Western science methodologies have been employed to analyse the effectiveness of herbs and treatment on various individuals generic venlor 75 mg mastercard. Tang has asked whether the current western model of research – trying out unknown treatments in animals – is suitable for studying treatments that have long been used in humans 75 mg venlor sale. Some traditional therapies are undoubtedly effective but this does not mean that all are. Tang Traditional Chinese medicine | 133 suggests that there is a much greater need to determine whether Chinese medicinal herbs do work rather than how they might work. Overall, 95% of general hospitals in China have traditional medicine departments, which treat about 20% of outpatients daily. Acupuncture is used widely in western Asia, Australia, Canada and parts of Europe (Figure 6. Ancient works were generally written on bamboo strips and silk, and have not survived. Subsequently, it went into gradual decline until 1822, when it was finally banned by Emperor Dao Guang, who disapproved of its practices. In the early part of the twentieth century acupuncture became part of the ongoing debate as to whether Chinese culture should be overtaken by western influences or maintain its own traditions. With the arrival of western medicine, acupuncture was increasingly relegated to rural and remote back- waters. Acupuncture developed once again as people were quickly trained and pressed into service. News of the success of acupuncture was brought to the west in 1683 by Dr Willen Ten Rhijn, a physician working for the Dutch East Indies Company in Japan. Acupuncture was widely practised in France in the late eighteenth century with Dr Berlioz, a Parisian doctor, becoming the first western prac- titioner of acupuncture in the early nineteenth century. John Churchill, the first British acupuncturist, used the technique in the treatment of rheuma- tism in 1821. Acupuncture was even mentioned in the first edition of The Lancet in 1823 as being chiefly used in ‘diseases of the head and lower belly’. In Scotland, a random survey found that an impressive 94% of respondents in a random survey knew something about acupuncture and 25% said that they would consider using it, although in practice only about 6% had actually done so. Principles of acupuncture In addition to the classic principles of Chinese medicine outlined above, there is one key aspect of practice still to consider. This is the theory of acupuncture points that are stimulated usually by the superficial insertion of 136 | Traditional medicine needles into the skin. Other methods of stimulation include the application of pressure and the passing of a weak electrical current (see below). A further 1000 extra points and special use points may also be identi- fied on the hands, ears and scalp. It is not known how these points were discov- ered – probably it was by observation over hundreds if not thousands of years – nor is it known exactly how many points were first identified. Acupoints cannot be identified by their appearance and no consistent features of their anatomy have been found that distinguish them from other tissues. Practice of acupuncture There is archaeological evidence that shows that the earliest acupuncture needles date back to the Stone Age, when instruments called bian were thought to have been used in China. Needles were subsequently made of many different metals: gold, silver, copper, etc. Modern acupuncturists use solid sterile disposable needles of narrow bore, about 3 cm long (although longer needles may be used at different sites). As many as 15–20 needles may be inserted superficially at the appro- priate point(s). The practitioner then gently introduces the needles a little more deeply into the muscle, rotating them between finger and thumb. Qi and blood flow throughout the meridians and this is where manipulation of the needle is critical in properly moving this flow. The arrival of qi called deqi is signified by a dull ache or tingling sensation and slight inflammation. Some practitioners may use electrical stimulation, connecting the needles to a small piece of equipment powered by batteries. Needles are left in place for up to 20 min: the patient is invited to lie back and relax. Occasionally a needle may be left in place for several days, normally situated in the ear; these so-called indwelling needles should not be used in patients with heart valve disease or who are immunocompromised.

These diseases affect the digestive system and cause the intestinal tissue to become inflamed buy venlor 75mg mastercard, develop sores purchase 75mg venlor mastercard, and bleed generic venlor 75 mg mastercard. These diseases can be painful and debilitating and may lead to life-threatening complications, especially if untreated. Crohn’s disease and ulcerative colitis are very similar in that they both inflame the lining of your digestive tract and can cause severe bouts of watery or bloody C diarrhea and abdominal pain. Where they differ is that Crohn’s disease can occur anywhere in your digestive tract, often spreading deep into the layers of affected tis- sues whereas ulcerative colitis usually affects only the innermost lining of your large intestine (colon) and rectum. Symptoms may come and go and those affected may also experience long periods of remission. Stress can aggravate symptoms, and was once considered to be the underlying cause, but that is no longer the case. Many practitioners, especially those with knowledge of nutrition and preventative medicine, feel that diet may be responsible for triggering these diseases. Both diseases are rare in developing countries and among cultures that eat whole, unprocessed foods. As well, it wasn’t until the mid-1900s that these diseases became a problem in North America. Consumption of fast foods and processed and refined foods and ingestion of chemical food additives is common. It is also possible that the inflammation may stem from the immune system’s response to infection with a virus or bacterium. Since the diseases are more common among those with a family history, genetic mutations may also be to blame. While there is no known medical cure for Crohn’s disease or colitis, there are a variety of lifestyle approaches, supplements, and medications that can reduce the symptoms and even bring about long-term remission. Some people with these diseases experience inflammation in other areas of the body (joints, skin, and eyes). Depending on your situation and the severity of the symptoms and intestinal damage, your doctor may prescribe drug therapy to control the inflammation. Commonly used drugs include sulfasalazine, mesalamine (Asacol), and corticosteroids, such as prednisone. As well, these drugs have serious side effects, so it is important to discuss the benefits and risks with your doctor. Iron supplements are used for anemia, which occurs from chronic intestinal bleeding. For severe cases, surgery to remove the diseased portions of the bowel may be necessary, but this is always the last resort. One study of people with colitis found that 100 mL of aloe vera juice twice daily resulted in a complete remission or an improvement in symptoms in 47 percent of cases, compared with 14 percent of those given a placebo. Herbal teas made from chamomile, slippery elm, and marshmallow can be very soothing to an inflamed gastrointestinal tract. The best sources of these fatty acids are salmon, herring, mackerel, albacore tuna, and sardines. During flare-ups when the intestines are inflamed, raw vegetables and fruits can be irritating, so it is best to cook (steam) these foods. There was a significant clinical improvement (reduction in symptoms) in 78 percent of people who were given wheat grass compared to 30 percent who were given placebo. Wheat grass contains vitamins A, C, E, B-vitamins, calcium, magnesium, potassium, iron, natural en- zymes, and chlorophyll. Carrageenan, a compound used to stabilize milk proteins, has been shown to induce ulcerative colitis in animals. One study found that those who eat fast foods at least two times per week more than triple their risk of developing Crohn’s disease. Try an elimination diet to determine if food allergies are worsening your symptoms. One study also found that fish oil supplements reduced the risk of relapse and flare-up. Taking a quality multivitamin every day can help restore nutrient levels and improve overall health. Those with severe damage to the intestine may not be able to absorb B12 so injections can be taken. Replacing the flora with probiotic supplements C can help improve digestion and nutrient absorption and relieve constipation and diarrhea. Dosage: Look for a product that provides at least one billion cells per capsule and take twice daily. Some research has shown that it can reduce symptoms of both Crohn’s disease and colitis, similarly to prescription drugs.
