“…Investigations are now focused on the search of novel and better tolerated molecules from natural resources to control the severity and the progression of mental disorders (Chatterjee et al, 2011b(Chatterjee et al, , 2013Ishola et al, 2012;Zhang, 2004). Natural products have characteristically high chemical diversity, biochemical specificity, and several other medicinal properties that make them favorable lead structures for the treatment for various disorders, including psychosis.…”

(2015) Antipsychotic activity of standardized Bacopa extract against ketamine-induced experimental psychosis in mice: Evidence for the involvement of dopaminergic, serotonergic, and cholinergic systems, Pharmaceutical Biology, 53:12, 1850-1860, DOI: 10.3109/13880209.2014 (40, 80, and 120 mg/kg, p.o.) were given to the mice 1 h prior to ketamine administration and tested for positive symptoms and cognitive deficits. A chronic ketamine treatment regimen was used to study the effect of BM on negative symptoms such as immobility enhancement. Each mouse was used once for the behavioral studies.Results: BM reduced ketamine-induced hyperactivity with an EC 50 value of 76.60 mg/kg. The 80 mg/kg dose was used for all other behavior analysis. Pretreatment with BM at 80 mg/kg showed two-fold increases in transfer latency time (TLT) in passive avoidance task. Chronic BM pretreatment (80 mg/kg p.o. daily Â 10 d) ameliorated the ketamine-induced enhanced immobility effect by 21% in the forced swim test. BM treatment reversed ketamine-induced increase in monoamine oxidase activity in both cortex and striatum and normalized the acetylcholinesterase activity and the glutamate levels in the hippocampus. Discussion and conclusion: Overall our findings suggest that BM possesses antipsychotic properties which might be due to its modulatory action on dopamine, serotonin, and glutamate neurotransmission.

“…Therefore, the use of medicinal plants for neurological and psychiatric diseases has progressed significantly owing to their fewer side effects and better reliability [20]. The aim of the present study was to evaluate the implantation, fertility index and teratogenic properties of somina, a unani anxiolytic in rats.…”

Objective: Somina (herbal medicine) is used in Pakistan as Unani anxiolytics. It is composed of five medicinal plants. The current work was designed to evaluate the general reproductive and teratogenic effects of somina in two consecutive generations of rats according to the OECD guideline.Methods: Fertility study (a two-phase study) was done in Sprague-Dawley rats. 1st part: three groups' female rats (10 rats each group) received different doses orally. First group: The control group (saline), a single oral human dose of somina (2 nd group: 285 mg/kg/day) and the high dose of somina (3 rd group: 1g/kg/day) during the whole period of gestation till the delivery of pups named as F1 Breed. For the second part of study ten females were selected from each F1 breed (control, somina 285 mg/kg/d, somina 1g/kg/day) and administered the same treatment from day first of mating than the entire period of gestation until F1 breed delivered pups (F2 breed). For F1 and F2 breed the fertility index and litter size were determined. Some of the female rats (F1 and F2) were anesthetized and autopsied. The blood sample was subjected to biochemical analysis and serum liver function test: bilirubin, gamma-glutamyl transferase (γGT), alanine aminotransferase (ALT: SGPT), aspartate aminotransferase (AST: SGOT) and alkaline phosphatase (ALP) were measured spectrophotometrically. The uterine growth index, fertility index, and litter size were also measured to evaluate the teratogenic effects of somina treated rats. Results:The data showed that any significant different (P>0.05) was not found during the maternal examination (uterine growth index, fertility index) and reproductive parameters (litter size, the quantity of fetus, aborted or absorbed fetus) in somina treated rats as compare to control rats (P>0.05). Control and treated Pups did not show any significant (P>0.05) malformation and any congenital defects. Non-significant (P>0.05) changes were observed in liver function test. It was found normal in all groups. Macroscopic autopsy examination also did not reveal any significant (P>0.05) pathological findings in the liver, kidneys, and uterus. Conclusion:The oral administration of somina during the gestational period of pregnant female rats was not teratogenic/fetotoxic. Any adverse or deleterious effects were not observed at the dose of 285 mg/kg (human dose) or 1g/kg (3times greater than the human dose) during pregnancy, and it is safe in rats.

RESUMO: "Tratamento da dependência de drogas com plantas medicinais brasileiras". O tema "Plantas medicinais no tratamento de dependência" em um país deve ser precedido pela resposta a quatro questões: 1. O país em questão possui biodiversidade sufi ciente para permitir a descoberta de remédios naturais úteis? 2. Seus habitantes possuem tradição e cultura de procurar e utilizar recursos da natureza para aliviar e curar doenças, incluindo dependência de drogas? 3. O problema de dependência de drogas está presente no país em questão? 4. Seus habitantes reconhecem e diagnosticam a dependência de drogas como um sério problema? O álcool é, de longe, o mais sério problema de saúde quando o assunto abuso de drogas é considerado, atingindo toda a sociedade brasileira, incluindo os índios. Ao contrário, outras drogas podem ser consideradas como problemas menores e não são o foco principal deste artigo. As pessoas vivendo nas terras brasileiras mais isoladas não têm acesso ao sistema público de saúde. Conseqüentemente, estas pessoas procuram tratamento com curandeiros e raizeiros; ou, no caso dos indígenas, com os shamans. Estes doutores populares não conhecem a medicina e terapêutica acadêmicas e recorrem a plantas locais para tratar as diferentes patologias que acometem seus pacientes. Entretanto, o abuso e dependência de álcool não são vistos por eles como problemas de saúde segundo as regras e critérios da medicina acadêmica. Um levantamento foi feito em diversos livros brasileiros, teses sobre fi toterapia e alguns bancos de dados. Os resultados de tal pesquisa foram frustrantes. Não foram encontrados artigos de autores brasileiros sobre o uso de plantas para o tratamento de dependência de drogas nos bancos de dados consultados e apenas três notas muito curtas em um livro clássico escrito por Shultes e Raffauf (1990). Dos livros brasileiros sobre o uso popular de plantas medicinais, foram obtidas dez menções: a maioria delas sobre o tratamento de problemas relatados ao álcool e duas delas a respeito do tratamento da dependência de "Ayahuasca".Unitermos: Plantas medicinais, dependência de drogas, alcoolismo, Brasil, tratamento, biodiversidade. ABSTRACT:The topic "Herbal Medicines in the Treatment of Addictions" in a country must be preceded by answers to four questions: 1. Does the country in question possess a biodiversity rich enough to allow the discovery of useful medicines? 2. Do local people have tradition and culture to look for and use resources from Nature to alleviate and cure diseases, including drug dependence? 3. Is drug dependence (or addiction) present in the country in question? 4. Do people of that country recognize and diagnose such problem as a serious one? Alcohol is, by far, the most serious health problem when drug abuse is considered, reaching all of Brazilian society, including the Indians. On the contrary, other drugs may be considered as minor problems and they are not the main focus of this manuscript. The people living in Brazilian hinterland don't have access to public health systems. Cons...
