Turmeric (Curcuma longa)is related to ginger and is a major ingredient in Indian curries, and gives many foods a beautiful yellow color. But evidence is accumulating that turmeric has disease-preventive qualities as well, because turmeric contains more than two dozen anti-inflammatory compounds. By itself curcumin (the component in turmeric most often cited for its healthful effects)is a multifaceted anti-inflammatory agent.
Turmeric is also an effective live detoxifier and has been used in Chinese medicine to treat depression. More than 50 studies have found evidence on turmeric's effects in addressing Alzheimer's disease.
Curcumin appears to be universally useful for just about every type of cancer, and has the most evidence-based literature supporting its use against cancer. It has the ability to modulate genetic activity and expression, both by destroying cancer cells, and by promoting healthy cell function.
