BPT has a number of actions that have been shown to significantly reduce viral load.  Those being:

• Attacking infections that are within the blood
• Improving the function of the blood, rheological improvements, i.e. blood flow, carrying capacity and increased red blood cell production
• Increases the activation of circulating IgM and IgG which are non specific immune factors
• Increases surface antibodies on red blood cell membrane
• Provide an auto vaccine for specific strains of virus
