Curcumin has antioxidant, anti-inflammatory,  antiviral and antifungal actions.  Studies have shown that curcumin is not toxic to humans. Curcumin exerts anti-inflammatory activity  by inhibition of a number of different molecules that play an important role in inflammation.

Turmeric is effective in reducing post-surgical inflammation.  Turmeric helps to prevent atherosclerosis by reducing the formation of bloods clumps.

Curcumin inhibits the growth of Helicobacter pylori, which causes gastric ulcers and has been linked with gastric cancers.

Curcumin can bind with heavy metals such as cadmium and lead, thereby reducing the toxicity of these heavy metals.

This property of curcumin explains its protective action to the brain. Curcumin acts as an inhibitor for cyclooxygenase, 5-lipoxygenase and glutathione S-transferase.

Turmeric is generally safe. It can cause nausea and diarrhea, especially in high doses or after long-term use. It might also pose a risk of ulcers in high doses. As a topical treatment, it can cause skin irritation.

Caution is advised when turmeric is taken by people known to have gallstones; consult your health care provider first.

For any systemic purpose (requiring absorption from the intestines), then an oral supplementation of curcumin in the range of 80-500mg would be required assuming an enhancement. If one of the above enhancements are not used, then too little curcumin will be absorbed and even doses of up to 4,000mg may be wholly inactive (8-16g would only be slightly active). If using curcumin for intestinal purposes, then absorption from the intestines into the blood is not necessarily required. Due to this, one can simply use

Turmeric at the dose of 2-4g daily or take curcumin  supplementation without any of the aforementioned enhancements.
