My wife has arthritis and swears by a supplement called Devils Claw. I don’t like the sound of it how can I persuade her to stop?

I agree that devils claw does sound fearsome, however you have nothing to worry about.

Devils Claw is the name given to a plant with claw shaped tuberous roots. The roots are rich in a natural glycoside substance which has been shown to have a powerful anti-inflammatory effect on some people. It is always wise to consult your GP before embarking on supplements but in most cases he or she would say to anyone taking it “it can’t do you any harm and if it makes you feel better then carry on”.
