Kutter we do indeed use Medical leaches here BUT as I said NOT for treating high blood pressure. Nowadays used for removing pooled blood from operation or trauma sites. Also removing face bruising such as black eyes of brides to be before the wedding so they do not appear in the photographs for ever though this service does not come cheap.
You folks have a differing system for purchasing Acids, on this side of the pond you purchase from Laboratory suppliers in standard concentrated form then dilute to the percentage you require using distilled water. That means one bottle making as many percentage cuts as required, at a far lower cost.
