Leech of a free range is not a certified leech.
This type of leech is particularly suitable for therapy for animals or breeding purposes into a natural pond. Leeches of free range grow up in similar circumstances as to grow up in nature and we do not test them regularly for the presence of bacteria and viruses.
Also, we feed the leeches with sterile blood, but they are not recommended for the therapy of humans even if the transmission of harmful bacteria are unlikely, but possible.
If you want to use leech therapy for varicose veins, or for a patient in weight and height above the average, we recommend to use large medical leeches.
If you want to use leech therapy for the child or the visible body parts– concerns mainly women we recommend to use small – cosmetic leeches.
