This product is designed to extract essential oils from plant matter.  The kit consists of a one litre bottle of ‘Organic Oil Extraction Liquid’ a ‘Sontara’ cloth, and instructions.
 
The process involves soaking the plant matter in the extraction oil (for about 12 hours), filtering through the ‘Sontara’ cloth (separating the plant matter and the oil), and then allowing the extraction oil to evaporate-leaving a pure essential oil.
