Curcumin just as effective antidepressant as Prozac, study concludes
People suffering from depression who take 1000 mg a day of a curcumin-rich extract of Curcuma longa react just as well as they do to a standard dose of 20 mg fluoxetine, the active ingredient in Prozac. Pharmacologists at Government Medical College Bhavnagar in India have written about this in Phytotherapy Research. While we agree that curcumin is a spectacularly interesting substance, we have reservations about this study.
Curcumin
Animal studies, in which researchers simulate depression by exercising animals to the point of exhaustion, have indicated that these remedies may work. They show that curcumin inhibits the enzyme monoamine oxidase in the brain. Monoamine oxidase neutralises neurotransmitters, and administration of curcumin therefore boosts the concentration of serotonin, dopamine and noradrenalin in the brain. [Eur J Pharmacol. 2005 Jul 25;518(1):40-6.]
People suffering from depression not only have reduced concentrations of serotonin and dopamine; their hippocampus also shrinks. The hippocampus is an organ in the brain that plays an important role in the storage and retrieval of information. If the hippocampus is not working so well we store information in a way that it acquires negative connotations and we retrieve it in a negatively coloured way too. Anti-depressants work by enlarging the hippocampus.
Study
The researchers divided their subjects into three groups. One group was given 20 mg fluoxetine every day for six weeks; the second group took one capsule containing 500 mg Curcuma longa extract twice a day, at breakfast and the evening meal; the third group took both substances.
The extract used was BCM-95, produced by Arjuna Natural Extracts. This consists of almost ninety percent curcuminoids, including curcumin, bisdemethoxycurcumin and demethoxycurcumin.
The researchers scored their subjects every two weeks by getting them to fill in a questionnaire based on the Hamilton Depression Rating Scale. A score of 0-7 classifies a person as normal. A score of 8-13 indicates mild depression, a score of 19-22 severe depression, and a score of 23 or higher very severe depression.
Results
Conclusion
"In addition, given the efficacy of curcumin treatment by itself, this study highlights the need for future large-scale clinical trials evaluating the use of this safe and natural dietary botanical as a possible mono-therapy in patients with depressive disorders."
