Absolutely! It's like asking, is real food (i.e. fruits and vegetables) safe to eat? Herbs are noble foods in powdered or liquid form. They are 100% organic, digestible, and assemble by the human body (unlike harmful, man-made pharmaceutical drugs which toxify the human body). People should actually ask their doctors "are these drugs safe to take?" instead of asking about herbs being safe to take. It is drugs (legal drugs, O-T-C) that kill hundreds of thousands of people per year whereas 0% herbs are killing people per year.
