3. Acts through multiple interrelated mechanisms.

a. can inhibit mitochondrial respiration and reduce peroxide production by upregulating the expression of manganese superoxide dismutase Mn-SOD in the mitochondrial matrix through the activation and expression of the Bcl-2-associated X protein.

b.Astragalus also activates nuclear factor-related factor 2 (Nrf2) to exert its antioxidant effects.

7. application

1、Colon cancer

2、Skin tumor

Astragalus purpureus significantly inhibited NF-κB and activator protein 1 activation-induced skin tumors.

3、Anti-inflammatory

The ability to inhibit the activation of nuclear factor NF-κB, thereby suppressing the activation of pro-inflammatory cytokines and nitric oxide synthase genes, leads to a decrease in the secretion of tumor necrosis factor α, interleukin 1β, interleukin 6 and nitric oxide, thereby reducing the inflammatory stimulatory response.
