Purpose. Diabetes mellitus is characterized by hyperglycemia resulting from defects in insulin secretion, action or both. The use of medicinal plants for the treatment of diabetes mellitus dates back from the Ebers papyrus of about 1550 B.C. One of the major problems with herbal drugs is that the active ingredients are not well defined. It is important to know the active components and their molecular interactions which will help to analyze their therapeutic efficacy and also to standardize the product. There are a number of medicinal plants known for their anti-diabetic effect that possess similarities in their active chemical components, e.g. iridoid and secoiridoid glycosides. Methods. In this study, we have compared the structure of various iridoid and secoiridoid glycosides to design a novel pharmacophore. We further developed a structure-activity relationship for the inhibition of glycogen phosphorylase-a. Conclusion. By using docking studies, we are proposing, for the first time, that inhibition of glycogen phosphorylase-a activity is a common target for iridoids and secoiridoids to elicit anti-diabetic effects. This article is open to POST-PUBLICATION REVIEW.

Abnormally emanates from difficulty in insulin secretion, Diabetes mellitus (DM) is known to be a metabolic disorder that causes an increase of blood glucose in blood streams. The lack of effective modern treatments, the lifelong treatment with modern medicines, overtime, its associated health side effects, and its expensive prices among others are the challenging existing realities that devastate the health and economic burdens its sufferers, especially in developing nations. Today, this has prompted the search for cheap, safe, and reliable drugs from medicinal plants. This study reviewed existing information on medicinal plants used for the treatment of diabetes mellitus from various sources. Several documents (published and unpublished papers, books among others) were consulted in compilation of this review. It is found that there is a wide, yet uneven support for active components of major medicinal.

Diabetes mellitus (DM) is a chronic disease which has clinched the world. More than 300 million people of the world are suffering from this disease and the number is still increasing at a rapid rate as modern medical science has no permanent solution for the disease. Current scenario of the nutraceuticals has increased patient’s faith on the traditional medicinal system and world nutraceutical industry is estimated to reach $285.0 billion by 2021. The increasing trend of nutraceuticals in diabetes treatment makes it important to collect the traditional knowledge of medicines under one heading as it can help researchers to formulate new functional foods and nutraceuticals which can either lower down the risk or cure DM. In addition, the discussion of market available food products, their active components and possible health benefits can help the patients to understand the herbal medicines in a better way.

Diabetes mellitus (DM) is considered as one of the most common metabolic disorders affecting huge number of people worldwide. Despite the availability of large numbers of drugs in the market to treat the disease, there is still a need for new sources to deal with the problem and avoid side effects. In the pursuit of discovering safer and more effective anti-diabetic drugs, herbal and folk medicine drugs from regions all over the world have captured researchers’ interest. Middle Eastern and North African medicinal plants contain a variety of pharmacologically active components that have shown to possess promising anti-diabetic potential. However, few data have been reported about medicinal plants from these regions in comparison to plants from other regions. Anti-diabetic medicinal plants from the MENA (the Middle East and North Africa) region, their role in controlling DM, and suggested mechanisms for the anti-diabetic activity of some medicinal plants are discussed in this review. Many of these plants have not been fully investigated and characterized, yet they have great potential for further development as anti-diabetic drugs.

Diabetes mellitus (DM) is a chronic disease caused by inherited or acquired deficiency in insulin secretion and by decreased insulin secretion by the organ. Insulin deficiency causes the DM. Synthetic drugs are widely used in the treatment of diabetes, but they have some side effects. The antihyperglycemic and antihyperlipedemic effects of the plants are related to their ability to maintain pancreatic function. Medicinal plants constituents such as glycosides, alkaloids, terpenoids, and flavonoids mitigate DM. B. ciliata inhibits the α-glucosidase and α-amylase. Cinnamon extracts improve insulin receptor function by activating insulin receptor kinase and inhibiting insulin receptor phosphatase, which lead to an increase in insulin sensitivity. Morinda lucida also had the highest antioxidant activity, and it also inhibited the α-glucosidase. Many plants have also been shown to antihyperlipedemic effects. Finally, it can be concluded that medicinal plants have that ability to treat or prevent DM.

ABSTRACTObjective: to list the main medicinal plants used by ecological farmers from southern Rio Grande do Sul in the supplementary treatment of diabetes mellitus. Method: it was performed a study with qualitative approach of  exploratory and descriptive kind. The study subjects were farmers who sell their products at the ecological fair of Pelotas. Data were collected using semi-structured questionnaire. The interviews were recorded with consent of farmers and the plants were georeferenced and photographed for taxonomic  identification. The project was approved by the Ethics Committee of the Faculty of Medicine at 072/2007 opinion. Results: ten plants were mentioned in the treatment of diabetes mellitus. According to the literature, six of them had positive results in animals or humans as hypoglycemiants, and the other plants are indicated to treat various other symptoms. Conclusion: medicinal plants can act as an adjuvant of the medicamentous therapy in reducing glicemy of the disease carriers, taking into account the legal and safe precepts for using and importance of nurses in advising on the correct use of these therapies.
