While Western medicine is common throughout the world, it is not the only type of medicine that people practice. Another kind of medical treatment is known as acupuncture. In general, it is considered to be an alternative type of medicine, it was developed in China over one thousand years ago, but exactly when and how it was created remain mysteries. Acupuncture involves the inserting of multiple needles into the body. The needles are placed at certain points in the body depending on the type of problem the patient has. According to the theory behind acupuncture, there are places on the skin that are connected to different parts of the body. By pricking the skin with needles at these points, an acupuncturist can help a patient either relieve pain or cure various problems.             Acupuncture is popular in many parts of Asia. It is also becoming more common and attracting new patients in Europe and North America. But many people believe it is ineffective. The main reason they feel that way is that it is difficult to understand how the entire process works. Research into acupuncture’s capabilities has yielded varying results. Some studies show that it is quite effective at relieving pain. Other ones, however, claim that it is merely like a placebo. In other words, people believe acupuncture treatment will be effective, so it winds up helping them.
