Clinical Bottom Line/Effectiveness
Brief Background:
- Alizarin is a histochemical stain that highlights calcium. It is used by dermatopathologists to detect dermal calcium in disorders such as pseudoxanthoma elasticum and calcinosis cutis (1).
- Originally alizarin vegetable dye was prepared from the madder plant Rubia tinctorum, but now a synthetic preparation is used which is chemically identical.
- There are no well-established therapeutic uses of alizarin other than as a bone-marker or staining agent. However, one study investigated alizarin in the treatment of viral infections (2).
- Precautions should be taken while handling this dye due to the unavailability of sufficient safety data (3).
