Welcome to The International Hypnosis Research Institute Web site. Our intention is to support and promote the further worldwide integration of comprehensive evidence-based research and clinical hypnotherapy with mainstream mental health, medicine, and coaching. We do so by disseminating, supporting, and conducting research, providing professional level education, advocating increased level of practitioner competency, and supporting the viability and success of clinical practitioners. Although currently over 80% of our membership is comprised of mental health practitioners, we fully recognize the role, support, involvement, and needs of those in the medical and coaching fields.

Investigation on bioavailability of some essential and toxic elements in medicinal herbs.



Trace and major elements were determined in medicinal herbs (Cynara scolymus, Matricaria chamomilla, Artemisia absinthium L., Achillea millefolium, and Inula britannica) as well as in rhizosphere soil samples. Based on the results obtained after microwave-acid-assisted digestion (nitric acid + hydrogen peroxide) and single-step extraction (ammonium acetate), the real and potential acidity and redox potential of the soils, uptake, mobility, and bioavailability of potassium, calcium, magnesium, iron, manganese, copper, zinc, nickel, chromium, lead, and cadmium are discussed. By calculating the bioconcentration factors and their deviation from the recommended values, elevated concentrations, were explained in terms of contamination and pollution. The concentrations measured in both plants and soil samples were below maximum allowable concentration ranges considered for the European Union.

Chronic arsenic toxicity from Ayurvedic medicines.



BACKGROUND: Ayurvedic medicines are known to contain arsenic and concentrations up to toxic levels have been reported in certain formulations. However, clinical disease due to arsenic containing ayurvedic medicines has rarely been reported. We seek to highlight the existence of toxic levels of arsenic in certain ayurvedic preparations that can produce serious systemic manifestations. METHODS: An 11-year-old girl developed manifestations of arsenical keratosis (punctuate palmoplantar keratoderma and leucomelanoderma) and non-cirrhotic portal hypertension, 6 months and 18 months respectively after intake of ayurvedic medications, prescribed for epilepsy. The eight ayurvedic preparations consumed by the patient and her serum levels were analyzed for arsenic content. RESULTS: Arsenic content of ayurvedic medicines ranged from 5 mg/L to 248 mg/L. The serum arsenic level was 202.20 microg/L (normal < 60 microg/L). Skin manifestations improved after the discontinuation of ayurvedic medications. CONCLUSIONS: Ayurvedic medications should be consumed under strict guidance and supervision of qualified practitioners to prevent such catastrophies.
