Acute upper respiratory tract viral infections are the most commondiseases of human beings (Eccles 2005). Adults have two to five common coldseach year and school children have from seven to ten colds per year (Johnston1996).
The common cold is most often caused byrhinoviruses (Heikkinen 2003). It is a short mild illness with early symptomsof headache, sneezing, chills and sore throat, and later symptoms of nasaldischarge, nasal obstruction, cough and malaise (Eccles 2005). Generally, theseverity of symptoms increases rapidly, peaking 2-3 days after infection, witha mean duration of symptoms of 7-10 days but with some symptoms persisting formore than 3 weeks.
Influenza is caused by infectionwith influenza A and B viruses. In the UK, outbreaks of influenza occur in mostwinters, cause much illness and are a major burden on the NHS (Meier 2000). Influenzais an unpleasant but usually self-limiting disease. The illness can affect both the upper and lowerrespiratory tract, and is often accompanied by systemic signs and symptoms,such as: abrupt onset of fever; chills; non-productive cough; myalgias;headache; nasal congestion; sore throat; and fatigue (Cox 1998). It maybe complicated by, for example, otitis media, bacterial sinusitis, secondarybacterial pneumonia, meningitis, encephalitis or exacerbations of underlyingdisease (Department of Health 2010). In the UK, 1.3% of people with influenza-like illness are hospitalisedeach year (Cooper 2003), and influenza and its complications cause around3,000-4,000 deaths in an average year (far more during a major epidemic) (Meier2000). Older people, young children and immunosuppressed people are most atrisk of developing complications.
The aim of management is to reducethe duration and severity of influenza symptoms, and the risk of complications;and to minimise adverse effects of treatment. Management of the common coldinvolves drugs to alleviate symptoms, such as mild analgesics. For influenza,there are also antivirals.

Evidence from randomised controlled trials suggeststhat electroacupuncture (Xiao 2007), acupuncture (Kawakita 2008; Kawakita 2004)and acupressure (Takeuchi 1999) may help relieve the symptoms of the commoncold (see Table below). However, there is very little research so far in thisarea, and substantially more would be required to draw firm conclusions.
Acupuncture may help relievesymptoms of colds and flu by:
Acupuncture is a tried and testedsystem of traditional medicine, which has been used in China and other easterncultures for thousands of years to restore, promote and maintain good health.Its benefits are now widely acknowledged all over the world and in the pastdecade traditional acupuncture has begun to feature more prominently inmainstream healthcare in the UK. In conjunction with needling, the practitionermay use techniques such as moxibustion, cupping, massage orelectro-acupuncture. They may also suggest dietary or lifestyle changes.
Traditional acupuncture takes aholistic approach to health and regards illness as a sign that the body is outof balance. The exact pattern and degree of imbalance is unique to eachindividual. The traditional acupuncturist's skill lies in identifying theprecise nature of the underlying disharmony and selecting the most effectivetreatment. The choice of acupuncture points will be specific to each patient'sneeds. Traditional acupuncture can also be used as a preventive measure tostrengthen the constitution and promote general well-being.
An increasing weight of evidencefrom Western scientific research (see overleaf) is demonstrating theeffectiveness of acupuncture for treating a wide variety of conditions. From abiomedical viewpoint, acupuncture is believed to stimulate the nervous system,influencing the production of the body's communication substances - hormonesand neurotransmitters. The resulting biochemical changes activate the body'sself-regulating homeostatic systems, stimulating its natural healing abilitiesand promoting physical and emotional well-being.
With over 3000 members, the British Acupuncture Council (BAcC) is the UK's largest professional body for traditional acupuncturists. Membership of the BAcC guarantees excellence in training, safe practice and professional conduct.

