The invention relates to apparatus and a method for the improving the extraction of one or more components from a plant material when adding a liquid to the plant material which is either hot, cold or mid- temperature so as to cause the extraction of the one or more components. During, or after, the addition of the liquid, the liquid is exposed to electromagnetic signals at one or a range of frequencies and, in one embodiment, the said signals are provided in a pulsed manner such that there are periods of electromagnetic frequency signals being generated and periods where there are. not. This is found to enhance the extraction of the one or more components. In one embodiment the liquid is water and is added to the plant material to create a beverage such as a tea or infusion. In one embodiment the electromagnetic emitting means can be suitably design or controlled apparatus and, in one embodiment, is a smartphone, tablet or similar device with a controlling app thereon.
