Basil (Ocimum basilicum) (IPAEng: ˈbæzəl or /ˈbeɪzəl/), of the Family Lamiaceae, is a tender low-growing herb.

Basil is a culinary herb prominently featured in Italian cuisine, and also plays a major role in the Southeast Asian cuisines of Thailand, Vietnam and Laos. The plant tastes somewhat like anise, with a strong, pungent, sweet smell.

There are many varieties of basil. That which is used in Italian food is typically called sweet basil, as opposed to Thai basil, lemon basil and holy basil, which are used in Asia. While most common varieties of basil are treated as annuals, some are perennial in warm, tropical climates, including African Blue and Holy Thai basil.

Basil is originally native to Iran, India and other tropical regions of Asia, having been cultivated there for more than 5,000 years.

Etymology

The word basil comes from the Greek βασιλεύς (basileus), meaning "king", as it is believed to have grown above the spot where St. Constantine and Helen discovered the Holy Cross. The Oxford English Dictionary quotes speculations that basil may have been used in "some royal unguent, bath, or medicine". Basil is still considered the "king of herbs" by many cookery authors. An alternative etymology has "basil" coming from the Latin word basilicus, meaning dragon and being the root for basilisk, but this likely was a linguistic reworking of the word as brought from Greece.

Culinary use

Basil is one of the main ingredients in pesto—a green Italian oil-and-herb sauce. Its other two main ingredients are olive oil and pine nuts.

The most commonly used Mediterranean basil cultivars are "Genovese", "Purple Ruffles", "Mammoth", "Cinnamon", "Lemon", "Globe", and "African Blue". The Chinese also use fresh or dried basils in soups and other foods. In Taiwan, people add fresh basil leaves to thick soups (羹湯; gēngtāng). They also eat fried chicken with deep-fried basil leaves. Basil (most commonly Thai Basil) is commonly steeped in cream or milk to create an interesting flavor in ice cream or chocolates (such as truffles).

Basil is sometimes used with fresh fruit and in fruit jams and sauces—in particular with strawberries, but also raspberries or dark-colored plums. Arguably the flat-leaf basil used in Vietnamese cooking, which has a slightly different flavour, is more suitable for use with fruit.

Basil seeds

When soaked in water the seeds of several basil varieties become gelatinous, and are used in Asian drinks and desserts such as falooda or Sherbet. Such seeds are known variously as sabza, subza, takmaria, tukmaria, falooda, selasih (Malay/Indonesian) or hột é (Vietnamese). They are used for their medicinal properties in Ayurveda, the traditional medicinal system of India.They are also used as popular drinks in Southeast Asia.
