HC Deb 09 December 1968 vol 775 c28W
91. Mr. Lipton

asked the Secretary of State for Social Services what researches have been carried out into the long-term toxic hazards of procaine hydrochloride, the active principle of KH3 capsules.

Mr. Ennals

None, so far as I am aware. Procaine hydrochloride has been in use for over 60 years, but the need to investigate possible long-term toxic hazards has not arisen.

92. Mr. Lipton

asked the Secretary of State for Social Services whether he will ask the Medical Research Council to investigate the claims of the manufacturers of KH3 capsules that these capsules, sold without prescription, have rejuvenating properties.

Mr. Ennals

No. The Medical Research Council do not regard it as part of their normal function to assess the efficacy of individual remedies.
