Hyssop

Minty-camphoraceous with a green, slightly sweet edge. Hyssop smells like an herbal liqueur poured over crushed leaves — medicinal and aromatic, with an unexpected fruity undertone.

The Full Story
Did You Know?
Hyssop is one of the herbs mentioned in the Bible associated with ritual purification — 'Purge me with hyssop, and I shall be clean' (Psalm 51:7). However, biblical scholars debate whether the plant referred to in the original Hebrew (ezov) is actually Hyssopus officinalis or another local aromatic herb, possibly a species of oregano or caper.
Extraction & Chemistry
Extraction method
Essential oil is produced by steam distillation of the flowering aerial parts of Hyssopus officinalis. Mean oil yield is approximately 0.9-1.1% on dry weight basis. Supercritical fluid extraction (SFE) has been investigated as an alternative, yielding different proportional compositions — particularly varying pinocamphone levels (0.7-13.6%) depending on extraction parameters (optimal: 45C, 100 atm, 25 min static, 20 min dynamic with methanol co-solvent). Major cultivation regions include France, Hungary, Italy, and the Balkans.

In Perfumery
Hyssop oil functions as a top-to-heart herbal modifier, used in aromatic, fougere, and herbal-medicinal accords. Its camphoraceous-minty freshness provides lift and green complexity, while the underlying fruity-sweet quality softens what could otherwise be harsh. It works naturally alongside lavender, sage, rosemary, and myrtle. The pinocamphone content (neurotoxic at high concentrations) limits dosage in formulation. Hyssop also appears in historical and liturgical fragrance recreations — its mention in the Bible (Psalm 51:7) connects it to purification rituals. The decumbent variety (Hyssopus officinalis var. decumbens), which is naturally low in pinocamphone, offers a safer alternative. Hyssop is not featured in any current PREMIEREPEAU fragrance.
