Acupuncture and Acupressure
The basic difference between acupressure and acupuncture is that the second one uses thin needles in addressing health issues, while the first one doesn't break your skin. However, the two methods of classical holistic medicine have much in common, since they are both based on touching meridians that carry energy, or chi, throughout the body.
In Traditional Chinese Medicine ailments are caused by blockages of chi somewhere along fourteen meridians all over the body, so both acupressure and acupuncture encourage energy to flow freely once again; they are used to treat allergies, arthritis, depression, nausea, migraine headaches, menstrual cramps, and anxiety, according to the philosophy of Traditional Chinese Medicine.
Acupuncture, as the word suggests, punctures the skin with very thin, long needles. They do not resemble the needles you see at a western doctor's office, for they don't inject any material. Acupuncture needles are flexible lengths of disposable, hypoallergenic, sterile metal that a trained acupuncturist delicately inserts beneath the skin. When properly done, this shouldn't hurt at all. The needles reach certain areas, called pressure points or energy gates to break up the blockages.
So Acupressure or Acupuncture, the philosophy is same. It encourages the energy flow to the body and let the body cure itself. It is like supporting the body in its divine process of self healing.
The practitioner may use needle or his/her finger to pressure or touch, they should stick with the ancient philosophy.
