Bioactivity of Cineole
Cineole and other components of eucalyptus oil are readily biodegradable, unreactive and relatively non-toxic (Webb and Pitt, 1993; Haley, 1982; Patel and Wiggins, 1980; Opdyke, 1975; Stoner et al., 1973; Roe and Field, 1965; MacPherson, 1925). Eucalyptus oil carries the US Food and Drug Authority classification GRAS (Generally Regarded as Safe) and is approved for incorporation into foods such as chewing gum and throat lozenges at low concentrations
