WARNING : In the United States, Ricarimpex leeches may only be used as an adjunct to the healing of graft tissue when problems of venous congestion may delay healing, or to overcome problems of venous congestion by creating prolonged localized bleeding. Leeches have not been cleared by the FDA for any of the applications in general medicine described on this website or in any other source of information on medicinal leeches, scientific or otherwise.

Over the last few years, RICARIMPEX has been developing and optimising laboratory breeding methods to enable production to take place entirely within the laboratory setting. Leeches are fed exclusively with poultry blood from a certified company.
