I should not be answering for Charlie. Let me speculate a moment. I remember there was an irate poster that was only upset; because she did not want to take anything where she did not know the ingredients. Would you? Me neither. But Charlie is not obligated to go beyond that. Just the ingredients. Now, people with compromised immune systems or pregnant will know; and can decide whether it is a risk.
Honestly, I think you would do well to contact him; as I said originally. I have found him easy to talk with. I believe he can help you in several ways. You have his email addr. Please try.
