A number of TM/CAM medication therapies are very potent and sometimes toxic. Such medicines are often processed before use in order to decrease the toxicity. If incorrectly processed or used, these medicines can be very harmful and cause poisoning. In countries where such medicines are available, consumers need to be aware that they should not be used without a prescription and detailed instructions from a registered TM/CAM practitioner or a conventional health care provider knowledgeable in TM/CAM.
Often only certain TM/CAM practitioners have the legal right to prescribe potent and/or toxic medication therapies. Where this is the case, this is also something the consumer needs to be aware of (see section 4.6). A list of all toxic TM/CAM medication therapies can also be helpful for the consumer. In addition, consumers should pay particular attention to the prescriptions and dosage recommendations for these medications. Common symptoms of poisoning and possible pathways for reporting such suspected poisoning need to be described in accompanying information material (see section 3.2.2).
