Under the Medicinal Products (Prescription and Control of Supply) Regulations, 2003 (as amended), the plant mentioned by the Deputy is available for sale or supply only on foot of a prescription from a registered medical practitioner. I am advised by the Irish Medicines Board that interactions between the plant and a large number of commonly used medicines can lead to a potential decrease in the effectiveness of those medicines. It is therefore considered that the medicinal use and safety profile of the plant requires the intervention and supervision of a medical practitioner to ensure correct diagnosis, usage and patient care.
