Hemoboost is a registered natural product containing specially processed haemolysed
haemoglobin and iron dextran. It is marketed for human use on the basis of many years' use
and documented effect in veterinary medicine. Iron dextran was introduced for use in human
medicine in 1954.
Krauterblut is a registered natural product made from a number of herbs where the active
substance is ferrous gluconate. Both drugs have been available for a number of years and have
become increasingly popular among patients and healthcare staff due to a reduction in adverse
effects.
The objective of this study is to determine the effect and adverse effects of the natural
products Hemoboost and Kräuterblut compared with the usually administered ferrous sulphate in
knee arthroplasty.
