Access • Data measuring access levels and affordability • Official recognition of the role of traditional medical practice providers 96 | Traditional medicine • Cooperation between traditional medical practice providers and allopathic practitioners • Attention to the unsustainable use of medicinal plant resources generic stromectol 3mg otc. National policy and regulation Regulatory/legal mechanisms During the colonial period order stromectol 3mg on-line, traditional medical practice was discouraged or prohibited in most African countries discount stromectol 3mg with amex. A legal framework for the practice of traditional medicine is in place in 53% of states and management bodies for the coor- dination of matters pertaining to traditional practice in 57%. In 2006, South Africa established a Directorate of Traditional Medicine within the Health Ministry and in 2007 enacted the Traditional Practitioners Act (No. In 2008 a Draft National Policy on African Traditional Medicine (Government Gazette No. As pointed out by Twumasi and Warren,34 local associations of traditional healers have always existed in Africa, formed along ethnic/linguistic (Figure 5. Amalgamation of these local associations into a single national umbrella body, speaking with one voice and with a uniform code of practice and criteria for registration/ accreditation, has proved difficult in many African states. It must be remembered that African traditional health systems have cultural and spiritual as well as physical components. A cautionary note in this regard has been sounded by MacCormack:35 Traditional medical practice in Africa | 99 Figure 5. Their office in that group and the entire corporate group’s role in the local society, must be allowed for in health planning which seeks to achieve health for all through community participation. Plucking the practitioners, or the chemicals from their herbal reme- dies, out of the context of healing and transferring them to the university, is a gesture of goodwill but it is not truly a collaborative association of plural medical systems. Iwu23 noted that ‘the African medical system does 100 | Traditional medicine not fall into the sphere of what is known as “alternative medicine”, but is rather a complementary but different medical system that uses medicine in a more or less conventional manner for the treatment of diseases. It employs, in a fundamental sense, the same basic methods as Western medi- cine, with additional contributions from the spiritual dimension, which gives the healing depth and meaning within the African cosmology and experience. The South African Draft National Policy (2008) on African Traditional Medicine explicitly states that, while aiming at the institutionalisation of traditional medical practice, it does not envisage integration of traditional medical practice within the allopathic system; the intention is that the two systems will function side by side under the state healthcare umbrella. Equitable distribution of benefits with respect to indigenous knowledge systems While it is widely acknowledged that indigenous knowledge merits protec- tion and that the holders of such knowledge are entitled to benefits derived from its use, there is no consensus at present as to how this is best achieved. The required legis- lation was enacted in South Africa in 2004 (South African Environmental Management: Biodiversity Act No. The regulations implementing those terms that relate to bioprospecting, access and benefit sharing (section 97(1): d–h) state that permits will be required for all bioprospecting activi- ties (which include those based on traditional knowledge). Benefit-sharing agreements will have to be drawn up between all would-be bioprospectors and stakeholders, according to a specified template. Regulation 10(3) lays down principles for identifying stakeholders, including communities or parts of communities. An interesting test case in this regard is that of the San peoples in southern Africa, whose claim to intellectual property rights in the use of Hoodia (Figure 5. In most African states, no public financing Traditional medical practice in Africa | 103 mechanisms or private insurance programmes exist for traditional healthcare services, the costs of which are paid out of pocket by the patient. Efficacy/safety/quality Efficacy – an adequate evidence base for traditional medical practice therapies and products Considerable research effort on the part of the multinational pharmaceutical industry was devoted during the period 1985–2000 to bioprospecting, guided by ethnobotanical ‘leads’. The purpose was new drug discovery for the treat- ment of essentially first-world health problems, e. The generally adopted approach was that of bioassay-guided fractionation in order to isolate one or more ‘actives’ that might lend themselves to laboratory synthesis and/or subsequent structural modification. An example is the isolation of the alkaloid galanthamine from Balkan Galanthus (snowdrop) spp. Since the year 2000, the main thrust of ethnomedical screening of African plants appears to have shifted from the domain of the multinational pharmaceutical industry47 to that of public research institutions or private enterprises within individual African states. The focus of this research has also shifted, with less emphasis on first-world diseases and more on the major causes of mortality/morbidity in Africa, e. An example of a national initiative is the current South African research and development programme for novel drug development from indigenous medicinal plants (see www. Initially destined to run over 3 years (2004–6), the programme is on-going and has published some of its preliminary findings. When we came to the Coperbergh in October, it was being gathered from the surrounding hills by everybody (to serve as a supply for the whole year).

