As the most widely used illicit drug worldwide, and as a source of numerous under-studied pharmacologically-active compounds, a precise understanding of variability in psychological and physiological effects of Cannabis varieties is essential. The National Institute on Drug Abuse (NIDA) is designated as the sole legal producer of Cannabis for use in US research studies. We sought to compare the chemical profiles of Cannabis varieties that are available to consumers in states that have state-legalized use versus what is available to researchers interested in studying the plant and its effects...

Cinnamon has many health improving compounds such as proanthocyanidins, which also have potential for the prevention of damages caused by diabetes. Similarly, α-tocopherol is a natural antioxidant with important role on protection of fatty acids in membranes and lipoproteins. However, the addition of antioxidants in food may result in interaction with food matrix, low stability and unpleasant taste. In the present study, a proanthocyanidin-rich cinnamon extract (PRCE) (Cinnamomum zeylanicum) was co-encapsulated with α-tocopherol into solid lipid microparticles (SLMs) by spray chilling...

Intestinal fibrosis, a complication of inflammatory bowel disease, is currently being addressed by surgery alone, with no adequate alternative therapy available for patients. We propose that anti-inflammatory plant substances like cinnamon extract (CE) or its main compound cinnamaldeyde (CA) could aid in therapy. We recently found CE reducing inflammation in murine colitis. Here, we analysed effects of CE on fibrosis in IL-10(-/-) colitis METHODS AND RESULTS: IL-10(-/-) and wild type (wt) mice were orally treated with/without vehicle or CE...

The aim of the present study was to investigate the role of myristicin (Myr; 1‑allyl‑5‑methoxy‑3,4‑methylenedioxybenzene), an active aromatic compound isolated from nutmeg, carrot, basil, cinnamon and parsley, in hypoxia‑induced apoptosis in rat dorsal root ganglion (DRG) neurons. It was observed that Myr significantly enhanced cell viability in hypoxia‑induced DRG neurons in a dose‑dependent manner; the optimal concentration of Myr was 50 µM. Furthermore, Myr reduced the percentage of deoxynucleotidyl transferase‑mediated dUTP nick end‑labeling‑positive neuronal cells and influenced the expression of the pro‑apoptotic gene B‑cell lymphoma 2 (Bcl‑2) associated X protein, the apoptosis protease cleaved caspase‑3 and the anti‑apoptotic gene Bcl‑2, in the hypoxia‑induced group...
