Because precision makes all the difference in aromatherapy, we offer a selectionof HECT and HEBBD chemotyped essential oils on Soin-et-Nature. These are rigorously tested extracts, chosen for their quality, traceability, and therapeutic effectiveness. Each oil is unique, derived from an identified plant, harvested under optimal conditions, and distilled to preserve its integrity. Whether you’re looking to relieve pain, boost your immune system, or simply restore balance, these essential oils offer a natural, safe solution tailored to your needs.
More details
The chemotype of an essential oil is defined by the concentration of the most abundant molecule in the oil.
For example,thymol-type thyme essential oil contains 50% thymol, which defines its chemotype. A molecule is generally only considered to be present in an essential oil if it exceeds 10%. All essential oils for which the percentage of a molecule is not specified contain only trace amounts of that molecule.
The chemotype used in aromatherapy allows us to identify chemical variations in secondary metabolites within the same species that are due to environmental factors (altitude, sunlight, temperature, humidity, etc.). Thus, the essential oil produced by two plants of the same species, despite their very similar genotypes and morphology, may exhibit significant variations in chemical composition. This is therefore a very important concept in aromatherapy.
An essential oil can be extracted from any part of a plant as long as that part possesses the structures necessary to produce it. Consequently, many essential oils are derived from flowers, leaves, seeds, fruits, rhizomes, etc. A single plant from the same biotope (a habitat characterized by certain conditions such as temperature, humidity, etc.) can synthesize essential oils with very different compositions and scents depending on the specific part of the plant from which they are derived. The best-known example is the bitter orange tree, from which three distinct essential oils can be extracted. The leaves yieldpetitgrain bigarade essential oil, the flowers yieldneroli essential oil, while the fruit peel yields bitter orange peel essential oil.
The plant that provides the botanical raw material may be cultivated or harvested in the wild. The conditions of cultivation, harvesting, drying, storage, etc., determine the quality of the plant and, consequently, that of the essential oil produced. If the plant is cultivated, the cultivation must, at a minimum, be organic and therefore free of chemicals (pesticides, herbicides, etc.) that could pollute the soil. The plant must also grow in its natural habitat or a very similar one.
There are various methods for extracting the essential oil produced by aromatic plants. Of these methods, the European Pharmacopoeia recognizes only three for producing a product that can be called an essential oil:steam distillation, dry distillation for stems and bark in a suitable apparatus, or a suitable mechanical process without heating for citrus fruits.
Other techniques: There are other methods for extracting essences; however, the resulting product cannot be defined as an essential oil.
Unlike vegetable oils, essential oils are volatile, which allows them to be extracted using steam. With a few rare exceptions (cinnamon bark, clove), their density is lower than that of water. They are immiscible in aqueous solutions but soluble in common organic solvents. Essential oils also interact with polarized light, and this property is used to verify their quality. The specific rotation of an essential oil further helps identify a pure, natural oil. Finally, their refractive index “n” is high. Ranging in intensity from pale to vivid, the entire color spectrum is represented: from the blood-red of certain savory varieties to the blue of Chamomilla recutita, and the pale green of Citrus bergamia. Under a UV lamp, one can even observe the ultraviolet light emitted by mandarin.
Essential oils are complex substances; they may contain:
However, the composition can vary significantly depending on the plant from which the essential oil is derived, its geographic origin, climate, altitude, extraction method, the skill of the distiller, etc.
