Mistletoe herb has been described as a remedy used for bleeding, high blood pressure, and various other ailments.
- Commission E did not recommend mistletoe preparations for the uses described because it concluded that there was not enough evidence of their effects.
What the authors write
Cold extracts of mistletoe herb were indicated for excessive menstrual bleeding, uterine bleeding, damage to blood vessels, and stress-related exhaustion.
Cold extracts of mistletoe herb were indicated for excessive menstrual bleeding, uterine bleeding, damage to blood vessels, and stress-related exhaustion.

Mistletoe macerates and injections were described as lowering blood pressure, supporting the heart and immune system, calming, and relieving spasms.
Traditionally, mistletoe extracts were used for bleeding, spasms of the digestive tract, tumors, headaches, parasites, and epilepsy.
Since the early 20th century, mistletoe had been recommended for atherosclerosis and high blood pressure, as well as angina.
Cold macerates were described as being used for high blood pressure, bleeding, epilepsy, and low immunity; an ointment made from the berries was used on external cancerous tumors.
Older accounts attributed various uses to mistletoe depending on the tree on which it grew, including uses in childbirth and for mental illness, fears, paralysis, and epilepsy.
Older accounts described mistletoe as being used for epilepsy, fever, digestive problems, neuralgia, bleeding, and high blood pressure.

A review with a meta-analysis found improved quality of life in cancer patients using mistletoe extracts.
Aim of the study: Mistletoe extracts are used as an adjunct therapy for cancer patients, but there is disagreement about whether this therapy has a positive impact on quality of life (QoL).
Results: We included 26 publications with 30 data sets. The studies were heterogeneous. The pooled standardized mean difference (random effects model) for global QoL after treatment with mistletoe extracts vs. control was d = 0.61 (95% CI 0.41-0.81, p < 0.00001). The effect was stronger for younger patients, with longer treatment, in studies with lower risk of bias, and in randomized and blinded studies. Sensitivity analyses support the validity of the finding. 50% of the QoL subdomains (e.g. pain, nausea) show a significant improvement after mistletoe treatment. Most studies have a high risk of bias or at least raise some concern. Mistletoe extracts produce a significant, medium-sized effect on QoL in cancer. Risk of bias in the analyzed studies is likely due to the specific type of treatment, which is difficult to blind; yet this risk is unlikely to affect the outcome.

A meta-analysis found a moderate reduction in cancer-related fatigue after using mistletoe extracts.
Aim of the study: Cancer-related fatigue remains one of the most prevalent and distressing symptoms experienced by cancer patients. Effective treatments for cancer-related fatigue are needed. The objective of this meta-analysis is to determine the impact of mistletoe extracts as a pharmacological treatment for the management of cancer-related fatigue.
Results: We performed one meta-analysis with 12 RCTs, including 1494 participants, and one meta-analysis with seven retrospective NRSIs, including 2668 participants. Heterogeneity between the studies was high in both meta-analyses. Most studies had a high risk of bias. A random-effects model showed for RCTs a standardized mean difference of -0.48 (95% confidence interval -0.82 to -0.14; p = 0.006) and for NRSIs an odds ratio of 0.36 (95% confidence interval 0.20 to 0.66; p = 0.0008). Treatment with mistletoe extracts shows a moderate effect on cancer-related fatigue of similar size to physical activity. These results need to be confirmed by more placebo-controlled trials. Future trials should investigate different treatment durations and their effect on cancer-related fatigue in post-treatment cancer survivors.

A meta-analysis indicated that unfermented mistletoe extract may be associated with longer survival in cancer patients.
Aim of the study: Mistletoe extracts (ME) are used in integrative cancer care to improve quality of life and to prolong survival. ME are available from different producers and differ in pharmaceutical processing, such as fermentation. In contrast to fermented ME, the impact of unfermented extracts on the survival of cancer patients has not yet been assessed in a meta-analysis.
Results: Eleven RCTs and eight NRSIs met the inclusion criteria. The studies were heterogeneous and their ROB2 and ROBINS-I displayed a moderate and high risk of bias, respectively. For RCTs, the pooled effect estimate of non-fermented ME on survival was HR = 0.81 (95% CI 0.69-0.95, P = .01). Subgroup analyses as well as the NRSIs estimation support the robustness of the finding. When active comparators are added to the analysis, the effect estimates become non-significant. The results may indicate a positive impact of non-fermented ME on the overall survival of cancer patients. High quality RCTs are necessary to substantiate our results.

In rodent studies, mistletoe extracts showed sedative, anxiolytic, antidepressant, and pain-relieving effects.
Aim of the study: The aim of this review is to summarize existing evidence confirming the influence of mistletoe on the central nervous system and to investigate the compounds that may be responsible for this activity.
Results: The main chemical constituents of Viscum L. species are viscotoxins, lectins, flavonoids, phenolic acids, terpenoids, sterols, phenylpropanoids, and alkaloids. Various extracts of Viscum album L. showed central nervous system activity, including antiepileptic, sedative, antipsychotic, anxiolytic, antidepressant and antinociceptive effects in mice and rats. Additionally, the extracts increased the level of brain-derived neurotrophic factor, prevented apoptotic neuronal death induced by amyloid β and weakly inhibited cholinesterase activity. Numerous historical references describe the use of mistletoe for the treatment of central nervous system disorders. In recent years, studies have started to confirm the antiepileptic, antipsychotic, sedative and antinociceptive effects of mistletoe. Additionally, mistletoe can be used as a complementary treatment for Alzheimer's disease.

Mistletoe is used as a supportive treatment for cancer patients, and its effect on quality of life has been assessed positively.
Aim of the study: Mistletoe (Viscum album L.) continues to be the medical herb prescribed most frequently for cancer patients in German-speaking countries.
Results: In Germany, coverage is limited to palliative care. In adjuvant cases, treating physicians can request coverage by the health insurance if patients suffer from side effects due to the antitumoral treatment. The spectrum of Viscum album extract includes mistletoe lectin I, II, and III, viscotoxins, flavonoids, amino acids, polysaccharides, and membrane lipids. Preclinical studies have demonstrated cytotoxic, apoptosis-inducing, and immunomodulatory effects. Many clinical studies indicate a supportive efficacy of mistletoe extracts in tumor patients, even though methodological quality is discussed controversially in many cases.
