Malachite green is a synthetic dye that is primarily used in various industries, including textiles and aquaculture. It is known for its vibrant green color and is often used to color fabrics and as a biological stain in laboratories. In aquaculture, it has been used to treat fungal infections in fish, although its use has become controversial due to potential health risks. In addition to its industrial applications, malachite green has been studied for its antifungal and antibacterial properties. However, concerns about its toxicity and potential carcinogenic effects have led to restrictions on its use in food-producing animals and certain consumer products, prompting a search for safer alternatives.
