Abstract: The present disclosure relates generally to a therapeutic system and method to manage and modulate inflammation by reducing inflammation with enhanced anti-inflammatory measures. Using a light source such as light emitting diodes (LEDs) or a laser light source, the photons can be used to applied to increase the efficacy of medicine on the organ (i.e., disease site) that needs treatment by imparting the light rays only to the site rather than the whole body. The photons produced by the light source increase adenosine triphosphate (ATP) to improve the functional selectivity of G Protein-Coupled Receptors (GPCR). With the increased efficacy of medicines to the disease site, the dosage of medicine can be reduced to minimize the side effects in particular to other parts of the body. The treatment may be used to treat inflammation caused by corona virus of 2019 (COVID-19) infection.
