Cedrelopsis grevei Baill. (Ptaeroxylaceae) trunk bark extract is empirically used in Madagascar against several pathologies, from persistent catarrh to hypertension. The effect C. grevei extract on age-related changes in systolic blood pressure (SBP) and endothelial function was investigated. Rats (90-100 week-old) received treatment either with C. grevei extract (80 mg kg(-1)) or vehicle for 8 weeks. SBP was evaluated by tail-cuff and vascular reactivity and endothelial vasodilatation of both aortae and small mesenteric arteries (SMA) were assessed by acetylcholine (ACh) in the presence or in the absence of either reactive oxygen species (ROS) scavengers superoxide dismutase (SOD) plus catalase or the nitric oxide synthase inhibitor, NG-L-arginine methyl ester (L-NAME). Plasma nitric oxide (NO) was evaluated by nitrite assay and expressions of eNOS, Cu/Zn-, Mn- and EC-SOD were determined by Western Blot. C. grevei administration prevented the increase of SBP and improved endothelium-dependent relaxations in aortae and SMA from aged rat via increased NO and decreased participation of ROS. Furthermore, C. grevei treatment enhanced plasma nitrite content but did not modify eNOS, Cu/Zn-, Mn- or EC-SOD expressions in the two arteries studied. These results suggest that C. grevei prevents both increased blood pressure and age-related endothelial dysfunction supporting the empirical use of C. grevei trunk bark extract against mild hypertension often associated with aging.

The present study evaluates the possible hypoglycemic activity and ameliorative effects of oral administration of ethanol extracts (EEBC) and butanol fraction (BFBC) of Buchholzia coriacea seeds, a plant in use traditionally for treating diabetes, hypertension, rheumatism, cold, cough and catarrh, in streptozotocin (STZ)-induced diabetic mice and rats. Fasting blood glucose (FBG) levels were evaluated before and after extracts administration. EEBC and BFBC significantly decreased (P<0.05) FBG in hyperglycemic mice and normoglycemic rats within 4 and 12 h, respectively after extract administration. The administration of EEBC, BFBC and glibenclamide (a standard antidiabetic drug) for 10 days significantly lowered (P<0.05) FBG level in STZ-induced diabetic rats by 55%, 64% and 56%, respectively. EEBC and BFBC significantly (P<0.05) decreased hepatic injury induced by STZ as evident in the decreased activity of serum alanine amino transferase and aspartate amino transferase compared to in the STZ-only treated group. Similarly, both extracts significantly decreased (P<0.05) the elevated levels of serum creatinine, urea, total cholesterol, triglyceride and thiobarbituric acid reactive species (TBARS) products in diabetic rats. Serum superoxide dismutase activity was significantly enhanced (P<0.05) by treatments with EEBC, BFBC and glibenclamide. Overall, the results suggest that B. coriacea seeds contain a potent hypoglycemic and antioxidant agent suggested to be a flavone glycoside concentrated in BFBC which may find clinical application in amelioration of diabetes-induced secondary complications.

The rhizomes of Zingiber officinale Roscoe (Zingiberaceae), commonly known as ginger is an important kitchen spice and also possess a myriad health benefits. The rhizomes have been used since antiquity in the various traditional systems of medicine to treat arthritis, rheumatism, sprains, muscular aches, pains, sore throats, cramps, hypertension, dementia, fever, infectious diseases, catarrh, nervous diseases, gingivitis, toothache, asthma, stroke and diabetes. Ginger is also used as home remedy and is of immense value in treating various gastric ailments like constipation, dyspepsia, belching, bloating, gastritis, epigastric discomfort, gastric ulcerations, indigestion, nausea and vomiting and scientific studies have validated the ethnomedicinal uses. Ginger is also shown to be effective in preventing gastric ulcers induced by nonsteroidal anti-inflammatory drugs [NSAIDs like indomethacin, aspirin], reserpine, ethanol, stress (hypothermic and swimming), acetic acid and Helicobacter pylori-induced gastric ulcerations in laboratory animals. Various preclinical and clinical studies have also shown ginger to possess anti-emetic effects against different emetogenic stimuli. However, conflicting reports especially in the prevention of chemotherapy-induced nausea and vomiting and motion sickness prevent us from drawing any firm conclusion on its effectiveness as a broad spectrum anti-emetic. Ginger has been shown to possess free radical scavenging, antioxidant; inhibition of lipid peroxidation and that these properties might have contributed to the observed gastroprotective effects. This review summarizes the various gastroprotective effects of ginger and also emphasizes on aspects that warranty future research to establish its activity and utility as a gastroprotective agent in humans.

Traditional medicine scientists believed that sleeping under the stars and moonlight is not healthy because it brings about nose bleeds and respiratory problems. In Avicenna's view, the spirit and its tendency to the light are introduced as main etiology, which cannot explain star light as a proper etiology. In modern knowledge, it seems cosmic rays that reach our planet's atmosphere by electron cascade, play a key role. Internal organs' electrical charge distribution disturbance caused by these electrons can lead to irregular spasms in the muscular walls of arteries and other organs. These interactions may finally lead to circulation (epistaxis and hypertension) and respiratory (catarrh) problems.
