It.bread.o.ietnam in the 8th and 9th centuries. 30 As Vietnam began trading with Japan and China around the 9th century, it was influenced by their 18460551 . The.Judy also includes warnings against practising acupuncture on infants, as well as on children who are over-fatigued, very weak, or have overeaten. 240 When used on children, acupuncture is considered safe when administered by well-trained, licensed practitioners using sterile needles; however, a 2011 review found there was limited research to draw definite conclusions about the overall safety of paediatric acupuncture. 3 The same review found 279 adverse events, 25 of them serious. 3 The adverse events were mostly mild in nature e.g. bruising or bleeding. 3 The prevalence of mild adverse events ranged from 10.1% to 13.5%, an estimated 168 incidences among 1,422 patients. 3 On rare occasions adverse events were serious e.g. cardiac rupture or hemoptysis ; much might have been a result of substandard practice. 3 The incidence of serious adverse events was 5 per one million, which included children and adults. 3 When used during pregnancy, the majority of adverse events caused by acupuncture were mild and transient, with few serious adverse events. 241 The most frequent mild adverse event was needling or unspecified pain, followed by bleeding. 241 Although two deaths one stillbirth and one neonatal death were reported, there was a lack of acupuncture-associated maternal mortality. 241 Limiting the evidence as certain, probable or possible in the causality evaluation, the estimated incidence of adverse events following acupuncture in pregnant women was 131 per 10,000. 241 Although acupuncture is not contraindicated in pregnant women, some specific acupuncture points are particularly sensitive to needle insertion; these spots, as well as the abdominal region, should be avoided during pregnancy. 2 Four adverse events associated with moxibustion were bruising, burns and cellulitis, spinal epidural abscess, and large superficial basal cell carcinoma. 16 Ten adverse events were associated with cupping. 16 The minor ones were keloid scarring, burns, and bullae ; 16 the serious ones were acquired haemophilia A, stroke following cupping on the back and neck, factitious panniculitis, reversible cardiac hypertrophy, and iron deficiency anaemia . 16 A 2013 meta-analysis found that acupuncture for chronic low back pain was cost-effective as a complement to standard care, but not as a substitute for standard care except in cases where co morbid depression presented. 19 The same meta-analysis found there was no difference between sham and non-sham acupuncture. 19 A 2011 systematic review found insufficient evidence for the cost-effectiveness of acupuncture in the treatment of chronic low back pain. 20 A 2010 systematic review found that the cost-effectiveness of acupuncture could not be concluded. that time. 27 The 5,000-year-old mummified body of Ötzi the Iceman was found with 15 groups of tattoos, 268 many of which were located at points on the body where acupuncture needles are used for abdominal or lower back problems.
Tin,.opper, 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 Texts dated to be from 156–186 BC document early beliefs in channels of life force energy called meridians that would later be an element in early acupuncture beliefs. 267 Ramey and quell said the “practice and theoretical underpinnings” of modern acupuncture were introduced in the Yellow Emperor's Classic Huangdi Beijing around 100 BC. 28 267 It introduced the concept of using acupuncture to manipulate the flow of life energy qi in a network of meridian channels in the body. 267 272 The network concept was made up of acu-tracts, such as a line down the arms, where it said acupoints were located. Traditionally, acupuncture was used to treat acute conditions as electrical pulses were found to make a frog's leg twitch after death. 269 The West eventually created a belief system based on travel trigger points that were believed to inhibit pain. If.e-qi can not be generated, then inaccurate location of the acupoint, improper depth of needle insertion, inadequate manual manipulation, 29 :71 However, it is more likely that stones were used for other medical purposes, such as puncturing a growth to drain its pus . 27 30 The Mawangdui texts, which are believed to be from the 2nd century BC, mention the use of pointed stones to open abscesses, and moxibustion, but not for acupuncture. 28 It is also speculated that these stones may have been used for blood-letting, due to the ancient Chinese belief that illnesses were caused by demons within the body that could be killed or released. 269 It is likely blood-letting was an antecedent to acupuncture. 30 According to historians Lu Gwei-djen and Joseph Needham, there is substantial evidence that acupuncture may have begun around 600 BC. 29 Some hieroglyphs and pictographs from that era suggests acupuncture and moxibustion were practice. 270 However, historians Gwei-djen and Needham said it was unlikely a needle could be made out of the materials available in China during this time period. 29 :71-72 It is possible Bronze was used for early acupuncture needles.
