This blooming plant has got me thinking about medicinal product safety and government regulations. Valerian ( Valeriana officinalis ) has been used as sedative and relaxant for thousands of years. In Canada natural health products go through a listing procedure. I searched the government database and found 514 registered products that list Valerian as an ingredient. Why not check out your favorite medicinal herb at http://webprod5.hc-sc.gc.ca/lnhpd-bdpsnh/index-eng.jsp and see the sort of products it is used in ?
