The Salvation of Salvia apiana (White sage)

All things are bound together. All things connect.” -Chief Seattle

Mass Extinction

Scientists revealed in 2010 that the Earth is undergoing its sixth mass extinction whereby over 1,000,000 species are facing extinction (1). One of the two factors primarily contributing to this alarming number is habitat destruction, fuelled in particular by monoculture, urban sprawl, and unsustainable management of land. Species directly affected by habitat destruction include essential oil-bearing plants. Approximately 9% of 400 essential oil-bearing plants traded on the world market are recognized as threatened or near-threatened (2), and this number continues to increase. In the last year alone, the conservation status for three aromatic plants were elevated, and include Salvia apiana - white sage - which was added to the United Plant Savers ‘At-risk’ list.

The Sedative and Anxiolytic Activities of Cedrol and Virginian Cedarwood Essential Oil

Cedrol

Cedrol is a tricyclic sesquiterpene alcohol commonly occurring in the essential oils of conifer trees, especially those belonging to the Cupressus and Juniperus genera. It occurs in essential oil of Juniperus virginiana (Virginian, red or Eastern red cedarwood) (Figure 1) at proportions of approximately 24-32% (ter Heide et al, 1988; Kitchens et al, 1971). The compound presents minimal risk in terms of skin irritancy, allergenicity and toxicity (Tisserand & Young, 2014).

Cedrol has exhibited in vitro antimicrobial activity against Gram-positive bacteria and yeast, and cytotoxic activity against human lung, liver and oral cancer cells (Su et al, 2012). The compound was also shown to contribute to the potentially beneficial effects of the methanol extract of Juniperus chinenesis on Alzheimer’s disease, specifically through inhibiting the enzymes...
