Paeonol is a naturally existing bioactive compound found in the root bark of Paeonia suffruticosa and it is traditionally used in Chinese medicine for the prevention and management of cardiovascular diseases. To date, a great deal of studies has been reported on the pharmacological effects of paeonol and its mechanisms of action in various diseases and conditions. In this review, the underlying mechanism of action of paeonol in cardiovascular disease has been elucidated. Recent studies have revealed that paeonol treatment improved endothelium injury, demoted inflammation, ameliorated oxidative stress, suppressed vascular smooth muscle cell proliferation, and repressed platelet activation. Paeonol has been reported to effectively protect the cardiovascular system either employed alone or in combination with other traditional medicines, thus, signifying it could be a hypothetically alternative or complementary atherosclerosis treatment. This review summarizes the biological and pharmacological activities of paeonol in the treatment of cardiovascular diseases and its associated underlying mechanisms for a better insight for future clinical practices.

We previously evaluated the biochemical changes induced by the local product TCM for diabetes (TCM-D™) on blood glucose levels and other biochemical changes in normal mice fed orally with the recommended human dose (30 ml/kg daily) and ten times this dose for eight weeks. TCM-D™ is an aqueous extract of the roots of Trichosanthes kirilowii Maxim, Paeonia lactiflora Pall, Glycyrrhiza uranlensis Fisch. and Panax ginseng Meyer (red) combined at the dry weight proportions of 36%, 28%, 18% and 18% respectively. The study showed that at these dosages the blood glucose levels as well as the body weights in treated mice were significantly reduced when compared with pretreatment values and control animals. The present study evaluated the effect of the extract in a mouse model of Type 1 diabetes mellitus.

Fulltext Therapeutic roles of natural remedies in combating hereditary ataxia: A systematic review

BACKGROUND: Hereditary ataxia (HA) represents a group of genetically heterogeneous neurodegenerative diseases caused by dysfunction of the cerebellum or disruption of the connection between the cerebellum and other areas of the central nervous system. Phenotypic manifestation of HA includes unsteadiness of stance and gait, dysarthria, nystagmus, dysmetria and complaints of clumsiness. There are no specific treatments for HA. Management strategies provide supportive treatment to reduce symptoms.
OBJECTIVES: This systematic review aimed to identify, evaluate and summarise the published literature on the therapeutic roles of natural remedies in the treatment of HA to provide evidence for clinical practice.
METHODS: A systematic literature search was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Web of Science, PubMed and Science Direct Scopus were thoroughly searched for relevant published articles from June 2007 to July 2020.
RESULTS: Ten pre-clinical and two clinical studies were eligible for inclusion in this systematic review. We identified the therapeutic roles of medicinal plants Brassica napus, Gardenia jasminoides, Gastrodia elata, Ginkgo biloba, Glycyrrhiza inflata, Paeonia lactiflora, Pueraria lobata and Rehmannia glutinosa; herbal formulations Shaoyao Gancao Tang and Zhengan Xifeng Tang; and medicinal mushroom Hericium erinaceus in the treatment of HA. In this review, we evaluated the mode of actions contributing to their therapeutic effects, including activation of the ubiquitin-proteasome system, activation of antioxidant pathways, maintenance of intracellular calcium homeostasis and regulation of chaperones. We also briefly highlighted the integral cellular signalling pathways responsible for orchestrating the mode of actions.
CONCLUSION: We reviewed the therapeutic roles of natural remedies in improving or halting the progression of HA, which warrant further study for applications into clinical practice.

Traditionally, in Chinese medicine, tree peony and apple flower buds are used to prepare herbal decoctions to cure various ailments. As both of these flowers are popular and used regularly, providing scientific evidence on their basic composition is a necessity. Hence, in the present study, we report the chemical composition of these two flower buds. Results revealed tree peony and apple flower buds to have high crude protein (15.73 and 26.30%), fibre (13.11 and 16.51%), and carbohydrate (57.84 and 40.63%) contents. Both the flowers had significant amounts of essential amino acids and unsaturated fatty acids. Essential minerals present in tree peony and apple flowers were potassium (1540.37 and 1125.60 mg/100 g), calcium (462.46 and 449.98 mg/100 g), magnesium (241.51 and 164.23 mg/100 g), sodium (12.75 and 20.06 mg/100 g), and phosphorus (420.00 and 590.00 mg/100 g), respectively. Heavy metals (cadmium, nickel, mercury, lead, and arsenic) were detected in trace amounts (< 0.50 mg/100 g) in both the flower buds. Results obtained indicate that both flowers could be exploited as an additional source of nutraceutical for the development of new functional foods.

Background: A number of Traditional Chinese Medicine (TCM) preparations are being used for the treatment of diabetes mellitus. Some components of these preparations have biochemical effects other than those of lowering blood glucose and indeed have been used for other medical indications in traditional practice. The primary objective of the study was to determine the effect of the oral mixture of Traditional Chinese Medicine for diabetes (TCM-D™ complex) on blood glucose level and the biochemical changes if any, on the liver (ALT, AST, gamma-GT, albumin, globulin) and renal (blood creatinine, urea) functions in normal mice. The oral mixture is an aqueous extract of four wellknown traditional Chinese medicinal herbs and consists of Trichosanthes kirilowii Maxim., Paeonia lactiflora Pall., Glycyrrhiza uranlensis Fisch., and Panax ginseng (red) CA Meyer in the proportion of 36%, 28%, 18%, and 18% respectively of the dry weight. These herbs have
been shown to have blood glucose lowering activity and have been used for other traditional medicinal purposes.The safety of the combination was evaluated in the present study. Methods: Experimental Balb/c mice were treated orally via gastric tube with the extract at daily doses equivalent to 1 and 10 times the recommended human dose for 8 weeks. Blood glucose and other biochemical profiles were monitored at pre-treatment and monthly posttreatment until killed. Results: When compared to pre-treatment levels, the blood glucose levels were significantly lower in treated animals compared to those in the control group. At the recommended TCM-D™ dose the levels in treated animals were significantly lower than that of control animals and at pre-treatment. When compared with pre-treatment, the glucose levels were lowest at Week 8 of treatment, the mean levels being 111.23%, 83.32% and 70.33% in control, and in animals given 1 x and 10 x the recommended TCM-D™ dosage respectively. The blood glucose lowering effect was also associated with a significant weight loss in treated animals. There were transient increases in AST and ALT levels but these reverted to normal at Week 8 of treatment. The levels of bilirubin, g-GT, albumin, creatinine and blood urea were also not significantly different at Week 8 from pre-treatment levels in all groups. Conclusion: Even at 10 times the dosage recommended for humans, TCM-D™ did not affect the liver and renal functions of treated animals. Treated and control animals remained healthy and normal throughout the period of observation.
