What is "Warning Prop 65" on Nature's Secret Super Cleanse?

Hi Everyone,

I have recently started a Juice Cleanse mixed with psyillium and Bentonite shakes. Nature's Secret's "Super Cleanse" was recommended as a nessesary herbal supplement to help break down toxins in the colon.

However, I was curious about the Warning Prop 65 label on it so I called them. They told me that the product might have trace amounts of lead because the herbs come from soil which may or may not have trace amounts of lead.

Do you think this is sketchy or okay? I mean, whats the point of doing a cleanse if I'm actually putting lead into my body?
They seem like a good company but I don't know.

Any thoughts??

Thanks
