Cochineal dye is a natural colorant derived from the crushed bodies of the female cochineal insect, primarily found on cacti in Central America and South America. This dye produces vibrant shades of red and is often used in textiles, cosmetics, and food products. The use of cochineal dye dates back to ancient civilizations, including the Aztecs and Mayans, who valued it for its rich color and durability. Today, it is recognized as a safe and effective alternative to synthetic dyes, although some people may have allergic reactions to it.
