Eucalyptol

Eucalyptol and 1,8-cineole are the same name here

Eucalyptol is the common name for 1,8-cineole, an oxygenated monoterpene found in several plants. Keeping both names visible helps when a laboratory report says cineole and a paper says eucalyptol. Neither name identifies a medicine or a predictable respiratory effect.

There is one defined human trial in this set

A double-blind, placebo-controlled trial studied an isolated eucalyptol preparation in adults with severe asthma. It measured inflammatory markers and asthma-related outcomes under that protocol. This is human clinical evidence for the preparation and population studied. It did not test a cannabis product, and it does not establish general use of eucalyptol for asthma.

A secondary plant-chemistry reference supports the cineole terminology. It is provenance for the name, not an additional clinical result.

Eucalyptol trials and label results are different evidence

An eucalyptol or 1,8-cineole line identifies a constituent in a particular sample. It does not make that sample equivalent to the defined preparation in the asthma trial, and it cannot predict a person’s respiratory response. The evidence supports a narrow human study, not a terpene-based product recommendation.
