Ash Gourd

Known by several other names like winter melon, wax gourd, white gourd, winter gourd, ash pumpkin, white pumpkin and more. In India it is called safed petha and Kashiphal, but, more commonly as, petha kaddu.

Ash gourd was and is traditionally grown in India, Japan, and South-east Asia although it is native to China. "Raja Nighantu" one of the ancient Indian books on therapeutic describes a long list of medicinal benefits of this plant.

Ash Gourd Fruit

Ash gourd is an annual, crawling and climbing vine, grown for its oblong to round very large waxy skinned, pale green-colored fruit with white mild-tasting pulp and yellowish-brown seeds and can weigh over 40 pounds and a foot long if allowed to grow.

The fruits are hairy when young with the coating getting waxy and whitish as they mature although the skin remains green in color culminating in a whitish bloom that occurs only on the fully mature fruit. This bloom enhances the keeping quality of the fruit.

The immature fruit is prepared into a curry, made into a soup and the pulp ground to extract its health-promoting juice.

The mature fruit is used to make petha, an Indian candied sweet, a type of soft translucent candy which was first prepared in the Indian city of Agra.

In Indian cuisine, ash gourd is used to make a variety of dishes like stir-fries, stews, and soups. The younger leaves, stems, and buds are also cooked.

Since its juice is bland in taste it is not consumed widely in spite of its excellent nutritive and therapeutic value.

Ash gourd has been used both as a food and medicine for thousands of years in the Orient Traditional Oriental medicine has used it to treat respiratory, gastro-intestinal, heart and urinary issues, diabetes and as a vermifuge.

The Nutritional Benefits of Ash Gourd

Over 95% of ash gourd's weight is water, the carrier of several vitamins and minerals, making it a natural energizing food. It is low in calories, contains no saturated fat or cholesterol. It is a good source of thiamine, iron, magnesium and manganese and a very good source of dietary fiber, vitamin C, riboflavin and zinc. However, it is a little high in sodium.

Since it reduces body heat and cools the body it can be added to salads, smoothies, and juices in the summer months. The seeds and seed oil too are equally beneficial. In Southeast Asia, winter melon tea is very popular.

Ash gourd is easy to digest and balances the Pitta and Vata doshas of the body. It especially improves intelligence.

The uncut fruit stores well for a long time, in fact as long as a year without refrigeration.
