Eggplant health benefits and therapeutic value


Eggplant, or Solanum melongena, belongs to the Solanaceae or nightshade family. Its smooth-skinned fruit is the star of the Mediterranean diet.

This plant native to India can grow up to 40 to 60 inches (100 to 150 cm) tall.

There are incredibly many different varieties of eggplants, with many different shapes and colors.

The most common is the ‘Barbentane’ variety, which has a cylindrical shape and traditional dark purple color. But there are also white ones, striped white and purple ones, black ones and yellow ones.

China and India are the world’s two largest eggplant producers.

Eggplant, a short story

Native to India, eggplant moved to China 4 centuries before Christ. It then spread to Europe thanks to the Arabs, but not before the XIIth century.

Even though, it took time for eggplant to be appreciated. Indeed, people feared eating eggplant because they thought it would induce fever or epilepsy bouts. People thought it was toxic because it was very close in appearance to a toxic plant: mandragora, which also belongs to the Nightshade family.

Thus, eggplants were only used for its medicinal properties, especially in poultices against hemorrhoids.
