In the context of diabetes, the use of cinnamon continues to be among the most popular supplements taken by patients for glucose control. To strategically evaluate the available literature comparing various cinnamon species and statistically significant glucose effects after ranking studies based on two tools to assess bias and overall study quality, to clarify cinnamon\'s role in glucose control. The authors performed a systematic search based upon PRISMA guidelines. The search was conducted utilizing PubMed, AMED, CINAHL, EMBASE, Cochrane, and Medline databases, with the final search performed in September 2022 with restrictions to human subjects and English language. Electronic searches were conducted utilizing the keywords \"diabetes mellitus\" combined with Cinnamomum zeylanicum/Cinnamomum cassia/Cinnamomum verum combined with blood glucose (BG). A second search utilized \"cinnamomum zeylanicum/cinnamomum cassia/cinnamomum verum\" combined with \"blood glucose,\" and a final search utilized \"diabetes mellitus\" combined with \"cinnamon.\" Data extraction and ranking of included studies utilizing the risk of bias 2 tool and modified Heyland Methodological Quality Scoring tool were performed independently by two review authors. These authors compared their results and reconciled any differences in scoring to generate a final ranking of studies. A third author was available for any discrepancies that could not be resolved but was not needed. Forty-five studies were included in the review and were scored for bias and quality. Overall 62% demonstrated statistical significance for positive effects in at least one parameter around BG control. Applying the ranking systems reduced the percentage closer to 50%. Safety was extremely well documented across studies with few adverse effects. Results are limited by heterogeneity of glucose parameters, leading to studies being ranked individually and not synthesized. Cinnamon supplementation likely has a modest positive effect on BG. Based upon the strong safety profile, utilization of this spice as an adjunct to pharmacologic therapy is reasonable.

Traditional medicine is critical in disease treatment and management. Herbs are gaining popularity for disease management and treatment. Therefore, they can be utilised as complementary and alternative treatment (CAT) ingredients. Atopic dermatitis (AD) is one of the common non-communicable diseases. It is characterised by chronic inflammatory skin disease with intense pruritus and eczematous lesions. AD is associated with oxidative stress, microbial infection, and upregulation of inflammatory cytokines. Both children and adults could be affected by this skin disorder. The prevalence of AD is increasing along with the country\'s level of development. This review revisited the literature on four medicinal herbs widely used as complementary medicine to manage AD. These therapeutic herbs are commonly eaten as food and used as spices in Asian cuisine. The four food herbs reviewed are Cassia alata, Coriandrum sativum, Curcuma longa Linn, and Azadirachta indica. Their traditional uses and phytochemical content will be covered. Four relevant pharmacological and biological activities of the plants crucial in AD management have been reviewed and discussed, including anti-inflammatory, anti-microbial, antioxidant, and wound recovery.

Cassia obtusifolia L., of the Leguminosae family, is used as a diuretic, laxative, tonic, purgative, and natural remedy for treating headache, dizziness, constipation, tophobia, and lacrimation and for improving eyesight. It is commonly used in tea in Korea. Various anthraquinone derivatives make up its main chemical constituents: emodin, chrysophanol, physcion, obtusifolin, obtusin, au rantio-obtusin, chryso-obtusin, alaternin, questin, aloe-emodin, gluco-aurantio-obtusin, gluco-obtusifolin, naphthopyrone glycosides, toralactone-9-β-gentiobioside, toralactone gentiobioside, and cassiaside. C. obtusifolia L. possesses a wide range of pharmacological properties (e.g., antidiabetic, antimicrobial, anti-inflammatory, hepatoprotective, and neuroprotective properties) and may be used to treat Alzheimer\'s disease, Parkinson\'s disease, and cancer. In addition, C. obtusifolia L. contributes to histamine release and antiplatelet aggregation. This review summarizes the botanical, phytochemical, and pharmacological features of C. obtusifolia and its therapeutic uses.

Aloe-emodin is a naturally anthraquinone derivative and an active ingredient of Chinese herbs, such as Cassia occidentalis, Rheum palmatum L., Aloe vera, and Polygonum multiflorum Thunb. Emerging evidence suggests that aloe-emodin exhibits many pharmacological effects, including anticancer, antivirus, anti-inflammatory, antibacterial, antiparasitic, neuroprotective, and hepatoprotective activities. These pharmacological properties lay the foundation for the treatment of various diseases, including influenza virus, inflammation, sepsis, Alzheimer\'s disease, glaucoma, malaria, liver fibrosis, psoriasis, Type 2 diabetes, growth disorders, and several types of cancers. However, an increasing number of published studies have reported adverse effects of aloe-emodin. The primary toxicity among these reports is hepatotoxicity and nephrotoxicity, which are of wide concern worldwide. Pharmacokinetic studies have demonstrated that aloe-emodin has a poor intestinal absorption, short elimination half-life, and low bioavailability. This review aims to provide a comprehensive summary of the pharmacology, toxicity, and pharmacokinetics of aloe-emodin reported to date with an emphasis on its biological properties and mechanisms of action.

