Quality control of homoeopathic medicines: standardization of anti-bacterial activity

Homoeopathic medicines are being increasingly scrutinized by regulatory authorities. There is considerable variation in methods of preparation and no generally accepted standard. The authors have tested 55 different mother tinctures for anti-bacterial activity against Staphylococcus aureus, using a previously described method. Twenty mother tinctures were available from more than one manufacturer. In 40percent there were significant differences in anti-bacterial activity between tinctures from different manufacturers

Quality control of homoeopathic medicines: stability of mother tinctures on storage

The stability of 55 mother tinctures stored under standard conditions over a twelve month period was estimated in terms of anti-bacterial activity against Pseudomonas aeruginosa, Bacillus cereus and Staphylococcus aureus. There was little change in activity over the period
