Does my natural product contain lead?
At TADIN Herb and Tea Co.® We are committed to providing affordable herbal solutions you can trust. We are dedicated to following the strict guidelines established by Good Manufacturing Practices (cGMPs), that require us to test our herbs for botanical identity, purity and strength. Our qualified and trusted herbal sources and staff are required to provide clear documentation to validate safe levels of heavy metals, such as lead and any potential contaminants.
Our standards meet or exceed the low levels set by California’s Prop 65 levels for lead and any heavy metal. We are proud members or the American Herbal Products Association and meet AHPA member requirements. At TADIN Herb and Tea Co.® we have worked with many of our trusted herbal suppliers to support Good Agricultural and Collection Practices (GACPs) to support our growers, harvesters, products and mother earth to promote healthy herbs for healthy people, and planet!
Concern over the total “natural” and “artificial” lead content of plants is justified as high levels of lead is toxic to plants, animals and humans. Unfortunately, the “artificial” lead content of the earth’s biosphere—due to industrialization, automobile use, lead extraction and lead disposal—has increased since the late 19th century significantly, thus affecting the original “natural” low levels of lead in plants and causing concern. As concern has grown, government policies to limit lead in gasoline, water and industrial discharge has helped lower levels of lead in natural products.
Lead is the heaviest of the non-radioactive metals and it naturally occurs in substantial quantities on the earth’s surface. Lead is present in all soils, rivers, lakes, seawater and despite its weight, also in the air. Parts per million or “ppm” is the measurement used to quantify the concentration of lead in organic matter like soil and water. Natural levels of lead in soil range between 50 and 400 ppm and have never been lead free.
Analysis was made of natural vegetation from uncontaminated primitive areas to establish a normal background value of lead. This analysis shows that there is a wide range of lead concentration depending on growing conditions, species of plant, plant part and growing season. The factors that contribute to contamination (toxic levels) of food and forage crops by “artificial” lead are insecticide sprays, automobile exhaust fumes and industrial smoke exposure.
Even though lead has always been present in our biosphere, the issue of anomalously high lead levels in some food, air and drinking water must continue to be monitored closely. The Environmental Protection Agency’s website on lead contamination provides practical advice on limiting lead exposure such as keeping a clean, well-maintained home and eating well-balanced healthy meals.
