Horse-leeches are raised as pets.

An American therapist feeds huge horse-leeches in the room and lets them suck blood once a month to improve health.

Therapist Ariane Khomjani cultivates 4 horse-leeches (Hirudinaria Manillensis) of Asian origin in the bedroom at Walnut Creeky, California, USA. Khomjani explained that each leech has his own personality, some adventurous, while others are timider. “Some animals take blood more than others. When they are full, they are satisfied to lie down and rest,” Khomjani said.

“When the leeches suck blood, you often don’t feel anything even for large horse-leeches, although the bite is a bit painful at first,” Khomjani explained. After each meal, the horse-leeches can last up to a year. However, experts recommend against blood-sucking leukemia without consulting your doctor. Many people are allergic to leech saliva and are at risk of infection from this parasite.

According to Khomjani, most bites heal on their own without scarring, but due to the antifungal saliva of the leech, it sometimes takes a few days to stop bleeding. Raising leeches for healing originates from about 3,000 years ago. Under Victoria, doctors encouraged leeches to cure all illnesses from headaches to hysteria. The fever of Hirudo medicinalis has caused a rapid decline in the number of species on the Eurasian continent. Today, leech Hirudo medicinalis is a protected species. Some hospitals still use them to treat blood clots for patients.

Leeches in the world.

There are more than 600 species of leeches all over the world and most of them suck blood. Few species such as worms (Pharyngobdellida) are predators that devour invertebrates, some species of leeches that eat mulch or organic debris. The leech has 8 pairs of single eyes to detect the shadow of potential prey. Their brains form from 32 nodes located along the vertebrae of the body. Leeches are hermaphrodites, each of them has male and female genitalia but they still need partners to fertilize.

If a hungry leech senses body temperature or CO2 in human breath, it can crawl closer to the target by mouth and suction. When a suitable host is found, they secrete anesthetic and anticoagulant and bite the victim with jagged jaws.
