gardens, and having milky stalks which are reputed good for wheezy and short-winded folk, whilst the milk may be used as a wash for the face. It is named also "turn sole" because always facing the sun, and Hare's Thistle (the hare's panacea, [560] says an old writer, is the Sow Thistle), or Hare's Lettuce because "when fainting with the heat she recruits her strength with the herb; or if a hare eat of this herb in the summer when he is mad he shall become whole." Another similar title of the herb is Hare's palace, since the creature was thought to get shelter and courage from it. Some suppose that the botanical term Sonchus signifies apo ton soon ekein, from its yielding a salubrious juice.
The Sow thistle has been named also Milkweed. According to tradition it sometimes conceals marvels, or treasures; and in Italian stories the words, "Open Sow Thistle" are used as of like significance with the magical invocation "Open sesame." Another name is "Du Tistel" or Sprout Thistle; because the plant may be used for its edible sprouts, which Evelyn says, were eaten by Galen as a lettuce. And Matthiolus told of the Tuscans in his day "Soncho nostri utuntur hyeme in acetariis."
The Melancholy Thistle (Carduus heterophyllus) has been held curative of melancholy. It grows most frequently in Scotland and the North of England, and is a non-prickly plant.
THYME.
The Wild English thyme (Thymus serpyllum) belongs to the Labiate plants, and takes its second title from a Greek verb signifying "to creep," which has reference to the procumbent habit of the plant. It bears the appellation "Brotherwort."
Typically the Thymus serpyllum flourishes abundantly on hills, heaths, and grassy places, having woody stems, small fringed leaves, and heads of purple flowers which diffuse a sweet perfume into the surrounding air, [561] especially in hot weather. Shakespeare's well known line alludes to this pleasant fact: "I know a bank where the wild Thyme grows."
The name Thyme is derived from the Greek thumos, as identical with the Latin fumus, smoke, having reference to the ancient use of Thyme in sacrifices, because of its fragrant odour; or, it may be, as signifying courage (thumos), which its cordial qualities inspire. With the Greeks Thyme was an emblem of bravery, and activity; also the ladies of chivalrous days embroidered on the scarves which they presented to their knights the device of a bee hovering about a spray of Thyme, as teaching the union of the amiable and the active.
Horace has said concerning Wild Thyme:—
