§ Dr. FORGANasked the Minister of Health if he will institute an inquiry into the therapeutic and prophylactic values of medicinal and nutritional preparations of vitamin extracts, with a view to their standardisation and prescription, as far as may be deemed advisable, under the National Health Insurance scheme?
§ Mr. GREENWOODMy hon. Friend is probably aware that methods for the quantitative estimation of vitamins are being actively studied under the auspices of the Medical Research Council. I am advised that knowledge in this subject is not yet sufficiently advanced to justify the consideration of the question of adopting and applying official standards of strength for medicinal preparations of these substances.
