French brandy (the spirituous base of the Cordial Balm of Gilead)
botanical
MECHANISM CLAIMED
Brandy is not named in Solomon's advertising, which presents the balm as a preparation of 'the choisest balsams' compounded by long and laborious process. The advertised effect, that the cordial braces and invigorates the nervous system and gives new tone to the vital functions, was attributed to the secret balsamic medicine rather than to its alcohol content. The proprietor's affidavit was the device that kept the brandy base undisclosed.
MECHANISM ACTUAL
Ethanol from the brandy is the obvious active agent and accounts for the immediate 'serenity and cheerfulness' the cordial produced. Alcohol is a central-nervous-system depressant with no power to restore vigour, cure nervous consumption, or renew a failing constitution; sustained use of a high-proof tonic carries the harms of alcohol rather than any restorative benefit. The aromatic additions (cardamom and other spices) flavour the spirit, and the cantharides identified by McLaren is a toxic vesicant rather than a restorative. The balm's effect was therefore that of a flavoured, spiced brandy sold as a medicine.
INTERVENTIONS USING IT
NOTES
French brandy is the spirituous base that contemporary rumour and later historians identify as the real substance of the Cordial Balm of Gilead. Solomon never disclosed the formula, swearing on affidavit in 1796 that he was its sole inventor and had revealed the ingredients to no one, so the composition is reconstructed from secondary scholarship: William Helfand (quoted in Mugglestone 2021) describes a few herbs and spices dissolved in a substantial percentage of old French brandy, and Angus McLaren (2007) gives cardamom, brandy, and cantharides. The advertising attributed the cordial’s effect to a secret medicine of choice balsams, not to alcohol, but ethanol is the plain active agent and explains the immediate cheering effect. Alcohol does not restore vigour or prolong life; the balm was, in substance, a spiced brandy sold at half a guinea a bottle as a restorative for failing constitutions.
