The Spiritual Directors of Aromatherapy Lactones

Based on their distinguishing qualities, each of the 12 chemical families can be divided into 12 Archetypes and their characteristic Elemental Powers.

These 12 archetypes, and their chemical families, tell us about the therapeutic properties, actions and effects of essential oils.

You can select essential oils to use alone, or in a formulation, to promote healing for specific conditions, based on their specific archetype and therapeutic chemical properties, actions and effects.

PLEASE NOTE: Depending upon the percentage(s) of a chemical component that comprises an oil, it can be classed in more than one chemical family.

LACTONE PROPERTIES

Lactones may well be the most obscure chemical component in aromatherapy. Although Lactones are present in many plants, they are only found in small amounts in essential oils. Typically Lactones are only found in cold pressed or expressed oils, and some absolutes, like jasmine. This is because their molecular weights are far too high for them to come through in the distillation of a plant. 

Lactones are ‘cyclic’ esters in which the functional group of the ester has become part of a ringed structure with carbon atoms. They can be mono- or sesquiterpenoids. The cyclic nature of lactones lends a deepening and lasting quality to the protective and nurturing effect of plant esters.

The names of lactones are quite variable, though suffixes like, -olide, -in, -ine, -one and -lactone are fairly common.

Lactones contribute to the aroma of fruits, butter, cheese, and other foods. The scent that lactone contributes to a plant varies. Their fragrance and flavor characteristics have been described from coconut, peach, prune and vanilla-like to creamy, musky and oily.

Even though the percentage of lactones present in essential oils may be very low, lactones are thought to play an especially important role as healing and clarifying agents in aromatherapy, Their notable mucolytic, expectorant and fever-reducing actions, makes them especially effective for treating respiratory congestion and bronchitis.

Coumarins & Furocoumarins

A review on natural coumarin (a type of lactone) compounds for their pharmacological activity showed anti-inflammatory, antiallergic, antiviral, antimutagenic, and anticarcinogenic properties.

Coumarins act as anticoagulants (blood thinners) and hypotensors (lower blood pressure). Coumarins stimulate and uplift the senses, as well as have a calming and sedating effect.

Furocoumarins are found in Bergamot, Mandarin, Orange and Lemon.
