Mistletoe tincture is used for multiple issues especially Hypertension, vascular headaches and improving the tonus of the bladder, large intestine or uterus. It is a low dose herb that needs to be used with a certain degree of knowledge. If by “Mistletoe extract” you mean the fermented biodynamic Mistletoe products such as Iscador, Isorel or Helixor, no I do not use them. They are injectables used to treat cancer (herbalists do not use injectable medications).
