Medicinal Herbs Found Contaminated with Pesticides
Botanical supplements have become an increasingly part of the American diet, however many herbal supplements have not been evaluated for pesticide contanimations.
Researchers publishing in the March 2013 issue of Analytical Chemistry, tested for the presences of 310 different pesticides. Here's what they found:
- Hops - Quinoxyfen (100-620 μg/kg)
- Licorice - Tetraconazole (48 μg/kg)
- Mallow - Tetramethrin (15 μg/kg),
- Tea - Methamidophos (50 μg/kg)
- Tribulus - Chlorpyrifos (93 μg/kg)
- Ginsengs - Quintozene contaminants (hexachlorobenzene, tecnazene), hexachlorocyclohexanes and DDT, azoxystrobin, diazinon, and dimethomorph (0.7 to 2800 μg/kg)

Soil Association - "Organic farming depends on encouraging a diverse ecosystem to maintain soil fertility and to keep pests under control naturally. It does this by encouraging nature’s own predators by maintaining hedgerows and creating open, ‘wild’ spaces at the side of fields, and changing the crops planted each season, to keep soil fertile and avoid the need for chemicals."
Pesticides and inorganic fertilizers Bacteria, fungi, protozoa, nematodes and microarthropods need to be balanced in the soil to make different plant species thrive. These balances have been observed in soils all over the world where plants grow without pesticides or inorganic fertilizers.
