Q. What is curcumin?
A. Curcumin is a component of an Indian spice, turmeric. It is estimated that 100 grams of
turmeric contains 3-5 gram curcumin. Curcumin gives a yellow color to turmeric, also
present in curry powder. Chemically, curcumin is called diferuloylmethane. Curcumin is
yellow-orange in color. Curcumin is used as a natural yellow coloring in mustard,
cereals, cheese, and butter. In some countries, it is used as a natural coloring agent in
the textile industry.
Q. When was curcumin isolated?
A. Curcumin was isolated from the spice turmeric, as one of the active principle, more
than 100 years ago.
Q. What does curcumin do?
A. The activity of curcumin has been demonstrated against cancer, cardiovascular
diseases, type II diabetes, Crohn’s disease, psoriasis, atopic dermatitis, arthritis etc.
Q. How does curcumin work?
A. Turmeric has been described in Ayurveda (An Ancient Indian System of Medicine;
means long life) as an agent that can suppress inflammation. An extensive research
during last 50 years has revealed that the anti-inflammatory activity of turmeric is due
to curcumin. Curcumin can inhibit both the activity and the synthesis of
cyclooxygenase-2 and 5-lipooxygenase; and other enzymes that have been implicated in
inflammation. Curcumin has also been shown to work through numerous other
mechanisms. More than 700 genes have been shown to be modulated by curcumin.
Q. Does curcumin work against cancer?
A. Curcumin has been shown to prevent a large of number of cancers in animal studies.
Laboratory data indicates that curcumin can inhibits tumor initiation, promotion,
invasion, angiogenesis and metastasis.
Epidemeological evidence indicate that incidence of certain cancers are less in people
who consume curcumin than those who do not. Recent evidence indicates that, besides
chemopreventive activity, curcumin may also be effective in the treatment of cancer.
Q. How does curcumin work against cancer?
A. Numerous mechanisms have been described for the anticancer activity of curcumin.
Inhibition of proliferation of tumor cells, induction of apoptosis (a mode of cell death),
inhibition of transformation of cells from normal to tumor, invasion of invasion and
metastasis and suppression of inflammation, have been linked with the anticancer
activity of curcumin. Downregulation of COX2, 5-LOX, adhesion molecules,
inflammatory cytokines, chemokines, growth factor receptors, VEGF, and transcription
factors by curcumin have been linked to its antitumor activity.
Q. Does curcumin work against arthritis?
A. Arthritis is also a proinflammatory disease. All current drugs approved for arthritis
have anti-inflammatory activity. Anti-TNF therapy has been approved for this disease.
Curcumin has been shown to both suppress the TNF production as well as block the
action of TNF. Curcumin, when applied topically, has been shown to have activity
against arthritis.
Q. Does curcumin work against Crohn’s disease (inflammatory bowl disease)?
A. Crohn’s disease is also a pro-inflammatory disease. All current drugs approved for this
disease have anti-inflammatory activity. Anti-TNF therapy has been approved for this
disease. Curcumin has been shown to both suppress the TNF production and the TNF
action. Curcumin, taken orally, has been shown to have activity against Crohn’s disease.
Q. Does curcumin accelerate wound-healing?
A. There is numerous experimental data that suggest that curcumin can accelerate wound
healing. This has lead Johnson & Johnson to supply curcumin-containing band-aid.
Q. Does curcumin work against Psoriasis?
A. Psoriasis is another proinflammatory disease. Numerous evidence, both in animal and
human, indicate that curcumin is quite effective against Psoriasis when applied topically
to the skin.
Q. Does curcumin work against Alzheimer disease?
A. Because Alzheimer disease is caused in part by amyloid-induced inflammation,
curcumin has been shown to be effective against Alzheimer. Clinical trials are in
progress in UCLA with curcumin for Alzheimer.
Q. Are there any human clinical trials done with curcumin?
A. There have been at least ten different clinical trials performed with curcumin in patients
with different diseases. These are mostly pilot studies that are “proof of concept” type.
More than ten trials are now in progress in the United States and other countries.
Q. Has there been any toxicity associated with curcumin?
A. According to one of the Phase I study, curcumin was found to be safe in human
subjects even when consumed up to 8 grams per day for three months. Inspite of it,
one is recommended to take low dose 500 mg/day to higher dose if needed gradually.
Look for signs of both potential toxicity and improvement by talking to your body and
to your doctor.
Recommendations for Cancer: If you have cancer, please consider curcumin for
yourself as following regimen:
1 g/day for week one; if no side effects then,
2 g/day for week two; if no side effects then (can be split into three separate doses).,
4 g/day for week three; if no side effects then (can be split into three separate doses).,
8 g/day for week four; for eight weeks (can be split into three separate doses).
By then, a significant improvement is expected.
If you do not have cancer then one capsule (500 mg) per day is sufficient.
Q. How should I take curcumin?
A. There are reports to indicate curcumin taken empty stomach is more effective than with
the meals. Thus it is recommended that you take curcumin 1 h before meals. If you are
taking curcumin powder (instead of capsule), you can take it with milk, yogurt, coconut
milk or other fluids.
Q. Where do I buy curcumin?
A. Although there are numerous companies that supply curcumin, one need to be careful
that you are buying genuine product.

Q. Where do I read more about it?
A. Please refer to the following articles.
