In Greek its name means ‘royal remedy’ or ‘king’. In the 16th century, powdered basil was used to treat migraines and chest infections. The ancient Egyptians believed that it would open the gates of heaven to a dying person, and the Hindus use Basil sprigs to protect the dead from evil while in transition between lives. Western European lore sometimes claimed that it was a symbol of evil, while the Eastern Orthodox Church used it in the making of holy water.

Basil essential oil pairs well with a variety of other essential oils, depending on the intended use. For example, when used for aromatherapy, basil oil blends well with citrus oils such as lemon or bergamot, as well as with floral oils such as lavender or geranium, creating a bright and uplifting aroma. When used in skincare, basil oil can be blended with carrier oils such as coconut or jojoba oil, as well as with other essential oils such as tea tree or peppermint oil, for added cleansing and nourishing properties. In haircare, basil oil can be paired with other essential oils such as rosemary or cedarwood oil, which are also known to promote healthy hair growth and scalp health. Ultimately, the best essential oil pairing will depend on the specific intended use and desired effects.
