The products that they used were purchased in local Chinese shops in Canada, said Dr. H.C. George Wong of the University of British Columbia, Vancouver. The products involved were: * Tong Shap-Yee’s Shuenchih Wan (“pill for easy breathing”), which contained aminophylline 200 mg and ephedrine HC1 1.3 mg. * Xiaoke Wan (“pill for thirst relief”), containing Radix Astragali, R. Rehmanniae, R.
