Curcumin is an active component of
turmeric, a spice and coloring agent used in curry powder. There has been much interest in using it to treat or prevent a number of different medical conditions, such as
high cholesterol and cancer. There are many other purported uses as well, some of which are more valid than others.
Curcumin may have several different effects in the human body, such as:
- Anti-inflammatory -- Curcumin seems to inhibit several different inflammatory substances and enzymes. This may be helpful for a number of conditions, such as arthritis or heart disease.
- Angiogenesis inhibition -- Curcumin may inhibit the growth of new blood vessels (a process known as angiogenesis). This property may be useful for preventing or treating cancer, but it could cause problems in the treatment of heart disease.
- Blood clotting -- There is some evidence that it may help to prevent blood platelets from sticking together (a process known as platelet aggregation), an important step in the formation of blood clots.
There is also some evidence that it may have antioxidant effects and may stimulate the immune system.
There is not enough evidence to know for sure if it is effective for most uses. Some uses have more scientific evidence in their favor than others
(see Does Curcumin Work? for more information).
The best curcumin dose has not yet been determined
(see Curcumin Dosage for more information).
Even though it is a "natural" product, curcumin can cause side effects, such as nausea and
diarrhea.

What If I Take an Overdose of Curcumin?
It is not known what exactly to expect from an overdose, or even if an overdose is possible. It is reasonable to assume that taking too much may cause the usual side effects, but perhaps more severely.
