Turmeric tissue staining for histology and bioimaging
The vibrant color of turmeric has made it useful since ancient times as a cooking spice and clothing dye. There has been much interest in researching it’s potential as a disease therapy. This research focus has prompted labs to apply this low cost, non-toxic substance to tissue staining (1) and bioimaging (2) studies. While turmeric has not been certified by the Biological Stain Commission just yet, studies have demonstrated some good potential to replace synthetic dyes.
