    Mistletoe Extracts (PDQ®): Complementary and alternative medicine - Health Professional Information [NCI] - Adverse Effects

    Although a number of different mistletoe extracts have been used in human studies, the reported side effects have generally been minimal and not life threatening. Common side effects include soreness and inflammation at injection sites, headache, fever, and chills.[1,2,3]

    One meta-analysis using Viscum album L. and isolated mistletoe lectins included both animal and human studies. Doses and application forms varied. No immunosuppressive effects were reported. Side effects included local reactions at the injection site and flu-like symptoms such as fever, chills, fatigue, mild gastrointestinal symptoms, and headache. High doses of mistletoe lectins resulted in reversible hepatotoxicity in some cases.[4] Another review reported adverse reactions that included local reactions at the injection site, fever, increased intracerebral pressure, headache, circulatory problems, thrombophlebitis, swelling of lymph nodes, and allergic reactions.[5]
