Highly regarded and referred to as "The Plant of Immortality" by early Egyptians, Aloe Vera (Aloe barbadensis) has been used in cosmetic applications. The word "aloe" is derived from the Arabic "alloeh" meaning bitter and shiny substance, referring to the gel or juice that can be squeezed from the leaves. The inner leaf or latex (the part of the plant that grows under the covering or rind) is also used for its beneficial properties. Peppermint (Mentha piperita) is a widely used and universally loved flavoring. So highly thought of that it was included in a list of plants taken to the New World, medicinal interest in mints dates from the first century A.D. Peppermint's value comes from the mint's volatile oil and is added to a variety of products for therapeutic effects.
