Leeches have been used for more than 2,500 years to treat many different ailments. The blood-suckers are utilized in India and other countries to treat gout, arthritis, vertigo, sinusitis and even acne.

An enzyme in the leeches’ saliva is believed to increase blood flow to damaged tissue.

According to alternative medicine experts, cupping may look strange – but it’s a real healer.

The ancient Chinese practice can be used on the back, neck and legs to soften muscles and restore healthy blood flow.
