To understand how CurQD works, it helps to look at what’s happening at the immune level – deep inside the gut.
Inflammation is a normal and necessary part of the immune response. In a healthy body, the immune system releases signaling proteins called cytokines to respond to threats and support tissue repair. Once that response has done its job, the immune system naturally settles back into balance.
Sometimes, however, this process becomes dysregulated. Pro-inflammatory cytokines stay active for too long, leading to ongoing inflammation and making it harder for the intestinal lining to recover and maintain its protective barrier.
This is where CurQD plays an important role.
How Indigo Naturalis (Qing Dai) Supports Immune Balance
CurQD contains Qing Dai, a botanical ingredient that includes naturally occurring compounds such as indirubin and tryptophan-derived indoles. These compounds have been studied for their ability to interact with a receptor known as the aryl hydrocarbon receptor (AhR).
AhR receptors are found in areas of the body that interact closely with the environment, including the skin, lungs and intestines. In the gut, the AhR pathway helps regulate immune activity and maintain immune balance (homeostasis).
When indole compounds from Qing Dai activate this pathway, they signal the body to shift away from excessive inflammatory activity and toward regulation and repair.
Activating the AhR Pathway
Activation of the AhR pathway leads to several beneficial downstream effects:
-
Increased production of interleukin-22 (IL-22), which supports intestinal barrier integrity and tissue repair
-
Downregulation of pro-inflammatory cytokines such as IL-6, IL-1, and TNF-α
-
Inhibition of NF-κB signaling, a major driver of ongoing inflammation
-
Overall support for a calmer, more balanced immune environment in the gut
Rather than broadly suppressing immune function, this pathway helps the body restore equilibrium, allowing natural healing processes to take place.
Supporting the Body’s Natural Regulation Systems
Because of its central role in immune balance, the AhR pathway has become an important focus in gut health research. Qing Dai is one of the few natural compounds shown to meaningfully engage this pathway.
CurQD works by supporting the body’s own regulatory mechanisms, helping calm excessive immune signaling, promote tissue repair, and support long-term gut balance from the inside out.