Xiao L et al. Clinical observation on effects of acupuncture at Dazhui (GV 14) for abating fever of common cold. Chinese acupuncture & moxibustion 2007; 27: 169-72.
A randomised controlled trial that explored the therapeutic effect of acupuncture for abating fever of common cold. Two hundred and sixty-one patients were assigned to electroacupuncture or a control group given antondine injection. The transient effect of abating fever within 24 h was observed. After treatment, the body temperature at all observation time points in the treatment group were lower than those in the control group (p<0.01). The effect-appearing time (1.42 hours) was shorter in the treatment group than in the control group (3.44 hours, p<0.01). The cure rate and the abating fever rate were better (27.8% and 75.9%) with electroacupuncture that with the control ( 10.9% and 55.5%) (p<0.01). The researchers concluded that electroacupuncture had a definite therapeutic effect on high fever due to the common cold, and that the treatment should be taken as early as possible.
Kawakita K et al. Preventive and curative effects of acupuncture on the common cold: a multicentre randomized controlled trial in Japan. Complementary Therapies in Medicine 2004 Dec; 12: 181-8.
A trial that determined the preventive and curative effects of manual acupuncture on the symptoms of the common cold. A total of 326 participants were randomly allocated to acupuncture and no-treatment control groups. Acupuncture treatments were performed four times during the 2-week experimental period with a 2-week follow-up period. A common cold diary was scored daily for 4 weeks, and a common cold questionnaire was scored before each acupuncture treatment and twice at weekly intervals. The diary score in the acupuncture group tended to decrease after treatment, but the difference between groups was not significant Statistically significantly fewer symptoms were reported in the questionnaire by the acupuncture group than control group (p=0.024). No severe adverse event was reported. The researchers concluded that the trial found a significantly positive effect of acupuncture, and that use of acupuncture for symptoms of the common cold should be considered.
Takeuchi H et al. The effects of nasal massage of the "yingxiang" acupuncture point on nasal airway resistance and sensation of nasal airflow in patients with nasal congestion associated with acute upper respiratory tract infection. American Journal of Rhinology 1999; 13: 77-9.
A randomised controlled trial that determined whether nasal massage of a specific acupuncture point in patients with nasal congestion had any effect on nasal airway resistance (NAR) measured by posterior rhinomanometry and sensation of nasal airflow measured on a visual analogue scale (VAS). Twenty patients were randomized into two groups; one group self massaged the acupuncture point for 30 seconds, while the other group acted as control group without nasal massage. NAR and VAS were measured at baseline, and at 2 and 10 minutes after massage. At the end of the study, patients were asked to score any change in their nasal congestion. There was no statistically significant difference between the two groups in percentage change in NAR or VAS from baseline at any time during the study, although the massage group showed trends toward decongestion and relief from congestion. At the end of the study, more patients in the massage group than the control group felt their nasal congestion was improved.

Kavoussi B, Ross BE. The neuroimmune basis of anti-inflammatory acupuncture. Integr Cancer Ther 2007; 6: 251-7.
Review article that suggests the anti-inflammatory actions of traditional and electro-acupuncture are mediated by efferent vagus nerve activation and inflammatory macrophage deactivation.
Zijlstra FJ et al. Anti-inflammatory actions of acupuncture. Mediators Inflamm 2003; 12: 59-69.
An article that suggests a hypothesis for anti-inflammatory action of acupuncture: Insertion of acupuncture needles initially stimulates production of beta-endorphins, CGRP and substance P, leading to further stimulation of cytokines and NO. While high levels of CGRP have been shown to be pro-inflammatory, CGRP in low concentrations exerts potent anti-inflammatory actions. Therefore, a frequently applied 'low-dose' treatment of acupuncture could provoke a sustained release of CGRP with anti-inflammatory activity, without stimulation of pro-inflammatory cells.
Pomeranz B. Scientific basis of acupuncture. In: Stux G, Pomeranz B, eds. Acupuncture Textbook and Atlas. Heidelberg: Springer-Verlag; 1987: 1-18.
Needle activation of A delta and C afferent nerve fibres in muscle sends signals to the spinal cord, where dynorphin and enkephalins are released. Afferent pathways continue to the midbrain, triggering excitatory and inhibitory mediators in spinal cord. Ensuing release of serotonin and norepinephrine onto the spinal cord leads to pain transmission being inhibited both pre- and postsynaptically in the spinothalamic tract. Finally, these signals reach the hypothalamus and pituitary, triggering release of adrenocorticotropic hormones and beta-endorphin.
