In the previous generation, people would visit oil mills with seeds like peanuts, coconuts (dry coppery) sesame seeds, for extract nature oils, for their daily usage for cooking. Those oil mills have produced oils in a natural way using a wooden press. This is called as wood pressed oil. It is also called as cold pressed oil. In Tamil, it is popularly known as mara chekku ennai. But in the last few decades, with the arrival of refined oil, use of wood pressed oil is reduced and it was only used very rarely only in few traditional villages. We extract oils using old traditional Technic for good health.
