Chinese arrhythmia in traditional medicine

Last Updated on

May 04, 2018 – All natural is healthy. This is a common belief for many, particularly when shopping for alternative medicines and dietary supplements. For many, however, the contrary might be fatally true.

As a point in case, new research shows, that substances in Traditional Chinese Medicine  (TCM) can cause severe cardiac arrhythmia. Thus,

Dehydroevodiamine (DHE)

extracts of the plant Evodia rutaecarpa are used in Traditional Chinese Medicine for a variety of symptoms, such as headaches, nausea and vomiting as well as menstrual complaints and ulcers in the mouth area.

Researchers led by Professor Matthias Hamburger from the Department of Pharmaceutical Sciences at the University of Basel investigated the effect of Evodia extracts in collaboration with pharmacologists and toxicologists from the University of Vienna. The natural substances dehydroevodiamine (DHE) and hortiamine isolated from the plant in Basel proved to be very potent inhibitors of potassium channels in the heart muscle. If these channels are blocked, the excitation processes in the heart muscle change, which can trigger severe heart rhythm disturbances, so-called Torsade de pointes (TdP), and ventricular fibrillation and lead to sudden cardiac death (SCD).

Effect confirmed in animal models

The development of severe TdP arrhythmias following the administration of DHE was confirmed by researchers at the University of Utrecht in ECG studies on dogs, a model that is also used to test drug safety in the industry. Further investigations showed that the two natural substances cause oscillations in the heart muscle cells even in very low concentrations, which can cause cardiac arrhythmia. For instance, these substances can get into a tea made from Evodia fruits.

For drugs that may potentially trigger cardiac arrhythmias, it is typically required that a cardiac examination using ECG is carried out before medication. This is especially true for heart disease patients for their risk to be assessed. To date, no clinical studies have been conducted to investigate the incidence of cardiac arrhythmias after taking Evodia preparations.

Re-evaluate security

Studies at the University of Basel have also shown that the DHE content of Evodia fruits is considerable. Hamburger currently investigates the extent to which these substances find their way into tea preparations. “If DHE and hortiamine are detected, the safety of Evodia products has to be re-evaluated,” says Hamburger. TCM medicinal plants and products reach the European market relatively uncontrolled, and they can also be purchased on the internet.

The authors of the study, therefore, call for increased vigilance regarding possible toxic effects of Evodia preparations. “The popularization of medicinal plants from other cultures entails risks. These plants can contain highly active substances with side effects, as in the case of Evodia. A closer examination of such risks is therefore indispensable to protect the population,” says Hamburger.

Lurking genetic predisposition for SCD in the general population

In the general population, who will at one time or another relay on traditional medicines for alleviating some disturbances on health, the exist genetic predispositions for intermediate phenotypes of SCD such as coronary artery disease and electrocardiographic variables (QT interval, QRS duration, and RR interval) as well as  rare and common variants that are associated with SCD.  An extended understanding of the genetics of SCD and the associated predispositions of individuals for SCD may help to avoid fatal events when relying on traditional medicines. perhaps not only Chinese Traditional Medicines, but also many medicines from other cultures.

  • Researchers identify new gene mutation in familial thyroid cancers November 20, 2019
    Researchers from Penn State College of Medicine identified a new gene mutation that may cause a type of familial thyroid cancer. Dr. Darrin Bann, an otolaryngology resident at the College of Medicine and lead author of the study, said that this mutation is the first and only mutation associated with familial thyroid cancer to be […]
  • Researchers develop new database of druggable fusion targets November 20, 2019
    When sections from two separate genes merge due to various factors, such as translocation or splicing, the hybrid that is formed is called a gene fusion. In recent years, it has been discovered that these fusion events play a vital role in the development of cancers and other complex diseases. However, there are very few […]
  • Early results of CRISPR gene-editing treatment shows promise in first human trials November 20, 2019
    Officials from Vertex Pharmaceuticals and CRISPR Therapeutics have announced that preliminary results from testing CRISPR gene-editing treatment in human patients with blood disorders show promise thus far. The joint project between the two firms is taking place at one location in Europe and another in the United States. The results have been posted on the […]
  • Whole-genome sequencing analysis to find more exact biomarkers November 20, 2019
    A new study from Uppsala University shows that whole-genome sequencing increases the precision of genetic studies, which in turn can improve our understanding of how to use biomarkers to discover disease. The results are published in the scientific journal Scientific Reports.

  • Non-invasive microscopy detects activation state and distinguishes between cell types November 20, 2019
    Most analytical methods in biology require invasive procedures to analyze samples, which leads to irreversible changes or even their destruction. Here, researchers from Osaka University develop a non-invasive, label-free optical approach along with statistical tools to reveal immune cell type, cell activation state, and single cell heterogeneity.
  • Living in ethnic enclaves may improve pregnancy outcomes for Asian/Pacific islanders November 20, 2019
    Among Asian/Pacific Islander women living in the United States, those who reside in ethnic enclaves--areas with a high concentration of residents of a similar ancestry--are less likely to have pregnancy or birth complications than those living in other areas, suggests a study by researchers at the National Institutes of Health and other institutions.
  • Study: Young children can learn math skills from intelligent virtual characters November 20, 2019
    A new study examined whether young children's verbal engagement with an onscreen interactive media character could boost their math skills. The study concluded that children's parasocial (that is, one-sided) emotional relationships with the intelligent character and their parasocial interactions (in this case, talking about math with the character) led to quicker, more accurate math responses […]
