In traditional medicine, Cannabis sativa L. has been used for variety of reasons. Old literatures delineate that Cannabis had been used as anesthetic and analgesic, or to reduce symptoms such as cough, paralysis and so on. Although Cannabis has a long history of medical use, it is illegal in many countries including South Korea. Controversy over decriminalization of Cannabis to allow cannabis for therapeutic use has been around for many years. In order to understand current knowledge on the therapeutic use of medical Cannabis, comprehension of cannabinoids and other constituents of Cannabis is important. Here we reviewed the pharmacological effect of Cannabis and current mandatory regulation over Cannabis in many countries to suggest necessity of research on medical Cannabis.

Objectives : This study aims to examine the efficacy and application of Cannabis according to its parts. Methods : Contents on efficacy, treatment, and application of Cannabis in Material Medica and other texts of East Asian Medicine were collected and interpreted to deduce each characteristic. Results : Cannabis was found to be applicable to various wind symptoms and wind stroke, various pain and injuries, skin diseases, blockage or leaking of urine or feces, disease related to genitalia and anus, chronic ague, women's disease related to menstruation, birth, pregnancy, and to have the effects of heightening perceptive and sensory organs, detoxification and anesthesia, stimulating hair growth, and eradicating parasites. It drives out wind-heat pathogenic qi, circulates qi and blood, which allowed it to be applied not only to blockages but to symptoms of leakage. In other words, Cannabis was used when both excess and deficiency diseases were present, the former caused by acute blockage and the latter accompanied by stagnation. Conclusions : Based on the findings of this study, future researches on the efficacy and application of Cannabis could be done more systematically. In line with recent trend of wide application of medical Cannabis, we hope for it to be more actively used in the field of East Asian Medicine based on objective evidence.

This study aimed to explore research on bibliometric features of cannabis by applying scientometric analysis method, and to approach experimental research evaluation based on it. A total of 30,352 articles on cannabis published since 2001 from SCOPUS were analyzed using KnowledgeMatrix Plus and VOSviewer software. Results showed differences in research activities in countries where cannabis is legalized (Canada, the United States, the Netherlands) and Asian countries where its use is illegal. Related to medical cannabis, there has been a noticeable increase in the number of studies on pain, epilepsy, seizures and brain diseases such as multiple sclerosis. In the field of basic research, the number of pharmacological studies of cannabis on the cannabinoid type 1 receptor signaling pathway and inflammation and obesity has increased significantly. Subsequent experimental studies have compared the anti-inflammatory effects of four parts of Korean cannabis such as root, stem, leaf, and bark. Consistent with the predicted results of the scientometric analysis, all parts of C. sativa showed inhibitory effects on COX-2, NO/iNOS and TNF-α expression in LPS-stimulated RAW264.7 cells. These attempts provide an experimental research approach based on scientometric assessment.

Cannabis is a historical plant which has been used as a medicine in East Asia. These days, there are active debates about using cannabis in clinical field. Collecting and comparing cannabis research articles which had been published in the Opening of Japan to spot the interactions between the traditional medicine of Japan, Rangaku which was established in Edo Period and the European medicine which is transferred after Perry Expedition is academically meaningful. This study searched publications, which were listed on Open-Access databases by Dec. 11^th, 2019. We collected research articles which had been published from January 3^rd, 1867 to July 30^th, 1912 also known as Meiji era and uploaded on OpenAccess databases. Our searching databases were J-stage, CiNii (Scholarly and Academic Information Navigator), Tokyo Metropolitan Library, The National Diet Library, IRDB (Institutional Repositories DataBase) and KAKEN (Grant-in-Aid for Scientific Research Database). Searching keywords were cannabis, hemp and all their Japanese synonyms and available combinations. We selected final 15 studies which met every selection criteria in the 346,393 collected studies. Cannabis was prescribed in Meiji era of Japan to alleviate pain and cure the digestive, respiratory, urinary, and nervous system diseases such as indigestion, asthma, tuberculosis, gonorrhea and its complications, insomnia, and nervous prostration. Cannabis was medically used in Meiji era of Japan and the reporting and sharing of its clinical effect was published on the medical journals like present days. There were already Cannabis regulations in that era, but its medicinal use was more liberated than nowadays. It may be a chance to reconsider the current legal system, which strictly controls the use of Cannabis.

Objectives: This study was to discuss the research trend of dementia treatment using cannabis for the purpose of providing the basis of cannabis use for medical purposes in the future. Methods: This study searched publications, which were registered to databases or published by Aug 22, 2019, and targeted the full-text or abstracts of these publications. We selected the final nine studies met all selection criteria. Results: These results implied that the CBD components of cannabis might be useful to treat and prevent AD because CBD components could suppress the main causal factors of AD. Moreover, it was suggested that using CBD and THC together could be more useful than using CBD or THC alone. Conclusion: We hope that there will be a solid foundation to use cannabis for medical use by continuously evaluating the possibility of using cannabis for clinical purposes as a dementia treatment substance and cannabis can be used as a positive tool.

