different extracts from jojoba plant are widely used in many folk medicinal uses. The aim of the present work was to
make an in-depth pharmacognostic study (both macro- and micro-morphological) in order to help in the
identification and standardization of S. chinensis waxes and extracts. All the microscopical measurements of
different elements and the numerical values of the leaves are listed.
