The term 'Mixed with Extraneous Matter' can be summed up as 'IMPURE'. Impurity is the state of containing elements or substances that are not originally part of a material. It is often used to describe a substance that has been contaminated with foreign materials, such as dirt, dust, or other contaminants. Impurities can also refer to the presence of unwanted chemicals or compounds in a material, such as in food or water. Impurities can have a negative effect on the quality and safety of a material, and can even be hazardous to human health.
