I received my order of oxymatrine white tiger today and it had a sticker on it warning that it contains lead. It came from Pine Street Clinic. I’m concerned about taking it now. Has anyone else seen this on their bottles?
I'm kinda of the opinion that anything grown in soil can have lead in it.
This website says, "...Plants do not take up lead on purpose, because lead is not a plant nutrient. Plants may contain measurable amounts of lead, but this isn’t because plants are actively taking up lead from soil, but because we’re able to measure very low concentrations of lead in environmental samples."
If you want peace of mind about it you could ask the manufacturer if they has a 3rd party assay they can send you. It would show you the level of lead that was found.
That website talked more about levels and absorption if you are interested.
