Artemisinin iron cancer

 My brother has terminal cancer. Hospital said nothing else they can do. Feeding tube formula they had him on was horrible and he couldn't keep it down. I sourced an organic real food formula (Functional Formularies) and it's working great. Tested his iron and it is low. I started him on liquid iron supplement Tues (Oct 17) and want to start Artemisinin (4 days on 3 days off) on Friday. Does he need to continue taking the iron the 4 days he's taking Artemisinin or stop the iron the days he's taking Artemisinin. Thank you
