6 Traditional medicine contribute to health
Artemisinin is a new anti-malarial drug. It was discovered from Artemisia annua L. which is traditionally used Chinese medicine for treatment of malaria and other health problems. WHO recommends to use Artemisinin based combined therapy (ACT) for the treatment of falciparum malaria since 2002 Currently, Tamiflu is the only drug for avian influenza. It is based on shikimic acid which is abstracted from plant Illicium lanceolalum, which is also one of traditionally used Chinese medicines

7 Difficulties Specific to TM/CAM Research
Characteristics of Western Medicine The main philosophy of Western Medicine is that if the human body is struck by diseases, the causative agent must be identified and dealt with in order to return patients to a state of good health.

8 Difficulties Specific to TM/CAM Research
A common feature of most systems of Traditional Medicine is that they take a 'holistic' approach towards the sick individual and treat disturbances on the physical, emotional, mental and living environment levels simultaneously.

9 Procedure for developing a new chemical drug
Duration: at least 13 years Cost: at least US$ 100 million

10 Evaluation of Efficacy of Herbal Medicines
The combination of 4 plants creates powerful synergy for maximum anti-tumour effect Removing any one of the 4 plants weakens the effectiveness of the formula Reported by Prof Yeeng -chi Cheng, Yale Medical School 2001

11 WHO Traditional Medicine Strategy 2002-2005
1 Policy: integrate TM/CAM with national health care systems 2 Safety, efficacy and quality: provide evaluation, guidance and support for effective regulation 3 Access: ensure availability and affordability of TM/CAM, including essential herbal medicines 4 Rational use: promote therapeutically-sound use of TM/CAM by providers and consumers

12 WHO Global Survey and Database of National Policy and Regulation of TM/CAM
WHO Global Survey and Database of National Policy and Regulation of TM/CAM and Herbal Medicines including information from 141 countries, 2004 Summary report of the global survey on national policy on traditional medicine and regulation of herbal medicines 2005

13 WHO Global Survey and database of traditional medicine
Objectives To collect updated and comprehensive information on TM/CAM policies and regulations of herbal medicines to make analysis on the current situation and major challenges To clarify what are specific needs on capacity building regarding TM/CAM and regulations of herbal medicines and what directed support WHO should provide to the Member States accordingly. r To update the document “Regulatory Situation of Herbal Medicines- a world wide review”. To monitor the impact of the WHO Strategy for Traditional Medicine in relation to present national policy and regulation on TM/CAM/herbal medicines.

14 Challenges of definition of herbal medicines
Finished herbal products Finished herbal products consist of herbal preparations made from one or more herbs. If more than one herb is used, the term mixture herbal product can also be used. Finished herbal products and mixture herbal products may contain excipients in addition to the active ingredients. However, finished products or mixture products to which chemically defined active substances have been added, including synthetic compounds and/or isolated constituents from herbal materials, are not considered to be herbal. Recommendation from workshop of herbal medicines, 11th ICDRA, 2002 Member States should strengthen the post-marketing surveillance system of herbal medicines. Particular attention should be given to the possible adulteration of herbal medicines by chemicals or other ingredients which have not been labelled.

15 Number of Member States with Recently Established Herbal Medicines Law or Regulation
65% of respondents have established herbal medicines law or regulation 42 (49%) declared regulations were in the process of being developed. Number of Countries before 1986: 14 Number of Countries Total:

16 Types of herbal medicines regulation
Respondents were able to answer with more than one option, if applicable, so the total number exceeds number of respondents

17 Regulatory status of herbal medicines
Respondents were able to answer with more than one option, if applicable, so the total number exceeds number of respondents

18 Challenges of regulatory status of herbal medicines
e.,g Garlic If Garlic intends to be used as food spice, it is food, but if it is used to stop diarrhoea, it is herbal medicines Garlic gel is categorised a herbal medicine product in Germany Garlic gel is categorised a food supplement in UK and USA Garlic gel is categorised a health food in Japan

19 Challenges of regulatory status of herbal medicines
It is difficult to distinguish between herbal medicines and health food or diet-supplement Definition depend on countries own used experience Definition highly depend on labeling and intended use (claims) Highly depend national regulation of food and medicines Clinical or bibliographic data on efficacy could refer to regulate products into diet-supplement or medicine categories

