คำศัพท์Rosemary (Rosmarinus officinalis L.) is a perennial herb with fragrant
evergreen needle-like leaves. It is native to the Mediterranean
region and it has been cultivated for a long time. It belongs
to the Lamaiaceae family, which comprises up to 200 genera and
about 3500 species. The leaves are evergreen, with dense short
woolly hairs. Rosemary has been a significant herb since antiquity,
although rosemary is more familiar to contemporary Westerners
as a kitchen herb used to add a spicy or slightly medicinal flavour
to some foods, it was traditionally used as an antiseptic, astringent,
and food preservative before the invention of refrigeration. เฉพาะทางเคมี
