There are very few situations in which mistletoe therapy is not indicated:
Even if an allergy-like ("pseudoallergic") reaction occurs this does not mean that you do not generally tolerate the mistletoe. The doctor can then choose a preparation with a very low concentration and slowly increase it.
So far, no effects have been reported that would argue against use during pregnancy and lactation.
