Euryale ferox (also known as fox nut, foxnut, makhana, or gorgon plant) is the only species in the genus Euryale. It is a flowering plant classified in the water lily family, Nymphaeaceae, although it is occasionally regarded as a distinct family Euryalaceae. Unlike other water lilies, the pollen grains of Euryale have three nuclei.[1]

Contents

Growth

Euryale is an annual plant native to eastern Asia, and is found from India to Korea and Japan, as well as parts of eastern Russia.[2] It grows in water, producing bright purple flowers. The leaves are large and round, often more than a meter (3 feet) across, with a leaf stalk attached in the center of the lower surface. The underside of the leaf is purplish, while the upper surface is green. The leaves have a quilted texture, although the stems, flowers, and leaves which float on the surface are covered in sharp prickles. Other leaves are submerged.

Uses

Food uses

The plant produces starchy white seeds, and the seeds are edible. The plant is cultivated for its seeds[2] in lowland ponds in India, China, and Japan. The Chinese have cultivated the plant for over 3000 years.[3] More than 96,000 hectares of Bihar, India, were set aside for cultivation of Euryale in 1990-1991.[4] The plant does best in locations with hot, dry summers and cold winters. Seeds are collected in the late summer and early autumn, and may be eaten raw or cooked.

In India, particularly in the northern and western parts of the country, Euryale ferox seeds are often roasted or fried, which causes them to pop like popcorn. These are then eaten, often with a sprinkling of oil and spices. In Mithila culture of Bihar, India, the makhana is an auspicious ingredient in offerings to the Lord during festivals and is used in cooking, specially to make a porridge/pudding called kheer of makhana or 'makhane ki kheer'.

Evidence from archaeobotany indicates that Euryale ferox was a frequently collected wild food source during the Neolithic period in the Yangtze region, with large numbers of finds coming from the sites of Kuahuqiao, Hemudu, and Tianluoshan [5]

Medicinal uses

In Chinese, the plant is called qiàn shí (simplified Chinese: traditional Chinese: ).[2] Its edible seeds are used in traditional Chinese medicine, where they are often cooked in soups along with other ingredients, and believed to strengthen male potency and retard aging.[2]

Etymology

The name Euryale comes from the mythical Greek Gorgon by the same name. The Soviet Union issued a postage stamp featuring this species.
