Sammygol,
I did read your posts, and mine was not meant as a criticism in any way. Nor is this one.
I simply strongly believe in added precautions and warnings.
But now that you mention it, just as you posted, while the substances that you mentioned have been tested, not all substances sold in “natural food” stores have. Also, keep in mind that just as with drugs, a small percentage of people can have very bad allergic or other reactions to some of these substances, and not all companies post adequate warnings on their labels.
