The Salvation of Salvia apiana (White sage)

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 Immunomodulating Potential of Essential Oils in Relieving Asthma

Asthma

Among the respiratory conditions for which essential oils show promise is bronchial asthma.

Asthma affects some 339 million people worldwide and is the most common chronic disease among children (Morales, 2018). Asthma is characterized by chronic inflammation of the airways of the lungs with symptoms that include wheezing, shortness of breath, tightness of the chest, excessive mucus production, and cough. Asthma may also be classified as atopic (extrinsic) or non-atopic (intrinsic), based on whether symptoms are precipitated by allergens (atopic) or not (non-atopic) (Kumar at al, 2010). Allergic mechanisms are involved in about half of people with asthma.

Atopic asthma commonly involves an infiltration of the airways by components of the immune system such as eosinophils, mast cells, and lymphocytes together with a thickening of the bronchial walls and hypertrophy/ hyperplasia of the smooth muscle of the airways (Cheng et al, 2018). (Hypertrophy refers to an increase in the...
