When purchasing essential oils and different aromatherapy supplies it is crucial to consider the value. Not all organic oils are the same, oil value is dependent on the growing environment of the flowers and the removal techniques utilized.
There are two main classifications for essentials oils, food grade and therapeutic grade. Food grade or a lower quality oil and not good for inhalation. Therapeutic grade oils are of a better quality and higher purity and are preferred for most aromatherapy uses. It is important to learn about the different types and classifications of organic oils to know which type you might need.
The location that a plant is grown in can have a big influence on its price. Certain plants can only be grown in specific geographic locations, the subsequent scarcity of these plants will often drive up the price. Temporary factors such as annual harvests or shifting demand can also have an impact on quality alter price.
Apart from the environment in which a plant is cultivated the oil extraction method is the other major factor in its quality. Extraction is how the valuable oils and compounds contained in plants are removed and separated from unwanted chemicals or impurities. The two types of extraction are physical extraction and chemical extraction. Physical methods include steam extraction and a process called enfleurage. Supercritical extraction is a type of chemical extraction technique and can be used for obtained extremely pure and unadulterated compounds.
Essential oils and other organic compounds are classified as either food grade or therapeutic grade. Their chemical grade an Food Chemical Codex can provide insight into the make up and quality of oils. The FCC is a detailed listing of the chemical components of organic oils.
Though all chemicals should be extracted naturally from source flowers certain manufacturers use synthetic additives. Food grade organic oils should be avoided because of this, although the name makes them sound appropriate for aromatherapy.
Therapeutic grade is the grade used for essential oils that are manufactured from organic sources and suitable for aromatherapy. It can be hard to know the worth of natural herbal compounds and their components only by sight review so it is vital to make purchases only from respected merchants.