Objectives: This study explored the prevalence and predictors of alcohol and cannabis co-use among 9263 Filipino adolescents, using data from the 2019 Global School-based Student Health Survey (GSHS). Methods: We conducted a cross-sectional secondary analysis of the GSHS, targeting adolescents aged 13-17 years and excluding cases with incomplete data on alcohol and cannabis use. Our analysis employed the bivariate chi-square test of independence and multivariable logistic regression using Stata version 18 to identify significant predictors of co-use, with a p-value threshold set at 0.05. Results: The weighted prevalence of co-users was 4.2% (95% confidence interval [CI], 3.4 to 5.3). Significant predictors included male sex (adjusted odds ratio [aOR], 4.50; 95% CI, 3.31 to 6.10; p<0.001) and being in a lower academic year, specifically grade 7 (aOR, 4.08; 95% CI, 2.39 to 6.99; p<0.001) and grade 8 (aOR, 2.20; 95% CI, 1.30 to 3.72; p=0.003). Poor sleep quality was also a significant predictor (aOR, 1.77; 95% CI, 1.29 to 2.44; p<0.001), as was a history of attempted suicide (aOR, 5.31; 95% CI, 4.00 to 7.06; p<0.001). Physical inactivity was associated with lower odds of co-use (aOR, 0.45; 95% CI, 0.33 to 0.62; p<0.001). Additionally, non-attendance of physical education classes (aOR, 1.48; 95% CI, 1.06 to 2.05; p=0.021), infrequent unapproved parental checks (aOR, 1.37; 95% CI, 1.04 to 1.80; p=0.024), and lower parental awareness of free-time activities (aOR, 0.63; 95% CI, 0.45 to 0.87; p=0.005) were associated with higher odds of co-use. Factors not significantly linked to co-use included age group, being in grade 9, always feeling lonely, having no close friends, being bullied outside school, and whether a parent or guardian understood the adolescent's worries. Conclusions: The findings highlight the critical need for comprehensive interventions in the Philippines, addressing not only physical inactivity and parental monitoring but also focusing on sex, academic grade, participation in physical education classes, sleep quality, and suicide attempt history, to effectively reduce alcohol and cannabis co-use among adolescents.

Cannabis sativa (CS) has been in the spotlight not only for its medical uses but also as a raw material for cosmetics. As fermented cosmetics are known to have various health benefits, they have been extensively researched. Here, we investigated the characteristics of CS stems fermented using various gut microbes. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide assay and melanin content analysis revealed that melan-a cells containing CS stems fermented with Weissella paramesenteroides (CSWP) showed considerably reduced melanin content. Additionally, CSWP downregulated the expression of several melanogenesis factors, tyrosinase-related protein-1, and tyrosinase-related protein-2. This study suggests that the anti-melanogenic effect of CSWP could provide a new basis for the development of skin-lightening agents.

Objectives : The purpose of this study is to investigate splenic constipation syndrome(脾約證) in Shanghanlun by comparing 179 & 247 provisions. Methods : Including Shanghanlun, several texts which contain Cheng Wu-ji, Wan Mi-zhai, Qian Huang, Zhu Gong, Fang You-zhi, Yu Jia-yan, Zhang Lu, Cheng Ying-mao, Zhang Xi-ju, Chen Xiu-yuan, Wu Qian, Xu Ling-tai, You Zai-jing, Zhu Dan-xi's opinion about the splenic constipation syndrome were chosen and comparative consideration was carried out. Results & Conclusions : The following conclusions could be drawn. 247 provisions in Shanghanlun is different from 179 provisions because the beginning of the each splenic constipation syndrome is different. The difference between 179 & 247 provisions are proved by comparing Mild Purgative Decoction which is used Taiyangyangming splenic constipation syndrome and Fructus Cannabis Pill which is used Dorsal pedal pulse splenic constipation syndrome. Cheng Wu-ji's opinion that 179 & 247 provisions is different is meaningful because he is first investigated the different beginning of the splenic constipation syndrome. Several annotator's opinion which oppose Cheng Wu-ji is majority and they set a high value on Jangbu(臟腑) factor. Several annotator's opinion which agree Cheng Wu-ji is minority and they set a high value on splenic constipation syndrome also begins from Taiyangbing. The concept of overlapping of Taiyangyangming is different from the concept of Taiyangyangming. Consequently 179 & 247 provisions has to be distinguished.
