The ancient Egyptians first cultivated lettuce (2680 BC) with an intention of producing oil from its seeds. They also believed that the plant helped improve sexual performance, and promoted love and childbearing in women. The Romans too consumed it for sexual stimulation. On the contrary, the ancient Greeks associated it with male impotency. British women in the 1800s avoided it, as there was a widespread belief that it caused infertility and sterility.

Today, in the twenty-first century, lettuce is widely consumed for the multiple health benefits that it offers. Its high nutritional value makes it one of the 10 most popular vegetables grown in American gardens. There exist several types of butterhead lettuce, one of which is butter lettuce. This is preferred for its delicate, mild, and sweet flavor. It looks like a cabbage, and hence, is sometimes called 'cabbage' lettuce. It is also known as 'Boston' or 'Bibb' or 'Boston Bibb' lettuce.
The scientific name of lettuce is Lactuca sativa. It is an annual plant that belongs to the sunflower family 'Asteraceae'. Butter lettuce has a small round head. The buttery soft leaves are arranged loosely. The combination of 'crispy and crunchy' stems and 'soft and tender leaves' makes it one of the most sought-after salad greens.
Lettuce is most often grown as a leaf vegetable. The leaves are used in salads, sandwiches, wraps, and soups. They blend well with other greens, vegetables, meats, and cheese, and help enhance the taste of the dish. One can consume the stems either raw or cooked.
