ESSENTIAL OILS – All our essential oils are pure and 100% natural, undiluted with alcohol or any other substance. Essential oils are obtained through an expression, extraction, and/or a distillation of the plant’s volatile oils. Please use oils with caution, they are extremely concentrated.

extraction methods

Steam Distillation – regular steam or super heated steam is passed through the chopped or whole plant material, carrying over volatile substances. The steam is condensed by cooling and the Essential Oil is separated in a gravity funnel and filtered. Used for most Essential Oils like Lavender, Lavandin, Geranium, Cedarwood, Sandalwood, Citronella, Eucalyptus, Lemongrass, etc.

Cold Expression, Cold Pressed, By expression of the ripe peel of the fruit – used for Citrus Oils. The fruit peel is mechanically pressed to squeeze the Essential Oil out of the peel and is collected, centrifuged to remove water and juice and filtered. Used for most citrus oils such as Orange, Lemon, Grapefruit, Mandarin, Tangerine, etc.

Fractional Distillation – Distillation by heat in a distillation column in which rectification is used to obtain as pure a product as possible. A part of the vapor is captured and condensed based on boiling point usually in a distillation column with plates or packing material to help separate the components with similar boiling points. Also called Redistilled or Rectified

Solvent Extraction, Non-Aqueous Solvent Extraction – Volatile oils extracted from the plant material by volatile solvents such as Ethyl alcohol, Diethyl ether, Isobutane, Hexane, Cyclohexane, Methyl acetate, Butan-1-ol, etc., then the solvent is gently distilled off by heat and/or vacuum leaving the Oil behind. Used primarily for flower oils where heat from Steam distillation destroys the oil. Used for Cassie, Jasmine, Mimosa, Orange Flower, Rose, Violet Leaf etc.

Water Distillation, Hydrodistillation – the plant material is in direct contact with boiling water. The vapor is condensed by cooling and the Essential Oil is separated by gravity funnel. Examples are Cananga Oil, Clove Bud, Clove Leaf and Wintergreen Oil.

Solvents – Volatile solvents used to extract Flower Oils such as those listed under Solvent Extraction.

CARRIER OILS – These replenishing, plant-derived oils can be externally applied to the body to moisturize skin and improve overall tone and texture. They are NOT designed for consumption.
