Time wise, it has taken as long as nine weeks to know when the perfect ratio, of just the right oils, has been reached.
Blending is done one drop at a time and sitting intervals must be taken to allow the oils to 'marry'. A synergy develops between the individual oils and, when the process is complete, an entirely new oil emerges as the blend. Individual therapeutic qualities are combined, as well as scent, and the result is a unique, one of a kind oil. The last step is deciding what to name it.
I use only 100% pure essential oils, of the highest quality and therapeutic value. Extraction methods are cold pressing or steam distillation. A prerequisite, of each batch I source, is that the GC Analysis certifies the oil as being free from solvents, dilutions and contaminants of any kind.
