coils of wire with a current going through produce a magnetic field, n at one end and s at the other. There are mats (very expensive) that alternate this current every 2 minutes, so n changes to s and vice versa. Red blood corpuscles contain iron, so are attracted to magnetic poles. The alternating current therefore ends up `straightening` and de-clumping these red corpuscles in the blood stream. This is the holy grail of magnetic field application. Similar can be achieved by stroking with a fixed magnetic field, the corpuscles will align, just like iron filings
Small neodymium magnets are often used as therapy and can be sown into fabric, gloves, panties etc. They are not very expensive, you just have to make something with small pockets to hold them. I used these small magnets many times over my adult lifetime
I did treat myself to a mat, after my husband died, I already knew about them but at that point I did need to reduce the cortisol in my body, fast because of its damaging effects on the body.
