MENTHA OIL
Mentha is an aromatic herb, which also goes by the name Japanese pudina in India. Steam distillation and filtration of dried Mentha arvensis leaves produces mentha oil, which can be processed to yield menthol and other derivatives. Mentha oil and its derivatives are extensively used in food, pharmaceutical, perfumery, and flavouring industry.
Mints are aromatic, almost exclusively perennial, rarely annual herbs. They have wide-spreading underground and overground stolons and erect, square,branched stems. The leaves are arranged in opposite pairs, from oblong to lanceolate, often downy, and with a serrated margin. Leaf colors range from dark green and gray-green to purple, blue, and sometimes pale yellow.The flowers are white to purple and produced in false whorls called verticillasters. The corolla is two-lipped with four subequal lobes, the upper lobe usually the largest. The fruit is a nutlet, containing one to four seeds.
While the species that make up the Mentha genus are widely distributed and can be found in many environments, most grow best in wet environments and moist soils. Mints will grow 10–120 cm tall and can spread over an indeterminate area. Due to their tendency to spread unchecked, some mints are considered invasive
