What is an concrete?
Concrete are prepared almost exclusively from raw materials of vegetable origin, such as the bark,flower,leaf,herb or root. The aromatic plant material is subjected to extraction by hydrocarbon-type solvents. The solvent dissolves all extractable matter from the plant which includes non-aromatic waxes, pigments and highly volatile aromatic molecules. The remaining waxy mass is what is called the concrete.
A concrete is the concentrated extract that contains the waxes and/or fats as well as the odoriferous material from the plant.
