What can it help with?
Ancient: Egyptians, Indians, Arabs, and Greeks all used leeches therapeutically.
Why does it work?
(Sig, et al 2017). Cooper and Mologne (2017) report that leech saliva contains over 100 bioactive substances:
anaesthetics(to reduce or stop pain)
vasodilators (to improve blood supply)
bacteriostatics (to stop bacteria from reproducing)
anti-inflammatories (to reduce or stop inflammation)
anti-edematous (to reduce oedema)
anti-coagulants (to stop blood clotting)
Medicinal leeches are single use.
