Tin, copper, gold and silver are also possibilities, though they are considered less likely, or to have been used in fewer cases. 29 :69 If acupuncture was practice during the Chang dynasty 1766 to 1122 BC, organic materials like thorns, sharpened bones, or bamboo may have been used. 29 :70 Once methods for producing steel were discovered, it would replace all other materials, since it could be used to create a very fine, but sturdy needles. 29 :74 Gwei-djen and Needham noted that acupuncture to cause bleeding, while others mixed the ideas of blood-letting and spiritual Ph'i energy. Acupuncture.became.he.ost popular alternative medicine in the US. 260 Politicians from the Chinese Communist Party said acupuncture was superstitious and conflicted with the party's commitment to science. 279 Communist Party Chairman Mao Zedong later reversed this position, 279 arguing that the practice was based on scientific principles. 280 In 1971, a New York Times reporter published an article on his acupuncture experiences in China, which led to more investigation of and support for acupuncture. 27 The US President Richard Nixon visited China in 1972 . 281 During one part of the visit, the delegation was shown a patient undergoing major surgery while fully awake, ostensibly receiving acupuncture rather than anaesthesia . 281 Later it was found that the patients selected for the surgery had both a high pain tolerance and received heavy indoctrination before the 94 A 2012 review found that acupuncture seems to be cost-effective for some pain conditions. 242 Risk of forgoing conventional medical care As with other alternative medicines, unethical or naive practitioners may induce patients to exhaust financial resources by pursuing ineffective treatment. 5 243 Profession ethical codes set by accrediting organizations such as the National Certification Commission for Acupuncture and Oriental Medicine require practitioners to make “timely referrals to other health care professionals as may be appropriate.” 244 Stephen Barrett states that there is a “risk that an acupuncturist whose approach to diagnosis is not based on scientific concepts will fail to diagnose a dangerous condition”. 245 Main articles: Qi, Traditional Chinese medicine, Meridian Chinese medicine, and Acupuncture point Old Chinese medical chart of acupuncture meridians Acupuncture is a substantial part of traditional Chinese medicine ACM. 4 Early acupuncture beliefs relied on concepts that are common in ACM, such as a life force energy called qi. 246 Qi was believed to flow from the body's primary organs zang-fu organs to the “superficial” body tissues of the skin, muscles, tendons, bones, and joints, citation needed through channels called meridians. 247 Acupuncture points where needles are inserted are mainly but not always found at locations along the meridians. 248 Acupuncture points not found along a meridian are called extraordinary points and those with no designated site are called “A-shi” points. 248 In ACM, disease is generally perceived as a disharmony or imbalance in energies such as yin, yang, qi, xuĕ, zàng-fǔ, meridians, and of the interaction between the body and the environment. 249 Therapy is based on which “pattern of disharmony” can be identified. 250 251 For example, some diseases are believed to be caused by meridians being invaded with an excess of wind, cold, and damp. 252 In order to determine which pattern is at hand, practitioners examine things like the colon and shape of the tongue, the relative strength of pulse-points, the smell of the breath, the quality of breathing, or the sound of the voice. 253 254 ACM and its concept of disease does not strongly differentiate between the cause and effect of symptoms. 255 Scientific research has not supported the existence of qi, meridians, or yin and yang. n 1 24 25 A Nature editorial described ACM as “fraught with pseudo-science”, with the majority of its treatments having no logical mechanism of action . 256 Quackwatch states that “ACM theory and practice are not based upon the body of knowledge related to health, disease, and health care that has been widely accepted by the scientific community.
