Sweet and warm with dominant coumarin: vanilla, dried hay, almond skin. Underneath the sweetness sits a green, slightly musty herbaceous note that synthetic coumarin cannot replicate. Richer and earthier than tonka bean, less sharp than fresh hay.
Deer tongue grass (Carphephorus odoratissimus, syn. Liatris odoratissima) is a perennial herb native to the southeastern United States, particularly the coastal plains from Virginia to Florida. The fresh leaves have almost no scent. As they dry, coumarin crystallizes on the surface, releasing a powerful sweet-herbaceous aroma similar to of vanilla, hay, and tonka bean.
The coumarin content reaches approximately 1.6% of dry weight, making deer tongue one of the richest natural sources of this molecule. Historically, the dried leaves were used to flavor pipe tobacco, a practice that continued in the American South well into the twentieth century.
In perfumery, deer tongue absolute is used as a natural source of coumar in with additional herbaceous complexity. It is a fixative and base note modifier, contributing warmth and sweetness to fougere, tobacco, and amber compositions. The scent is distinctly different from synthetic coumar in alone: it carries a green, slightly musty undertone that pure coumar in lacks. This earthy quality makes it useful in compositions seeking a naturalistic, tobacco-barn warmth rather than clean sweetness.

The FDA banned coumarin as a direct food additive in 1954 after rat studies linked high doses to liver damage. Deer tongue leaves, once a common tobacco flavoring in the American South, fell out of commercial use as a result.
Extraction & Chemistry
Extraction method: Solvent extraction of dried leaves yields an absolute. The drying process is essential: fresh leaves contain coumarin precursors that convert to free coumarin only during wilting and curing. Steam distillation is also possible but produces a different, lighter profile.
Deer tongue absolute is a base note fixative and modifier known for natural coumar in content. It anchors fougere, tobacco, amber, and hay accords with a sweet warmth that has more complexity than isolated coumar in. The green-musty undertone adds naturalistic depth to compositions. It functions in the same territory as tonk a bean absolute but with a distinctly more herbaceous, tobacco-adjacent character.
