Pharmacognosy & Toxicology

Constituents
Mechanism
Put undiluted on lint it is an antiseptic and styptic dressing for small cuts; in hot water it is breathed for bronchitis and laryngitis, and benzoin taken by mouth is mildly expectorant as it is excreted. It is a contact allergen: in a Melbourne clinic in 1999, 45 of 477 patients patch-tested positive to it, the third most common allergen there.
Toxic dose
External and inhaled; once also given by mouth, 2 to 4 mils, in chronic bronchitis.
Standing
Compound tincture of benzoin was in the BP and the USP of 1911, and the BPC gave a benzoin steam inhalation.

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.

Friar’s balsam: what lore surrounds it?

The London Pharmacopoeia of 1788 renamed its balsamum traumaticum “compound tincture of benzoin.”

In Their Own Words

Buchan thinks the balsam of some value but undeserving of the extravagant praise given it under names including Friar's Balsam, Jesuit's Drops and Turlington's Drops.

“This, though a medicine of some value, does not deserve the extravagant encomiums which have been bestowed on it. It has been celebrated under the different names of The Commander’s Balsam, Persian Balsam, Balsam of Berne, Wade’s Balsam, Friar’s Balsam, Jesuit’s Drops, Turlington’s Drops, &c.”

William Buchan, M.D., Domestic Medicine: or, a Treatise on the Prevention and Cure of Diseases by Regimen and Simple Medicines. With an Appendix, containing a Dispensatory for the Use of Private Practitioners, Dispensatory, Balsams: 'The vulnerary Balsam'. London: printed for A. Strahan, T. Cadell, 1791 (Project Gutenberg eBook #74359). The text, read in part

Buchan says this tincture is applied externally to heal recent wounds and bruises, and is also given internally for coughs, asthmas and complaints of the breast.

“This balsam, or rather tincture, is applied externally to heal recent wounds and bruises. It is likewise employed internally to remove coughs, asthmas, and other complaints of the breast.”
