Ammi visnaga, commonly known as khella, is a powerful and potent herb which has been used since the time of the ancient Egyptians. The Egyptians made a tea with the fruit of Ammi visnaga and today a tea can still be prepared from a tincture of the plant. The plant khella is related the Queen Anne's Lace (Daucus carota) and it is very similar in appearance. However, it is a lot more potent herb.
Khella essential oil has a deep earthy, slightly floral aroma which pairs well with citrus top note essential oils, or lemon-based essential oils.
