The Science and Art of Cold Percolation


I would like to take this opportunity and explain about the laboratory at ICNH-TCM and to elaborate on the processes utilized in the manufacturing of modern herbal medicine used and taught at the school.

The ICNH-TCM laboratory us ultra modern and uses a patented process called “Cold Percolation” which produces and herbal product that is known as a “Full Spectrum” tincture.

To elaborate on each term, cold percolation is the name for an extraction made at a temperature of 60 degrees “C” or less. Full spectrum is the term used to denote the fact that all the “Active principles” (The medicinal part of the plant material) have been extracted for a patient.

The usual method for herbal medicine making is called “Maceration” a very old system in use for 250 years that is usually a 14 – 38 day process from start to finish. COLD PERCOLATION ACCOMPLISHES THE extraction from the plants in a period of only 8 hours and in spite of the short time, the quality of the extraction is between 40% and 500% more efficient.

The reason for the increase in quality is the fact that maceration is done at room temperature and cold percolation is done at 50 degrees “C”. Warm solvent is more extractive than solvent at room temp.

The second important feature of the cold percolation systems is the fact the size of the lab percolators is very small compared to the large stainless steel system.

This means that a cold percolation lab utilizes 1/100th, the usual space required for maceration process.

The third important feature is the lack of warehouse room and inventory. In a 38 day process, a great deal of stock is required to address daily requirements. In the case of cold percolation, since you can produce a quality production in 8 hours, there is no need to warehouse a huge inventory since anything can be made up in just a few hours.

Inventory is about 1/10th , of inventory in maceration labs.

The actual cost of the lab equipment is also much less than you would expect.

The lab equipment costs as about 1/10th , the cost of stainless.
