Derivation of the botanical name:
Convolvulus, Latin, convolvere, "to twine around"; "a bindweed" (Plinius), from convolvo, volvi, volutum, ere "to droll together, roll up, intertwine."
scammonia, resin from the root of Convolvulus scammonia, a mild cathartic gum-resin.
- The standard author abbreviation L. is used to indicate Carl Linnaeus (1707 – 1778), a Swedish botanist, physician, and zoologist, the father of modern taxonomy.
Theophrastus, who wrote his Enquiry into Plants around 300 BCE, mentions Convolvulus scammonia, Scammony, as a plant with medical properties but does not elaborate. Enquiry into Plants: Book 4.5.1. seeks cold regions; Book IX of the juices of plants, and the medicinal properties of herbs: 9.1.3. root produces a gum; 9.1.4. gum has medical properties; 9.9.1 root and juice used 9.20.5.juice only used.
Pliny the Elder (23-79CE), Natural History discusses the use of Scammony at lenght. Book XIV 110, XXV 54, XXVI 59, 90, 93, 114, 157, XXVII 79
