Un estudio en Boston encuentra cantidades importantes de metales pesados tóxicos en productos «médicos» fabricados a base de hierbas. Para que luego se hable de medicina natural.
Robert B. Saper, now at Boston University’s School of Medicine, and his colleagues purchased imported Ayurvedic herbal medicine products from stores near Boston’s city hall and had them tested for metal contamination. They discovered that a fifth of the 70 samples tested contained lead, mercury or arsenic, or some combination of all three, in significant quantities. If taken as directed, the products would expose a person to more of the metals than is deemed safe by the Environmental Protection Agency.
