European Mistletoe Leaf Extract
Also known as: European Mistletoe, Mistletoe, Viscum album
Overview
European Mistletoe Leaf Extract, derived from the leaves of *Viscum album*, has long been used in folk medicine. It serves as a complementary therapy, especially for cancer patients, helping to enhance quality of life and alleviate cancer-related fatigue. This extract contains immunomodulatory lectins, which are the focus of current research. While evidence is accumulating through systematic reviews and meta-analyses, the quality of studies often varies due to bias and methodology issues. *Viscum album* is available in various forms, primarily as injectable extracts, aimed at improving the health and well-being of individuals undergoing cancer treatment.
Benefits
Evidence suggests several benefits of European Mistletoe Extract for cancer patients. Notably, it has been linked to improved quality of life, particularly in those with breast cancer, with studies reporting a medium effect size similar to other therapeutic interventions. Additionally, mistletoe extracts may help reduce cancer-related fatigue, as illustrated by a moderate effect size (SMD = -0.48, 95% CI -0.82 to -0.14) in various clinical trials. Despite potential survival benefits indicated by meta-analyses, the evidence here is mixed and often confounded by methodological weaknesses. Thus, while breast cancer patients may especially benefit from these effects, overall clinical significance remains a subject of ongoing investigation.
How it works
European Mistletoe Extract is believed to positively influence the immune system through its lectin constituents, which can stimulate the production of cytokines and activate immune responses. By binding to specific receptors on cell surfaces, these lectins may enhance the body's ability to identify and destroy cancer cells. The extracts are typically administered subcutaneously, which may improve absorption, although detailed research on bioavailability is limited.
Side effects
Generally considered safe when used appropriately, common local side effects from subcutaneous administration of European Mistletoe Extract include redness, swelling, and pain at the injection site. Uncommon reactions may include mild allergic responses or fever. Severe allergic reactions, while rare, have been documented. There are potential interactions with immunosuppressive medications, and it is contraindicated in individuals with active autoimmune diseases or severe allergies. Caution is recommended for pregnant or breastfeeding women due to insufficient safety data in these populations.
Dosage
Dosing of European Mistletoe Leaf Extract is variable and not firmly established across studies. It is often administered subcutaneously, with dosages tailored to individual tolerance and response. Optimal dosage ranges can differ based on specific treatment protocols; however, high doses should be approached with caution due to an increased risk of adverse effects. There's no well-defined maximum safe dose; thus, medical supervision is essential for any administration.
