On chemical ecology

Obtaining the oil that is so important in terms of chemical ecology for plants, a kind of "memory" of that plant life.

The volatile compounds compressed in a essential oil mediate the relationship of a plant with abiotic factors such as light, temperature, draught, CO2 levels and ozone levels, and biotic factors such as competitors (both interspecific and intraspecific), microbial pathogens, herbivores and other harmful insects, and beneficial animals such as pollinators and seed dispersers.

Among natural plant products, essential oils deserve particular attention not only because of their uses but also because of the co-evolutionary beauty and information they give us (of the life and stresses of that plant).
