Curcuma Longa CO2-to extract (organic), DE-ÖKO-013
Product-No.: 094.005
Raw material:

Curcuma longa - Rhizome, dried, from organic farming


By supercritical fluid extraction with natural carbon dioxide, no solvent residues, no inorganic salts, no heavy metals, no reproducible microorganisms [1].


70 - 90 % essential oil containing mainly alpha- and beta-turmerone and ar-turmerone; in addition alpha-phellandrene, alpha-zingiberene, sesquiphellandrene. The extract contains only traces of curcumin.


Traditional Use:

Curcuma is an important seasoning and in traditional Chinese medicine and Ayurvedic medicine, turmeric has been used to aid digestion and in treatment of liver and bile problems, it helps relieve arthritis pain, and regulate menstruation. Today, traditional or folk uses of turmeric include heartburn, dyspepsia, stomach ulcers, gallstones, inflammation, and cancer.

In Cosmetics:

In an animal study curcuma longa (turmeric) essential oil shows in dermal application good efficacy in inhibition of Trichophyton-induced dermatophytosis in guinea pigs [2].

In Food Supplements:

Although the product does not contain the polar curcuminoids, which have the yellow colour, nevertheless the essential oil of curcuma contributes to the therapeutic healing effect since it increases the bioavailability of the curcuminoids [3, 4]. Some promising effects of curcuminoids in clinical trials are treatment of various pro-inflammatory diseases including cancer, cardiovascular disease, arthritis, irritable bowel disease, tropical pancreatitis, peptic ulcer, gastric ulcer, gastric inflammation, atherosclerosis, diabetes, diabetic nephropathy, acquired immunodeficiency syndrome (AIDS). Curcuminoids have also shown protection against hepatic conditions and alcohol intoxication [5].

One or more animal studies or clinical trials of curcuma longa (turmeric) essential oil show efficacy in:

-amelioration of ischemia-induced neurological functional deficits [6].

-neuroprotective activity against cerebral ischemia for treatment of cerebral stroke and other disorders associated with oxidative stress [7].

-inhibition of the development of increased blood glucose and abdominal fat mass in obese, diabetic rats when simultaneously curcuminoids are administered [8].

-treatment of disorders of the respiratory tract, e.g. removing sputum, relieving cough, and preventing asthma [9].

Mechanism of Activity

The essential oil of Curcuma longa has a high concentration of the bioactive turmerones. The turmerones have shown in vitro the following activities: inhibition of NF-?B activation in TPA-induced breast cancer cells [10], inhibition of key enzymes linked to type 2 diabetes [11], anti-inflammatory effects in microglial cells [12], apoptosis of human hepatocellular carcinoma [13], anti-inflammatory effects in amyloid ß-stimulated microglia [14], anti-proliferative and immunomodulatory activities [15], activation of apoptotic protein [16].
