Despite concerted programmatic efforts iron deficiency anemia (IDA) continues to be a global health problem. Per Ayurveda, an Indian Traditional Medical System, natural plant materials such as pomegranate juice (PJ) is indicated as a food supplement to manage IDA. We hypothesized that pomegranate could play a role in improving absorption and assimilation of iron. A cell free in vitro model simulating the gastric and intestinal digestive processes coupled with cell based (Caco-2 and HepG2) models were used to assess iron (FeSO4 form) dialysability in the presence of PJ. Iron assimilation into cells was measured in terms of the cellular ferritin content. PJ (containing ~13 mg/100 ml natural ascorbic acid equivalent) increased the dialysability of iron by >3 fold when compared to control in the cell free model. An equivalent concentration of ascorbic acid alone increased it only by 1.6-fold. PJ increased the iron uptake in Caco2 cells by ~6-fold and ferritin content by 30% when compared to the ascorbic acid control. Similarly, PJ enhanced the iron uptake in HepG2 cells by ~3 fold and iron assimilation by about 50%. This study establishes a scientific evidence for Ayurveda’s claim of using pomegranate in the management of IDA by facilitating iron absorption and assimilation. It provides a simple solution for addressing the global problem of IDA. Synergistic action of multiple phytochemicals, over and above ascorbic acid, in PJ may be responsible for improving iron bioavailability.

Ethnopharmacological relevance Diabetes is a multifactorial disease with complex multi-organ-multi-target crosstalk in the body. Currently, the theoretical assumptions framing the diabetes management strategies are reductionist and largely focus on reducing hyperglycemia through targeted molecular drugs. While they effectively reduce hyperglycemia, they are inadequate to address the multifactorial etiopathology, chronicity and systemic complications of diabetes. Therefore, a holistic and systemic approach is essential for its successful management. We hypothesize an integrative diabetes management strategy, combining holistic principles of diabetes management with its molecular understandings, would be more appropriate to fill this gap. The holistic disease management principles of Ayurveda, the Indian system of medicine, can play a pivotal role in this context. This narrative review discusses the scope of a trans-disciplinary ‘ Ayurveda-Biology ’ approach for deepening the holistic understanding of the pathophysiology of diabetes as well as designing novel integrative strategies for managing diabetes and restoring whole body glucose homeostasis. Methodology The article analyses the Ayurveda scheme of diabetes management and correlates it with the molecular understanding of its pathophysiology and management. The sources of information used in this article include classical texts of Ayurveda , medical books, published research articles and scientific databases like PubMed, Google Scholar, Science-Direct, etc. Results While Ayurveda and modern biomedicine uses different epistemology and ontology for describing diabetes, both the systems recognize the central role of gut and gut derived factors in postprandial glucose disposal and whole body glucose homeostasis. Essentially, the principles of both Ayurveda and modern biomedicine overlap at a gut centred view of diabetes management; and Gastro-intestinal mediated glucose disposal , a holistic concept of glucose metabolism, is emerging as a converging node for designing innovative integrative diabetes management strategies. Conclusions An integrative disease management strategy, combining holistic and reductionist perspectives of traditional medicine and biology respectively, would be the prerogative for successful management of diabetes. Creating an ‘ Ayurveda-Biology’ knowledge framework integrating the patient centred holistic management principles of Ayurveda and the molecular approaches of modern biology can give better insights into the biology of whole body glucose homeostasis and offer novel strategies for cost effective, holistic and multi-targeted management of diabetes.

Background The patho-physiological cross-talk between diabetes and obesity is well established. However, the choices of drugs suitable for combined treatment of diabetes and obesity are limited. Integration of complementary and alternative medicines (CAMs), like Ayurveda, with modern medicine would be a promising strategy to fill this gap. The diagnostic principles of Ayurveda define obesity as one of the predisposing factors of Madhumeha (correlated as diabetes) and recommends specific formulations for managing obese-diabetes. Lodhrasavam is one such poly-herbal formulation prescribed for obese-diabetic patients. Objectives The present study is an attempt to demonstrate the possible modes of action of Lodhrasavam, built on the hypothesis that the formulation can exert both anti-diabetic and anti-obesity actions. Materials and methods Lodhrasavam, following simulated gastro-intestinal digestion, was monitored for inhibition of α-amylase, α-glucosidase (key digestive enzyme targets of anti-diabetic drugs) and adipogenesis using standard in vitro model systems. Results Lodhrasavam digest inhibited α-amylase (90%) and α-glucosidase (78%) activity as well as reduced the differentiation of 3T3-L1 fibroblasts to adipocytes. Upon fractionation, the enzyme inhibitory activity and anti-adipogenic activity of the digest were found distributed in different solvent fractions. This partly indicates a potential pharmacological networking of chemically and functionally diverse bioactive molecules in Lodhrasavam. Conclusion The study provides a possible mode of action and an experimental support for the Ayurvedic use of Lodhrasavam for managing obese-diabetes. Generating scientific evidences and understanding the modes of action, in contemporary scientific language, would essentially help in expanding global acceptance of potentials of CAMs in the management of life style disorders.

