Ayurvedic Therapies to Target the Microbiome: Evidence and Possibilities.

Context: The microbiome is a constantly evolving entity, being influenced by diet, lifestyle, age, genetics, medication, and environment; keeping the microbiome in good health is a step toward better health for the body. Ayurveda emphasizes a healthy internal milieu that synchronizes with the circadian and seasonal rhythms, in addition to reacting to other stressors. Objective: The current review intended to provide an overview of Ayurvedic principles related to health and disease and their management and to briefly discuss the current understanding of the human microbiome and explore Ayurvedic herbs and therapies that have been studied for their effects on the microbiome. Design: The team included researchers in India and Canada. A Pubmed search was performed using the keywords Ayurveda therapies, Ayurvedic therapies, Gut microbiome, Panchakarma, Therapeutic purgation, Therapeutic emesis, medicated enema. Results: Research connecting Ayurvedic interventions and the gut microbiome is yet in a nascent stage. Several Ayurvedic herbs have been researched for their potential in altering the gut microbiome. Among the Ayurvedic therapies, virechana (therapeutic purgation) and basti (medicated enema) have been studied for their gut microbiome altering effects. However, the limited number of such studies prevents from drawing categorical conclusions currently, about the effects of Ayurvedic Panchakarma therapy on the human microbiome. Conclusions: Studying where and how the Ayurvedic herbs and therapies can exert their influence on the human microbiome provides a challenging yet novel opportunity and can help address multiple health and disease conditions.

Modulation of Cardiac Autonomic Dysfunction in Ischemic Stroke following Ayurveda (Indian System of Medicine) Treatment.

Objectives. Cardiac autonomic dysfunction in stroke has implications on morbidity and mortality. Ayurveda (Indian system of medicine) describes stroke as pakshaghata. We intended to study the effect of Ayurveda therapies on the cardiac autonomic dysfunction. Methods. Fifty patients of ischemic stroke (middle cerebral artery territory) (mean age 39.26 ± 9.88 years; male 43, female 7) were recruited within one month of ictus. All patients received standard allopathic medications as advised by neurologist. In addition, patients were randomized to receive physiotherapy (Group I) or Ayurveda treatment (Group II) for 14 days. Continuous electrocardiogram and finger arterial pressure were recorded for 15 min before and after treatments and analyzed offline to obtain heart rate and blood pressure variability and baroreflex sensitivity (BRS). Results were analysed by RMANOVA. Results. Patients in Group II showed statistically significant improvement in cardiac autonomic parameters. The standard deviation of normal to normal intervals,and total and low frequency powers were significantly enhanced (F = 8.16, P = 0.007, F = 9.73, P = 0.004, F = 13.51, and P = 0.001, resp.). The BRS too increased following the treatment period (F = 10.129, P = 0.004). Conclusions. The current study is the first to report a positive modulation of cardiac autonomic activity after adjuvant Ayurveda treatment in ischemic stroke. Further long term studies are warranted.
