This just begins to scratch the surface of some of the risks associated with herbs. The insights into these risks grows daily. Unfortunately, herbal products are not regulated by the Food and Drug Administration.
Herbal products do have benefit for use with residents of long-term care facilities.
They can provide natural means to address some health conditions and often carry less risks than many of the prescription drugs commonly used with this population. But, they must be used knowledgeably and cautiously. When suggesting to a physician that an herb be tried instead of initiating a prescription drug, or when administering an herb that has been ordered, do some research and know the precautions and interactions associated with the herbs. Your pharmacist may be able to provide you with some guidance. If your facility is using herbs frequently and your facility hasn't already done so, ask your pharmacist to develop an herbal formulary for in-house use.
