- Alkanna is grown in the south of France and on the shores of the Levant (the mountainous region paralleling the eastern shore of the Mediterranean, including parts of the countries of Turkey, Syria, Lebanon, and Israel). Its root yields a fine red coloring, which has been used as a cloth dye and a tint for tinctures, oils, wines, and varnishes. It is commonly used today as a food coloring.
- Alkanna has been used traditionally for its wound healing and anti-inflammatory effects. Evidence supporting folkloric uses of alkanna is mixed.
- There is currently no available scientific evidence of alkanna to recommend its use, safety or effectiveness for any medical condition.
