An article sticking to the nuts and bolts of the biology is probably unnecessary. This is exactly what you would expect: toxins are in the blood. Blood is removed at a blood donation. Ergo, donating blood will naturally remove some toxins. The fresh new blood your body makes is naturally toxin-free.
A more interesting and rich exploration would be how it is that ancient people "knew" that bloodletting worked, long before we had microscopes and cell biology...
The blood donation thing is pretty wild. Would be interested in a deeper dive on that.
