Description
This amber Rexall-labeled bottle once contained Ol. Pini Pumilionis, or Oil of Dwarf Pine, a distilled essential oil obtained from the needles and young branches of the mountain pine (Pinus mugo). In early 20th-century pharmacy, this aromatic oil was valued for its antiseptic, expectorant, and stimulating properties.
The bottle’s Latin nomenclature and simple pharmaceutical design identify it as part of the Rexall Drug Store prescription stock, used for compounding medicinal preparations and aromatic inhalations. It likely held pure essential oil for apothecary use rather than a consumer preparation.
Condition
Very good condition with intact label and strong Rexall emblem. Light surface residue and dust within bottle; minor edge wear to cap and paper consistent with age. Label remains fully legible with ornamental border and caduceus emblem.

Historical context
The Rexall chain, formally the United Drug Company, was founded in 1902 and quickly became one of the most recognized American pharmacy brands. Under the “Rexall Drug Store” banner, local pharmacists were supplied with standardized proprietary medicines, compounding chemicals, and essential oils such as Ol. Pini Pumilionis.
Oil of Dwarf Pine was once a common pharmaceutical ingredient in inhalants, antiseptic washes, and liniments. Its vapors were thought to cleanse the respiratory tract and invigorate circulation. The Latin labeling style (“Ol.” for oleum) persisted through the 1940s as part of the medical profession’s long-standing tradition of using Latin for prescriptions.
Curious Facts, Ephemera, and Trivia
Pini pumilionis refers specifically to oil from the dwarf mountain pine (Pinus mugo), distinct from common pine oils derived from Pinus sylvestris.
The oil was sometimes blended with menthol and camphor to make inhalants for catarrhal conditions or rubs for chest congestion.
Rexall’s prescription labeling used standardized Latin titles to unify its 12,000-member pharmacy network across the United States.
Pine oils were once advertised as natural air purifiers long before the advent of modern disinfectants.
The pleasant scent and volatility of dwarf pine oil made it a favorite base for aromatic spirits of ammonia and vapor rub mixtures.
Excerpt

Why it is in the Cabinet
This Rexall bottle represents the quiet backbone of midcentury pharmacy — the essential oils and tinctures that formed the aromatic, chemical foundation of medicine before the antibiotic age. Its minimalist amber form and Latin label preserve the aesthetic of professional pharmacology in the pre-digital era. Together with related bottles such as Acetonum and Ol. Gaultheriae, it illustrates the enduring language of classical pharmacy carried into modern American practice.