Respect and caring in nursing require full par- ticipation of persons, families, and communities in Enhancing care describes nursing and social assessment, design, and evaluation of services. This method that provided by a local health-care is defined as a “route of knowing” and “a route to provider. The environment, one of and families can be known, and care designed, the oldest concepts in nursing described by offered, and evaluated (Barry, 1998; Parker, Barry, Nightingale (1859/1992), is not only immediate & King, 2000).

Another modern way of delivering herbs is through granulated herbs buy cheap stromectol 3mg on-line, which are highly concentrated powdered extracts purchase 3mg stromectol with amex. These powders are made by first preparing the herbs as a traditional decoction order 3 mg stromectol amex, after which the decoction is dehydrated to leave a powder residue. Practitioners can mix these powders together for each patient into a custom formula. The powder is then placed in hot water to recreate the decoction, which eliminates the need to prepare the herbs at home, but still retains much of the original decoction’s potency. Example of a prescription An example of the ingredients for a dried herb prescription is shown in Figure 6. Chinese patent medicines Pre-made formulae are available as pills, tablets, capsules, powders, alcohol extracts, water extracts, etc. Most of these formulae are very convenient because they do not necessitate patient preparation and are easy to take. These products are usually not as potent as the traditional extemporaneous Traditional Chinese medicine | 157 preparation of decoction described above. They are not ‘patented’ in the western sense of the word because there are no exclusive rights to the formula. All Chinese patent medicines of the same name have the same proportions of ingredients. A medicine known as ‘four gentleman decoction’ (si jun zi tang) is an example of such a product. The formula comprises: • Main herb: Radix panax ginseng (ren shen), to enhance spleen qi • Associate: Rhizoma atractylodis macrocephalae (bai zhu), to strengthen the spleen and dry off the ‘dampness’ • Adjuvant: Sclerotium poriae cocos (fu ling), to assist the main and associate herbs • Guide: Radix glycyrrhizae uralensis (zhi gan cao), to harmonise the other three herbs and regulate spleen qi. Under the Drug Administration Act 2001 post-marketing surveillance of adverse drug reactions is mandatory in China. Whenever an adverse reaction event occurs, the manufacturer, the medical institutions and the seller are obliged to report it. The main legislation requires that medicines placed on the market must have a licence, which requires meeting standards of safety, quality and efficacy. These licensing conditions pose inappropriate demands on most herbal medicines, because plants are chemically complex and variable, active constituents are not always known and the huge costs cannot be recouped through patenting. Under the 1968 Act, herbal remedies are exempt from the licensing requirement if either the herbal remedy is made up on the premises from which it is supplied, after a one-to-one consultation (Section 6. These exemptions only apply to plant remedies, so medicines containing non-plant ingredients require a medicine licence. In recent years these provisions, which provide no specific regulation for herbal medicines, have been considered inadequate to ensure their safety and quality. There are a number of reasons including: adverse effects from some herbal ingredients (natural does not mean safe); misidentification of some Figure 6. Traditional Chinese medicine | 159 herbs and occasional substitution of toxic for safe species; illegal inclusion of prescription-only drugs or heavy metals in some ‘herbal’ medicines; microbial contamination; and discovery of problematic herb–drug interactions. This establishes a registration scheme for industrially produced over-the-counter herbal medicines, under which manufacturers have to demonstrate safety and quality, but not efficacy. Quality is guided by European good manufacturing practice, and safety is protected by requiring evidence of at least 30 years of safe use, of which at least 15 years must be within the European Community. There is a lead-in time to allow manufacturers and suppliers to make the necessary adjustments, but after 2011 any over-the-counter herbal product that is not registered under this scheme will be illegal. This lead time is, however, only for products that were on the market before April 2004. Such medicines will not have to be licensed and, because they are not industrially produced, will not have to be registered under the European Directive. There are, however, concerns about the quality and safety of herbal medicines supplied by this route. The issue is how to strengthen the public’s protection while preserving their access to herbal medicines. First, members of the statutory register can be tied, through a codes of practice, to suppliers that have been audited and demonstrated satisfactory standards of quality assurance. The Register of Chinese Herbal 160 | Traditional medicine Medicine has provided a good model for such an arrangement through its Approved Suppliers scheme. As it will be illegal to practise under the title of herbalist or Chinese medicine practitioner without membership of the register, the public will have stronger assurance about the quality of Section 6.
