Lenitive electuary: what did Canale use it for?

Among the light purges with which the cure begins: for the choleric with syrup of roses, in a draught taken at dawn, and for the phlegmatic with honey of roses (ch. 2).

Lenitive electuary: what does modern science say?

Its senna made it a genuine laxative: senna leaf has a European Union monograph for the short-term treatment of occasional constipation. Culpeper says it “gently opens and mollifies the bowels.”

Pharmacognosy & Toxicology

Constituents
Mechanism
The senna is the laxative: its sennosides pass unabsorbed to the large intestine, where bacteria turn them into rhein anthrone, which quickens the colon and draws water and salts into it, so that the bowels move some eight to twelve hours later. Canale starts his choleric and phlegmatic patients with it.
Toxic dose
Culpeper allows a man of reasonable strength an ounce at bedtime; senna is not to be taken for more than a week, and in high doses for too long it has injured the liver.
Syndrome
The anthranoid purgatives
Standing
Senna leaf has a European Union monograph as a laxative for occasional constipation.

Constituent names open the compound’s record at PubChem, and “ChEMBL” beside a name opens its record at ChEMBL, the European Bioinformatics Institute’s database of bioactive molecules. Where a mechanism line was checked against ChEMBL (ChEMBL 37, read 1 October 2026), the check is shown with the measured value and its source paper, or says plainly that nothing has been measured. Doses are as the references give them, for description only; this is not medical advice. Each source carries the result of its check against Crossref, PubMed, or the authority’s page: see Verification.

In Their Own Words

Culpeper says lenitive electuary gently opens the bowels and brings away choler, phlegm and melancholy without trouble, and being cooling is good in pleurisies and for the wounded.

“It gently opens and molifies the bowels, brings forth choler, flegm, and melancholy, and that without trouble, it is cooling, and therefore is profitable in pleurisies, and for wounded people:”

Buchan says a teaspoonful of lenitive electuary two or three times a day generally proves an agreeable laxative, and that it also serves as a vehicle for stronger medicines such as jalap and scammony.

“A tea-spoonful of this electuary, taken two or three times a day, generally proves an agreeable laxative. It likewise serves as a convenient vehicle for exhibiting more active medicines, as jalaps, scammony, and such like.”
