We have chosen to include the "Prop 65" reproductive health warning label on our packaging. The State of California requires a warning for any product sold in California that would result in a consumer ingesting more than 0.5 micrograms of lead in a day. This is an exceedingly low level that is, by law, 1000 times lower than the level of exposure that has been shown to have no observable effect on humans or animals. Therefore, the law sets an extremely stringent warning threshold. In fact, most whole herb and spice supplements (such as teas and adaptogenic herbs) have this Prop 65 warning on their label as well, or have chosen to only include this warning on the packaging sent sold to California citizens. Many herbs contain very low levels of lead, an element that can be found commonly or naturally in soil, plants, and water, that may trigger the requirement to warn. Rather than limiting our customers’ access to whole herb products in California - and reduce their healing effects - we have chosen to issue the warning specified under Proposition 65. All of our herbs that we source test well within the internationally accepted safety standards for dietary supplements (ANSI 173). We source our herbs from an extremely well-trusted and respected company that uses dried whole herbs grown in nature. This company does not intentionally add any lead to any of its products.
