Found in the roots of the Curcuma longa plant and a member of the ginger family, turmeric has been used as a medicine, spice (curry) and yellow dye since 600 B.C.
The golden spice has long been used in both Ayurveda and Chinese medicines as an anti-inflammatory agent and used for conditions such as arthritis. It has been highly valued by those who practice Hatha Yoga, for its beneficial effects on ligaments. Throughout Asia, turmeric has been used for stomach problems, allergies, diarrhea, heartburn, wind, bloating, colic, flatulence and liver ailments.

For thousands of years Eastern medicine has used curcumin (the major component of turmeric) for a wide range of health benefits, but only in recent times has its biological action been understood. A wealth of scientific data shows curcumin has powerful anti-inflammatory, anti-tumor and antioxidant properties
Extensive research shows curcumin is effective in multiple ways, and this provides basis for many applications. But curcumin is extremely difficult to absorb, so it's important to get more of it into your bloodstream.

What is Curcumin ?
Curcumin is the yellow-orange pigment and the most important ingredient in turmeric. Curcumin is the most important active ingredient in turmeric, and makes up about 2-6% of the spice. While therapeutic properties of turmeric have been known for centuries, modern science has identified the curcuminoids (phenolic compounds found in turmeric) and provides a scientific basis for many clinical uses of standardized curcumin.
Composition of Turmeric:
Curcumin (curcuminoids) 2-6%
Volatile (essential) oils 3-7%
Fiber 2-7%
Mineral matter 3-7%
Protein 6-8%
Fat 5-10%
Moisture 6-13%
Carbohydrates 60-70%

Extensive research shows curcumin can benefit multiple targets in your body and provides scientific basis for its effectiveness in a wide variety of different body systems

Benefits / uses

Possible Side effects / Precautions / Possible Interactions:
Safety evaluation studies show curcumin is well tolerated at very high doses without any adverse effects. For centuries, curcumin has been consumed as a dietary spice at doses up to 100 mg per day. Recent human clinical trials found no toxicity and no adverse side effects in curcumin when administered at doses of 8,000 milligrams per day for three months.

CAUTIONS: Use during chemotherapy should only be performed under the direct supervision of a qualified medical practitioner. Caution is advised in patients with bleeding disorders or taking drugs that may increase the risk of bleeding. Dosing adjustments may be necessary. Curcumin should be stopped prior to scheduled surgery.

Reported adverse reactions have been limited to mild gastrointestinal distress, which may be minimized by consuming curcumin with food.
