Sweet basil (Ocimum basilicum) is a commonly used spice. The constituent estragole is naturally found in sweet basil and is used in fragrances and flavorings. Although laboratory study has found that estragole may be associated with cancer, human study is lacking.
Laboratory studies have investigated sweet basil for its antiviral, anticancer, and antibacterial effects. However, currently, there is not enough evidence in humans to support the use of sweet basil for any indication.
