Turmeric root has been used in ancient Siddha medicine and by Ayurvedic practitioners for close to 4,000 years as a digestive aid and culinary spice ingredient prepared in curries and cleansing kitcharies.
Although turmeric might seem like quite the ordinary kind of kitchen cabinet seasoning, this inconspicuous rhizome is one of those commonplace foods you wouldn't normally recognize as a superfood. This is often sometimes the case with a number of herbs and spices that have been used throughout the world and human history.
But in fact, turmeric is one of the most extensively researched herbs in the scientific health field, offering a potent source of antioxidant-rich compounds as well as antibiotic, antiviral and antifungal properties.
Consuming turmeric root is a simple and effective way to re-boost immune health and keep us free of disease and sickness. Other evidence suggests its specific usefulness as an anti-inflammatory, helpful as an herbal remedy for aches, muscle soreness, digestive disorders and combating infections.

Turmeric is obviously very high in beta-carotene, an antioxidant great for maintaining healthy eyes and vision, but there are also other active ingredients found in the root and these are referred to as "curcuminoids."
The yellow-orange coloration present in turmeric is the base of one of the major alkaloids in the root called curcumin, one of three curcuminoid phenols. The various healing components of turmeric are attributed to this golden colored antioxidant compound. Curcumin is responsible for its pungent flavor and although it only makes up about 3-4% of the tuber, it is a potent and concentrated source of phytonutrients.
Curcumin has been widely researched in the past 20 years for its proven effects as a powerful anti-inflammatory providing specific relief for those with arthritis, rheumatism and may even be beneficial for reducing amyloid plaque build-up associated with Alzheimer's disease.

(*) In 2013 research finding it states that "Studies have indicated that turmeric oil, present in turmeric, can enhance the bioavailability of curcumin."
Turmeric root is widely cultivated in India and often conventionally grown with the use of heavy pesticide sprays and synthetic fertilizers.

Curcumin is similar in nature to other polyphenol plant pigments like anthocyanins found in various berries like acai, maqui and blueberries, the phycocyanin in blue green algae as well as the betanin found in beetroots.
Curcumin is one of three active "curcuminoids" found in the rhizome with the other two being desmethoxycurcumin and bis-desmethoxycurcumin.
Although there has been lot of attention given to curcumin in the past 10 years, there is also some recent evidence that curcumin is not exclusively the chief component to turmeric's health enhancing attributes as once believed.
In the 2013 issue of Molecular Nutrition and Food Research, a curcumin-free turmeric was tested for potency as a potential anti-inflammatory. The publication reveals that "Studies over the past decade have indicated that curcumin-free turmeric (CFT) components possess numerous biological activities including anti-inflammatory, anticancer and antidiabetic activities."

"High-fat diets and increased blood cholesterol are linked to increased amyloid plaques by the intracellular accumulation of cholesterol esters. Researchers believe that by inhibiting cholesterol formation and decreasing serum peroxides, curcumin might exert beneficial effects on Alzheimer's Disease (AD)." (Source)
Many health authorities also agree that coconut oil may also be helpful for Alzheimer's patients as it offers an alternative ketone energy fuel for the brain. Both the oil and turmeric can be used together as a natural home remedy and dietary supplement.
India is known to have a much lower incidence of Alzheimer's than those in the United States, who eat less turmeric and curry dishes.
Recently published documentation in the Journal of Indian Academy of Neurology analyzing the effects of turmeric on Alzheimer's patients it states that "Various studies and research results indicate a lower incidence and prevalence of AD in India. The prevalence of AD among adults aged 70-79 years in India is 4.4 times less than that of adults aged 70-79 years in the United States." (*)
One of the less talked about top health benefits of turmeric root is actually as a liver cleanser and blood tonic.
