Percolation involves slowly passing a solvent or menstruum through powdered herb material. Percolation is a quick and efficient method of making high quality herbal extracts from dried plant material and allows for achieving 1:2 ratios of dried herb to menstruum, something which may be more difficult to achieve using maceration as an extraction method.

The entire process of percolation may be completed in hours, in contrast to maceration which may take 2 - 4 weeks to complete. 

Percolation is an extremely cost effective way to produce tinctures - for example 250g of Australian grown certified organic Dandelion root which costs $18.00 will yield 500mL of 1:2 organic tincture. Percolation also allows for the production of small quantities of less frequently used herbs, allowing you to expand your dispensary without the worry of expiry dates.
