Benzoin: what did Canale use it for?

In the oil for the bewitched (ch. 9).

Benzoin: what does modern science say?

Antiseptic; still in compound tincture of benzoin. Compound tincture of benzoin, the Friar’s balsam of the old chests, is still painted on skin to make dressings adhere and breathed in steam for colds; benzoic acid and its salts preserve foods and soft drinks the world over.

Pharmacognosy & Toxicology

Constituents
Mechanism
Benzoic acid is antiseptic and antifungal, and the resin painted on skin dries to a protective film, the “friar’s balsam” use; breathed in steam it is an expectorant by irritation. It is a recognised contact allergen.
Toxic dose
Safe externally; allergic dermatitis is common enough that it is in patch-test series.
Standing
Compound benzoin tincture is in the USP and the BP as a skin protectant and inhalation; the FDA declined to list it as a skin protectant in its 2003 monograph.

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.

Benzoin: what lore surrounds it?

Sumatra benzoin, rich in cinnamic acid, went to the apothecaries; Siam benzoin, sweeter, to the perfumers; benzoic acid, first obtained from the resin by sublimation in the sixteenth century, took its name from it.

Benzoin: what did the older authorities say?

Its name
From the Arabic lubān jāwī, “frankincense of Java,” worn down to benjoin by the Italian and French traders who brought it from Sumatra in the fifteenth century.
The churches
Burned it as incense, and in Russia and the Orthodox East it remains the chief ingredient of church incense; in the West it went into pomanders, pastilles, and the perfumes of the glovers.
