When sourcing essential oils for therapeutic use, quality and purity are paramount. Below are key considerations to ensure you select oils that meet the highest standards for professional practice.

1. Botanical Names
Always ensure that the essential oils you source include the correct botanical name/species of the plant. This is crucial for distinguishing between different species and chemotypes that may have different therapeutic properties. For example, Lavandula angustifolia (true lavender) differs from Lavandula latifolia (spike lavender), with the latter having different applications and contraindications and one not being safe for pregnancy or childbirth. The botanical name should always be clearly displayed on the label or product description along with the common name to avoid any confusion or misuse, ensuring you are sourcing the correct species for therapeutic use.
2. Organic Oils
For therapeutic use, it’s essential to source organic essential oils. Organic certification ensures that the plants were grown without synthetic pesticides or fertilisers, which can be harmful and compromise the therapeutic qualities of the oil. Organic oils not only preserve the integrity of the plant's natural properties but also support sustainability in farming practices. Look for certifications from recognised bodies, such as USDA Organic, Soil Association, or ECOCERT, to ensure authenticity and adherence to high standards of purity.

3. Focus on Quality
High-quality essential oils are typically sourced from reputable suppliers that prioritise the origin of the plant, its harvesting methods, and the distillation process. Pay close attention to:
Geographic Origin: Some plants thrive in specific climates or regions, which can greatly affect the quality of the oil. For instance, lavender grown in the Mediterranean will have different qualities from lavender grown in other regions.
Extraction Method: Cold-pressed oils (for citrus) and steam-distilled oils (for most plants) should be prioritised. Avoid chemically extracted oils as they may contain solvent residues.
Testing: Reputable suppliers often provide GC/MS reports (Gas Chromatography/Mass Spectrometry) that detail the chemical composition of the oil, ensuring its purity and therapeutic potential.
4.Packaging for Longevity
Essential oils are sensitive to light, heat, and oxygen. To maintain their potency:
Choose oils that come in dark glass bottles (amber, cobalt blue or miron), which help protect the oil from UV light exposure that can degrade the quality of the oil. Opt for bottles with a dropper orice. This prevents too much air from entering the bottle, reducing oxidation and helping to preserve the oil's therapeutic qualities over time.
Essential oils are highly concentrated, and using a smaller bottle size (5ml or 10ml) is ideal to ensure longevity and prevent degradation. Remember oxidised essential oils can be toxic and safety is a number one priority when using essential oils for therapeutic clinical use. These sizes are also practical for regular use while ensuring the oil stays fresh.
5. Supplier Transparency
Always work with suppliers that provide transparency about their sourcing, farming practices, and distillation methods. A reputable supplier will be able to trace the oil back to its origin and offer detailed information about how it was grown and produced. By focusing on these aspects, you will ensure that the essential oils used in therapeutic practice are of the highest quality, safe, and effective for clients and patients.
