Running Head: MAPPING THE DISSOCIATED BODY 1 Mapping the Dissociated Body Elizabeth Hough Lesley University Running Head: MAPPING THE DISSOCIATED BODY 2 Abstract This capstone thesis explored the use of body mapping and body scans as a tool for assessing and tracking somatic dissociation and embodiment. The researcher utilized a client- centered approach and mindfulness-based interventions and theory to ground the work with the clients. While there were a variety of questionnaire-based tools for assessing dissociation with clients, many of them were lacking in the somatic component of dissociation. The available assessments were also exclusively self-reported and written or verbal, which had the potential to result in biased reporting. Clients may have also struggled to identify their level of somatic dissociation due to an inherent disconnection or dismissal of their somatic experience. This research described two case studies in which body scans and body mapping were utilized as a method to assess and track the client’s level of body dissociation and embodiment.

    Datura- A Devil Weed Or Angel’s Trumpet. Review Article by : Shaheen Bibi Email: [email protected] 1 Datura Inoxia- A Devil weed or Angel’s Trumpet Abstract Datura is a mystery Plant. It belongs to family Solanaceae. There are many important species of genus Datura. Despite of many reports about being toxic, its still debated for its medicinal properties. The genus Datura has a vast history from early time through World War till modern times. Since long time, Datura has been used as a folk medicine in many ancient cultures and even used today. The ethnobotanical information predicts its useful drug value. This plant is well known for its hallucinogenic property. Heiser states that Datura is genus of contrast-from smelly weeds to lovely ornamentals”. 38 Analyzing the chemical profile of Datura , it is reported to be rich in alkaloids. These alkaloids are member of Tropane. Important tropines are Atropine, Scopolamine and Hyoscyamine. The highest in percentage of atropine in D.inoxia is found in its seeds.39 Datura can cause various complications. Some of its effects are systemic. The primary and alarming sign of toxicity with D.inoxia is mydriasis i.e. the change in pupil centration 40,41. Atropine also has the hallucination effect. It blocks the action of acetylcholine at its receptors. Datura inoxia foliage is also harmful for grazing animals or animals that feed on the seeds. Datura inoxia has an anticholinergic property. This property is due to presence of Scopolamine 18. Interestingly, there are beetles and some bees that survive on Datura and they have established certain biochemical mechanisms to defend themselves against the plants intoxicating chemicals.

They are taken as medication, and are occasionally confused with some other similar plants which are commonly used as medications. This manuscript describes four cases of aconite poisoning that were managed in the Manipal Teaching Hospital. The patients presented with classical symptoms of aconite poisoning such as perioral paraesthesia, generalized burning sensation, and cardiac manifestations such as hypotension and ventricular tachycardia. Since Aconite is a dangerous life threatening herb, one should be aware of this poison. We report four patients who presented with aconite poisoning after mistakenly ingesting aconite, thinking it to be related to medicinal plants. Keywords: Aconite poisoning, Cardiotoxicity, Nepal 1.

Do You Know What I Know? Examining the Therapist's Internal Experience when a Patient Dissociates in Session Abstract There is rich theoretical literature that cites the importance of the therapist’s use of self as a way of knowing, especially in cases where a patient has been severely traumatized in early life. There is limited empirical research that explores the in-session experience of therapists working with traumatized patients in order to support these claims. This study employed a qualitative design to explore a therapist’s internal experience when a patient dissociates in session. The aim of this study was to further develop the theoretical construct of dissociative attunement to explain the way that therapist and patient engage in a nonverbal process of synchronicity that has the potential to communicate dissociated images, affect or somatosensory experiences by way of the therapist’s internal experience.

    Hallucinogens And Dissociative Drug Use And Addiction Introduction Hallucinogens are a diverse group of drugs that cause alterations in perception, thought, or mood. This heterogeneous group has compounds with different chemical structures, different mechanisms of action, and different adverse effects. Despite their description, most hallucinogens do not consistently cause hallucinations. The drugs are more likely to cause changes in mood or in thought than actual hallucinations. Hallucinogenic substances that form naturally have been used worldwide for millennia to induce altered states for religious or spiritual purposes. While these practices still exist, the more common use of hallucinogens today involves the recreational use of synthetic hallucinogens. Hallucinogen And Dissociative Drug Toxicity Hallucinogens comprise a collection of compounds that are used to induce hallucinations or alterations of consciousness. Hallucinogens are drugs that cause alteration of visual, auditory, or tactile perceptions; they are also referred to as a class of drugs that cause alteration of thought and emotion. Hallucinogens disrupt a person’s ability to think and communicate effectively. Hallucinations are defined as false sensations that have no basis in reality: The sensory experience is not actually there. The term “hallucinogen” is slightly misleading because hallucinogens do not consistently cause hallucinations. 1 ce4less.com ce4less.com ce4less.com ce4less.com ce4less.com ce4less.com ce4less.com How hallucinogens cause alterations in a person’s sensory experience is not entirely understood. Hallucinogens work, at least in part, by disrupting communication between neurotransmitter systems throughout the body including those that regulate sleep, hunger, sexual behavior and muscle control. Patients under the influence of hallucinogens may show a wide range of unusual and often sudden, volatile behaviors with the potential to rapidly fluctuate from a relaxed, euphoric state to one of extreme agitation and aggression.

Campus, Nainital, Uttarakhand, India. Accepted 7 January, 2014 Alpine and subalpine regions of Kumaun Himalaya were surveyed qualitatively and quantitatively for the population study to determine the status of Aconitum ferox and A. heterophyllum. Low population density across the surveyed populations and restricted distribution to specific pockets indicates poor availability of the species in the study area. Illegal and over exploitation of these species pose threat to their existence. The present study clarifies the population structure of identified aconite species in Kumaun Himalaya. Observations reveal that on the basis of six attributes (that is habitat preference, distribution range, population size, use pattern, extraction trend, native and endemic species) used to assign threat categories, both the Aconitum species are endangered. Key words: Endangered, Himalaya, Aconitum heterophyllum, Aconitum ferox, medicinal plant. INTRODUCTION Since time immemorial, Himalaya is famous for its rich Indian System of Medicine (ISM).
