Electromagnetic radiation is all around us, though we can only see some of it. All EM radiation (also called EM energy) is made up of minute packets of energy or 'particles,' called photons, which travel in a wave-like pattern and move at the speed of light. The EM spectrum is divided into categories defined by a range of numbers.
Externally, marshmallow root is very useful in the form of poultice, to discuss painful, inflammatory tumors, and swellings of every kind, whether the consequence of wounds, bruises, burns, scalds, or poisons; and has, when thus applied, had a happy effect in preventing the occurrence of gangrene.
The use of marshmallow to make sweets dates back to ancient Egypt, where the recipe called for extracting sap from the plant and mixing it with nuts and honey. Another pre-modern recipe uses the pith of the marshmallow plant, rather than the sap.The stem was peeled back to reveal the soft and spongy pith, which was boiled in sugar syrup and dried to produce a soft, chewy confection. The marshmallow plant's sap was also used by gladiators in ancient Rome.arshmallow probably came first into being as a medicinal substance, since the mucilaginous extracts come from the root of the marshmallow plant, Althaea officinalis, which were used as a remedy for sore throats.