OBJECTIVE: Cassia absus is a plant of the family fabaceae with Ayurvedic ethnomedical records. It is used in traditional medicine for the treatment of bronchitis, asthma, cough, conjunctivitis, leucoderma, renal and hepatic diseases, constipation, tumors, venereal ulcer, headache, hemorrhoids and wound healing. Preliminary in vitro and in vivo studies have provided valuable scientific evidence for its use. This review aims to summarize reported pharmacognosy, traditional uses, phytochemistry and pharmacological potential of C. absus while identifying potential areas of further research of plant.
RESULTS: The review comprises literature pertaining to the evidence base therapeutic potential, pharmacognosy and phytochemistry of C. absus spanning from 1935 to 2016 using published articles in peer-reviewed journals, ethno botanical text books, and worldwide accepted scientific databases via electronic search (Elsevier, Google Scholar, PubMed, Scopus, Springer, Web of Science, Wiley online library). Kew Botanical Garden databases and the Plant List were used to authenticate the scientific names. Different pharmacological experiments in many in-vitro and in-vivo models have proved the potential of C. absus with antihypertensive, antifertility, antifungal, anti-inflammatory, anti-hyperglycemic, anti-glycation, antibacterial activity, α- amylase inhibitory activity, antioxidant and reducing activitity etc. chaksine, iso-chaksine, saturated and unsaturated fatty acids, chrysophanol, aloe-emodin and a wide range of chemical compounds have also been reported. Toxicity studies reveal the nontoxic nature of C. absus at a dose of 2000 mg/kg, however, plant possess reproductive toxicity and can be used as birth control or abortifacient.
CONCLUSIONS: Reported activities suggest that there is sufficient pharmacological potential for developing C. absus as a drug for hypertension, infections, diabetes and its complications. However, heterogeneity in study protocol and conflicting results mask the ability to replicate these studies. So, future studies should be replicated in line with best practices. More toxicological studies would aid the progress to clinical trial studies. Various ethno medical uses of C. absus have not been evaluated yet.

Cassia is a large tropical genus with about 600 species that have been widely used as folk medicines in China and India. This genus has been known to possess various biological activities, e.g. antimicrobial, anti-inflammatory, antioxidant, anti-malarial, anti-mutagenic activity, and anti-fertility etc. Flavonoids, for its broad spectrum of pharmacological activity and low toxicity, have attracted more interest in the development and utilization of natural medicines. The structure and biological activity research of flavonoids extracted from Cassia genus is the first step in the search for new drugs from those plants. This review summarizes the isolation and characterization of flavonoids from various Cassia species, such as Cassia absus, Cassia alata, Cassia fistula, etc. Flavonoids can be extracted from different parts of the plants, such as seed, leaf, stem and pod. Chemical structure research of these flavonoids in extracts has revealed many different types of compounds, which show the complication of the metabolism of Cassia genus. The antidiabetic activities can be found in many Cassia species. The efficiency of extraction method and action mode have been widely investigated. The extract not only can reduce the blood glucose level, but also improve glycogen content. Research show that the methanolic extract is effective in inducing hypoglycemic effects in both type I and II diabetes. Because flavonoids have complex structures, various function points, and unknown pertinence and selectivity for different health conditions, there are still many research areas waiting to be explored, such as to reveal the metabolic pathways of flavonoids in the Cassia genus, and to illustrate the structure-activity relationship between flavonoids and protein. That above-mentioned research will provide the basis for further medicinal development on this genus.

Anthranoid laxatives are widely used laxatives of natural origin. Because of their chemical structure they are carried unabsorbed to the large bowel, where metabolism to the active aglycones takes place. These aglycones exert their laxative effect by damaging epithelial cells, which leads directly and indirectly to changes in absorption, secretion and motility. Damaged epithelial cells can be found as apoptotic bodies in the pigmented colonic mucosa, characteristic for pseudomelanosis coli. Pseudomelanosis coli is a condition caused by chronic (ab)use of anthranoid laxatives and has recently been associated with an increased risk of colorectal carcinoma. In vitro and animal studies have shown a potential role of anthranoid laxatives in both the initiation and promotion of tumorigenesis. Studies in humans have also suggested tumour promoting activities for these laxatives. Although the short-term use of these substances is generally safe, long-term use cannot be recommended.
