  • Biochemical Benefits, Diagnosis, and Clinical Risks Evaluation of Kratom
    REVIEW published: 24 April 2017 doi: 10.3389/fpsyt.2017.00062 Biochemical Benefits, Diagnosis, and Clinical Risks Evaluation of Kratom Dimy Fluyau1* and Neelambika Revadigar2 1 Brain Health, Emory University, Atlanta, GA, USA, 2 Columbia University, New York, NY, USA Background: Kratom (Mitragyna speciosa) is a tropical tree with a long history of tradi- tional use in parts of Africa and Southeast Asia. Kratom is also known as Thom, Thang, and Biak. Its leaves and the teas brewed from them have long been used by people in that region to manage pain and opioid withdrawal and to stave off fatigue. Kratom is actually consumed throughout the world for its stimulant effects and as an opioid substi- tute (in form of tea, chewed, smoked, or ingested in capsules). Some case reports have associated kratom exposure with psychosis, seizures, intrahepatic cholestasis, other medical conditions, and deaths. The clinical manifestations of kratom effects are not well defined and the clinical studies are limited. Data research suggest that both stimulant and sedative dose-dependent effects do exist, in addition to antinociceptive, antide- pressant activity, anxiolytic-like effects, and anorectic effects, but a growing concern for the drug’s effects and safety of use has resulted in national and international attention primarily due to an increase in hospital visits and deaths in several countries that are Edited by: believed to have been caused by extracts of the plant. There is a dearth of double blind Angelo G. I. Maremmani, controlled studies.

ABSTRACT Introduction: Mitragyna speciosa (Korth.) or kratom is a native medicinal plant of Southeast Asia. Commonly used by hard labours in harsh working environment, the ingestion of brewed kratom decoction is reported to produce dose-dependent stimulant and opioid-like effects. Kratom is also regularly consumed as a pain killer and as tradi- tional cure for common maladies such as fever and cough. However, it remains unknown whether regular consump- tion of kratom decoction is associated with brain abnormalities in regular users in traditional settings.

The results of our study showed that around 0.088 % (w/w) pure mitragynine was obtained by this newly developed method with a purity of 99.0 % (w/w) based on GC-MS analysis. Moreover, the recovery of the pure mitragynine from the chloroform extract was also more than 95.0 %. Advantages of this new method were simpler, faster and more economical. In conclusion this simple and cost effective method helps to isolate mitragynine with higher purity in comparison with the published methods.

(Rubiaceae) a tree found in Southeast Asia (Thailand, Indonesia, Malaysia, Myanmar, Philippines, and Papua New Guinea. Traditionally, the Mitragyna speciosa was used to alleviate pain, hypertension, cough, diarrhea, and as a substitute for morphine in treating addicts. Association of Southeast Asian Nations refers to kratom as a drug. Kratom contains more than 40 types of alkaloids, including Mitragynine speciosa, as many as (66.2%) and their derivatives, speciogynine (6.6%), speciociliatine (0.8%), paynantheine (8.6%), 7-hydroxymitragynine (2%). The article was created to provide information related to the pharmacological effects of kratom, kratom compound analysis, and the potential of compounds from kratom to become new drugs. The method used in this research is to review and analyze kratom articles from research papers, bibliographic reviews, and case reports included, research conducted in Indonesia and in English. The main purpose of this review is not only to understand the chemical content, benefits of kratom, and analytical methodologies for analysis, but also the use of kratom secondary metabolites as therapeutic drugs and the side effects caused by kratom, to help health professionals assess the content of compounds from kratom worthy of being new drugs.