20 Types of claims allowed for herbal medicines
Respondents were able to answer with more than one option, if applicable, so the total number exceeds number of respondents

21 What is "evidence" in the field of medicine?
Randomized selection, Double-blinded, Placebo-controlled trials. A Randomized Controlled Trials 8% (RCT) Well-conducted Clinical % Studies Expert Committee Reviews % or the clinical experience of respected authors. B C “Using Clinical Guidelines to Improve Patient Care within the NHS "1996

22 Level of evidence requirement (Australia)
Level of claim Type of claim Evidence required of support claim HIGH Treats/cures/manages any disease/disorder. Prevention of any disease or disorder. Treatment of vitamin or mineral deficiency diseases. High level. Registration only –evaluated by the CMEC, MEC (Medicines Evaluation Committee) or the ADEC (Australian Drug Evaluation Committee). MEDIUM Health enhancement2. Reduction of risk of a disease/disorder. Reduction in frequency of a discrete event. Aids/assists in the management of a named symptom/disease/disorder.Relief of symptoms of a named disease or disorder3. Medium level. Sponsor must hold the evidence for Listable goods. GENERAL Health maintenance, including nutritional support.Vitamin or mineral supplementation4. Relief of symptoms (not related to a disease or disorder)3. General level. Sponsor must hold the evidence for Listable goods.

23 Level of evidence required for the regulation of TM/CAM
Two types of evidence which can be used to support claims (EU) scientific evidence evidence based on traditional use of products, which have been on the market for at least 30 years without any risks reported. (15 years within European countries and 15 outside European countries)

24 Number of Registered Herbal Medicines
Number of Countries Total: 66

25 Number of Member States with Regulatory Requirements for Good Manufacturing Practice

26 Major problems of international herbal markets
Quality problems Quality inconsistence Use wrong species Labelling problem lack precautions Including heavy metals Including chemical substance or illegal substance without announcement Other problems Lack registration information of products in in the original countries Lack producer information in the original countries Lack communication between national drug authorities of imported and exported countries

50 WHO Working group meeting on international regulatory cooperation on herbal medicines
WHO Working group meeting on regulatory cooperation on herbal medicines in Ottawa, Canada from 28 to 30 November 2005 hosted by the Health Products and Food Branch of Health Canada. 29 regulatory authorities from 16 countries participated, regulatory authorities representing each of the 6 regional/sub-regional/inter-regional regulatory cooperation groups including Forum on Harmonization of Herbal Medicines (FHH), the Pan American National Drug Regulatory Authorities Harmonization (PANDRH), the European Herbal Medicines Committee, the ASEAN Product Working Group on Traditional Medicines and Health Supplements (TMHSPWG) and the Latin American Parliament (PARLATINO)

51 International regulatory Cooperation on Herbal Medicines (IRCH)
Objectives globally promote and facilitate the safe use of herbal medicines, including through regional initiatives, through sharing information and fostering dialogue; facilitate and strengthen cooperation between national drug regulatory authorities by sharing experience and information related to the regulation, safety and quality of herbal medicines; further discuss existing requirements and standards to promote the regulation, safety and quality of herbal medicines; further share research and knowledge of traditional medicines to reduce duplication; recommend future activities to WHO related to the safe use of herbal medicines; recommend important issues to ICDRA for further discussion related to the safe use herbal medicines.

52 International regulatory Cooperation on Herbal Medicines (IRCH)
Initial scope of activities of IRCH IRCH is in the initial stages. There are two main activities: Information sharing on technical matters related to regulatory information of herbal medicines via electronic communication as the main tool, on a daily basis, through an Information Focal Point nominated by each Member Country of IRCH. Convening annual meetings of IRCH. Second working group meeting will take place in October 2006, Beijing, China

53 Conclusion Status and regulation of herbal medicines vary between country to country The most difficulties for national authorities are the lack of research data, the lack of appropriate control mechanisms, the lack of education and training of providers and the lack of expertise. Information exchange and sharing national experience is crucial aspect WHO will provide support to the international and regional regulatory cooperation for herbal medicines
