Posted 27 July 2023

Researchers in India analyzed individual case reports from the World Health Organization (WHO) database (VigiBase) from between January 2016 and June 2021 describing adverse skin reactions linked to plant-based and animal-based products in natural form (described as traditional medicine).

A total of 5,686 reports (19.9% of all adverse reaction reports) involved 8,588 skin-related reactions. Out of those reports, 3,523 involving 5,761 suspected skin-related reactions had sufficient information to be considered in the final analysis. The analysis revealed:

  • the most common skin reactions were itching (29.6%), rash (20.3%), and hives (18.9%)

Bleeding risks of dietary supplements after surgery and anticoagulant use spotlighted

Posted 03 January 2023

After identifying the 47 most popular dietary-supplement ingredients in the U.S., researchers reviewed the literature on the risks of bleeding they pose to patients postoperatively and while taking anticoagulant medications. [Hatfield J and others. Dietary supplements and bleeding. Baylor University Medical Center Proceedings. 35:802–807, 2022]

They found:

  • Garlic and hawthorn supplementation is strongly associated with surgical bleeding.
  • Cordyceps sinensis, echinacea, and aloe vera were each associated with surgical bleeding in just one case report.
  • Ginkgo biloba, chondroitin-glucosamine, melatonin, turmeric, bilberry, chamomile, fenugreek, milk thistle, and peppermint are associated with bleeding risk for patients taking anticoagulants.
  • Fish oil, ginseng, and saw palmetto are not linked to bleeding.
  • Evidence for overall bleeding risk of St. John’s wort, ginger, ginkgo biloba, or cranberry supplementation is conflicting.

Of more than 3,000 studies published from 2003 through 2017 in JAMA and the Lancet, and from 2011 through 2017 in the New England Journal of Medicine, more than one of 10 amounted to a “medical reversal”: a conclusion opposite of what had been conventional wisdom among doctors.

“You come away with a sense of humility,” said Dr. Vinay Prasad of Oregon Health and Science University, who conceived of the study. Read the rest
