How Curcumin Functions  In Your Body

Curcumin works at cellular level to target the signalling pathways to perform corrective measures which is why it has potential to  address autoimmune diseases and without giving major side effects unlike the traditional Allopathy drugs which act on specific targets—such as enzymes, receptors, or ion channels—to alter physiological processes.
Modern drugs are highly specific in their action, targeting specific receptors or metabolic pathways. 
Curcumin, a polyphenol, has been shown to target multiple signaling molecules while also demonstrating activity at the cellular level, which has helped to support its multiple health benefits 
Curcumins contain numerous medicinal values including anti-oxidation and anti-inflammation. Curcumins exert antiviral, anti-pulmonary fibrosis, and chronic obstructive pulmonary disease effects.
It may also help in the management of body fatigue/gym exercise-induced inflammation and muscle soreness, thus enhancing recovery and performance in active people as well as sports injury as curcumin helps with ligament wear and tear and also tissue remodelling and rebuilding.

A relatively low dose of the complex can provide health benefits for people that do not have diagnosed health conditions. Most of these benefits can be attributed to its antioxidant and anti-inflammatory effects.