Medicinal herbs are one of the imperative sources of drugs all over the world. Star anise (Illicium verum), an evergreen, medium-sized tree with star-shaped fruit, is an important herb with wide distribution throughout southwestern parts of the Asian continent. Besides its use as spice in culinary, star anise is one of the vital ingredients of the Chinese medicinal herbs and is widely known for its antiviral effects. It is also the source of the precursor molecule, shikimic acid, which is used in the manufacture of oseltamivir (Tamiflu®), an antiviral medication for influenza A and influenza B. Besides, several other molecules with numerous biological benefits including the antiviral effects have been reported from the same plant. Except the antiviral potential, star anise possesses a number of other potentials such as antioxidant, antimicrobial, antifungal, anthelmintic, insecticidal, secretolytic, antinociceptive, anti-inflammatory, gastroprotective, sedative properties, expectorant and spasmolytic, and estrogenic effects. This review aimed to integrate the information on the customary attributes of the plant star anise with a specific prominence on its antiviral properties and the phytochemical constituents along with its clinical aptness.

Introduction Diabetic patients often consume traditional medicines, available as over-the-counter products, concurrently with prescribed conventional medicines. A study of 180 marketed Ayurvedic antidiabetic formulations showed that Enicostema axillare subsp. littorale (Blume) A.Raynal (Mamajjakah) is being used frequently in several formulations by Ayurvedic industry, particularly from the Western India. The present overview covers the classical and current literature on the plant for its antidiabetic activity. Materials and methods: The classical Ayurvedic literature, the current texts of Dravyaguna Vidnyan, Ayurvedic journals as well as pharmacological literature on E. axillare have been reviewed for its Ayurvedic Dravyaguna rationale and antidiabetic activity. Results: The earliest description of the plant E. littorale has been found in Shodhal Nighantu (12th Century) with its various synonyms and its use as an antipyretic and anthelminthic drug. Medicinal properties of the plant in classical and other texts reveal that it can best be described as laghu (light), ruksha (dry), of tikta rasa (pungent taste), ushna veerya (hot potency) and katu vipak (after-effects like pungent taste). It ameliorates pitta and kapha doshas. Its main site of action is medodhatu (adipose tissue) having pramehaghna (antidiabetic) properties. The phytochemical studies show major molecules that have shown antidiabetic properties are swertiamarin, apigenin and isovitexin. Several in vitro studies have demonstrated its antioxidant and anti-inflammatory activities; while in vivo studies have shown antidiabetic, antihyperlipidemic, antihypertensive, antiobesity, nephroprotective, hepatoprotective as well as antioxidant and anti-inflammatory activities. Several clinical studies have reported safety and antidiabetic activity in diabetic as well as prediabetics patients. Besides these, the plant has also shown nephroprotective, genoprotective activities as well as insulin sensitization. Conclusions: Wide use of E. axillare in diabetes mellitus suggests a need for thorough survey of its Ayurvedic pharmaco-epidemiology and drug utilization. The emergent data would facilitate Reverse Pharmacological study of the plant in diabetic patients. There is a potential for developing a safe and validated phytopharmaceutical antidiabetic drug.

Osteoporosis is one of the major metabolic bone diseases and is among the most challenging noncommunicable diseases to treat. Although there is an increasing interest in identifying bioactive molecules for the prevention and management of osteoporosis, such studies principally focus only on differentiation and mineralization of osteoblasts or inhibition of osteoclast activity. Stimulation of osteoblast migration must be a promising osteoanabolic strategy for improved metabolic bone disease therapy. In this study, we show that an anthraquinone derivative, aurantio-obtusin, stimulated chemotactic migration of MC3T3-E1 osteoblast cells in a concentration-dependent manner. The use of a real-time chemotaxis analyzing system, TAXIScan, facilitated the evaluation of both velocity and directionality of osteoblast migration in response to the compound. Besides migration, the compound stimulated osteoblast differentiation and mineralization. Taken together, the data presented in this paper demonstrate that aurantio-obtusin is a promising osteoanabolic compound of natural origin with potential therapeutic applications in the prevention of osteoporosis and other metabolic bone diseases.

Ethnopharmacological relevance Ayurveda has its unique perceptions and resultant methodologies for defining and treating human diseases. Fumigation therapy is one of the several treatment methods described in Ayurveda whereby fumes produced from defined drug formulations are inhaled by patients. This therapeutic procedure offers promising research opportunities from phytochemical and ethnopharmacological viewpoints, however, it remains under-noticed. Considering these facts, this review is primarily aimed at introducing said Ayurvedic fumigation therapy and discussing its scientific gaps and future challenges. Methodology A search of multiple bibliographical databases and traditional Ayurvedic text books was conducted and the articles analyzed under various key themes, e.g., Ayurvedic fumigation, fumigation therapy, medicinal fumigation, inhalation of drugs and aerosol therapy. Result Ayurveda recommends fumigation as a method of sterilization and therapeutic procedure for various human diseases including microbial infections and psychological disorders. However, it has not gained much attention as a prospective field with multiple research opportunities. Conclusion It is necessary to have a more detailed and systematic investigation of the phytochemical and pharmacodynamic properties of Ayurvedic fumigation therapy in order to facilitate the identification of novel bioactive compounds and more effective drug administration methods.
