Integrative medicine in allergy and immunology

Integrative medicine is a relatively new discipline which attempts to combine allopathic medicine with alternative or complementary medicine, to reap the benefits of both forms of medicine in optimizing the care of patients. Integrative medicine concentrates on treating the patient as a whole, both in body and mind. While the scientific method and "evidence-based" clinical research drives the management and treatment of diseases in conventional Western medicine, alternative or complementary medicine is based on unproven yet potentially beneficial techniques that have been developed throughout history, dating back to the ancient cultures in the Middle East, Africa, and China. In spite of the lack of evidence of most alternative medicine techniques, these methodologies have been practiced for centuries with great acceptance in many countries. It is in the Western world, where "modern" medicine is dictated by the scientific method, that the most controversy in the use of these alternative modes of therapy exists. Since the science behind alternative medicine is incomplete or non-existent, it is difficult for those trained in Western medicine to accept or adopt this approach. But perhaps it is the failure of Western medicine to adequately guarantee our well being and good health that have led to the ongoing debate between the medical profession and the general public as to the benefits of these alternative treatments. In one sense, integrative medicine may be a futile attempt to coin a new term in the hope of legitimizing alternative medicine. On the other hand, there is a wealth of historical experience in the use of the techniques. Studies to evaluate the scientific basis behind ancient medical techniques are ongoing, and it is to be expected that the results will neither be uniformly positive nor negative. Of particular interest is the effect of traditional medicine, herbal formulations, and manipulative techniques on the immune system, and its application in the treatment of autoimmune and allergic diseases. Studies are being designed or conducted to investigate immune effects of herbal formulations or their components. Herbal plants or medicines may lead to skewing of the Th1/Th2 balance in either direction, thus may offer potential application in the treatment of allergic or autoimmune diseases.

Ethnopharmacological survey of medicinal plants used by traditional healers in Bangladesh for gastrointestinal disorders

ETHNOPHARMACOLOGICAL RELEVANCE

Gastrointestinal diseases are common worldwide, including Bangladesh where majority of the rural people depend on water from unprotected sources. The people from Bangladesh use medicinal plants as their first line of health care to cure and prevent different types of gastrointestinal disorders.

AIM OF THE STUDY

To compile plants used for the treatment of different gastrointestinal disorders in Bangladesh.

MATERIALS AND METHODS

The field survey was carried out in a period of 18 months. Fieldwork was undertaken in total of eleven districts of Bangladesh. Open-ended and semi structured questionnaire were used to interview a total of 1280 people including traditional healers, Ayurvedic/Unani drug manufacturers and local people.

RESULTS

A total of 250 plant species of 93 families were listed. Leaves were the most cited plant part used against gastrointestinal disorders. Most of the reported species were tree in nature and decoction is the mode of preparation of major portions of the plant species. Most of the plant species were very common and were cultivated or planted in homestead or roadsides. The doses of the plants for different treatments varied widely.

CONCLUSION

In view of the fact that the plants were selected based on their medicinal usage for treating different kinds of gastrointestinal diseases including diarrhoea, the activities reported here need more works for validation and could be rationalised by the presence of active compounds found in those plants. The documentation represents the preliminary information in need of future phytochemical investigation and is important for the conservation of these plants.

Ethnobotanical survey of Purulia district, West Bengal, India for medicinal plants used against gastrointestinal disorders

ETHNOPHARMACOLOGICAL RELEVANCE

An ethnobotanical survey was conducted in the remote hills, forests and rural areas of Purulia, one of the tribal rich districts of the West Bengal state of eastern India. Purulia is a part of the biogeographic zone Deccan Peninsula Chhotonagpur. The authors have reported the use of medicinal plants by nine tribes of the district against various gastrointestinal disorders.

MATERIALS AND METHODS

Semi structured questionnaire was used during the interview with the informants having traditional botanical knowledge. Bhumijs, Birhor, Gond, Ho, Kharia, Mal Pahariya, Mundas, Oraon and Santhali represent the various aboriginal groups present in the district. The use of medicinal plants were documented using an interview data sheet mentioning the names, age, profession and gender of the informants and scientific and vernacular names, families, part(s) used, disease(s) treated, method of preparation, mode of administration of the botanicals and the preparations.

RESULTS

A total number of 56 plants belonging to 29 families have been reported to be used against different types of gastrointestinal disorders viz. indigestion, stomach pain, vomiting tendency, constipation, piles, diarrhea, dysentery, cholera, loss of appetite, liver complaints, intestinal worms etc. Fabaceae and Apocynaceae were found to be the dominant families of medicinal plants used to treat such ailments.

CONCLUSION

Age, gender, literacy and profession of the aboriginals were found to be the significant factors when the traditional knowledge of medicinal botanicals was concerned. Due to urbanization and loss of biodiversity, the authors have noted a significant decrease in the ethnic knowledge as well as the botanicals. Preservation of folklore should be given utmost importance in this region to prevent the rapid loss of ethnobotanical wealth.
