Healthcare providers can assess injection technique, review site rotation practices, and consider whether alternative treatment options might be better tolerated

A 2021 review published in Biomedicine & Pharmacotherapy explains that silymarin, the main active compound in milk thistle, can:25 Regulate the cell cycle, helping to ensure proper division and replication Induce apoptosis, or programmed cell death, by which the body can eliminate mutated cells (e.g., cancer cells) Regulate the body's immune response, increasing its ability to recognize and attack cancer cells Keep tumor cells from growing and spreading Inhibit angiogenesis, the process by which tumors create new blood vessels that increase their blood supply and help them grow The review specifically discusses silymarin's therapeutic potential for gastrointestinal cancer, but as another set of researchers note, silymarin has a pleiotropic effect, meaning it can act on multiple targets.26 Again, more research may be needed, but the current science suggests that milk thistle may have fairly broad complementary utility in cancer therapy

Unlike the sharp pain of acute inflammation, chronic inflammation is subtle and ongoing
The magnitude of peak change in the present study is modest as compared to oral administration of tryptophan at 2g or tyrosine at 10g to breastfeeding mothers which may achieve 600% to 700% greater free amino acid levels in the blood plasma of mothers who breastfeed
