India leads the world with maximum number of diabetes patients being termed as the "diabetes capital of the world." Certain risk factors including unsatisfactory diet, overweight, and a sedentary lifestyle are potentially reversible. Acharayas have widely described the role of diet and activities to control Madhumeha (type 2 diabetes mellitus [T2DM]) along with medications. Habitual consumption of roasted or dry Barley (Hordeum vulgare L.) flour, Mudga (Phaseolus aureus Roxb.) and Amalaki (Emblica officinalis Gaertn.) prevents the manifestation of Prameha.

Amalaki rasayana was prepared fresh and healthy aged randomized human volunteers were administrated with either rasayana or placebo for 45 days strictly as per the traditional text. The DNA repair was analyzed in peripheral blood mononuclear cells before and after rasayana administration and after 45 days post-rasayana treatment regimen. UVC-induced DNA strand break repair (DSBR) based on extent of DNA unwinding by fluorometric analysis, nucleotide excision repair (NER) by flow cytometry and constitutive base excision repair (BER) by gap filling method were analyzed.

The research team fed all mice, except those in a control group (ND), a HFD for 10 weeks beginning at 7 weeks of age, supplementing the HFDs with herbal treatments for 4 of the groups. The team divided the mice into six weight-matched groups of seven mice each: (1) normal diet (ND), (2) high-fat diet (HFD), (3) triphala (HFD+T), (4) amalaki (HFD+A), (5) haritaki (HFD+H), and (6) bibhitaki (HFD+B).

Earlier we showed formulation-specific beneficial effects of dietary supplement of Ayurvedic Amalaki Rasayana (AR, a herbal formulation) and Rasa-Sindoor (RS, a mercury-based organo-metallic formulation) on various biological parameters in Drosophila, parallel to traditional Ayurvedic literature. These formulations also suppressed cell death and pathology in fly models of neurodegeneration. To understand basis of inhibition of apoptosis, we examined effects of AR and RS on induced and developmental apoptosis in Drosophila. Dietary AR or RS significantly reduced apoptosis induced by GMR-GAL4-, sev-GAL4- or hs-GAL4-directed expression of Rpr, Hid or Grim (RHG) proapoptotic proteins or by GMR-GAL4-directed DIAP1-RNAi, resulting in significant restoration of organism's viability and eye morphology. AR or RS supplement enhanced levels of inhibitor of apoptosis proteins, DIAP1 and DIAP2, and of Bancal/Hrb57A, while the levels of RHG proteins and of initiator Dronc and effecter Drice caspases were reduced in non-apoptotic wild type as well as in RHG over-expressing tissues. Levels of Dronc or Drice remained unaffected in cells developmentally destined to die so that developmental apoptosis occurred normally. Elevated levels of DIAPs and reduced levels of RHG proteins and caspases reflect a more robust physiological state of AR or RS fed organisms allowing them to tolerate greater insults without triggering the cell-death response. Such homeostatic effects of these Rasayanas seem to contribute to 'healthy ageing', one of their effects suggested in traditional Ayurvedic practices.

A randomized controlled open clinical trial was conducted at Institute for Post Graduate Teaching and Research in Ayurveda, Jamnagar. Iron deficient anemic patients (n = 25) having Hb <12g% in females and 13g% in males and S.Iron <50mg/dl were selected and divided into two groups. Group A was given 2 g of Amalaki Rasayana thrice a day with unequal quantity of honey and ghee for 45 days, while Group B was given 150 mg ferrous fumarate + 1500 mcg folic acid (standard control) once a day with water for 45 days. Assessment was done on the basis of relief in cardinal symptoms of Pandu and hematological parameters.

In Ayurvedic classics, the symptom fever is considered as a separate disease called Jwara. Acharya Sushruta has mentioned Amalakyadi Gana for treatment of all types of Jwara, which contains four drugs namely Amalaki (Emblica officinalis Gaertn.), Haritaki (Terminalia chebula Retz.), Pippali (Piper longum L.), and Chitraka (Plumbago zeylenica L.).

The research team obtained 42 fertile, male, Swiss albino mice, weighing 20 g each, and housed them individually in an approved small-animal facility, in a pathogen-free environment. The team generated DIO mice by feeding them a HFD.

The research team's results showed that mice fed a HFD for a 10-week period, supplemented with herbal preparation(s) of triphala or its constituents, resulted in significant reductions in body weight (P < .0001), energy intake, and percentage of body fat (P < .001), as compared with mice in the HFD group. Herbal treatment significantly improved the lipid profiles of the mice by lowering serum total cholesterol (Total-C), TG, and low-density lipoprotein cholesterol (LDL-C) and increasing levels of high-density lipoprotein cholesterol (HDL-C) as compared to the mice in the HFD group. The research team also found that herbal treatment attenuated glucose levels, oral glucose tolerance as measured by the oral glucose tolerance test (OGTT), and levels of ALT. In addition to treatment with its three individual components, treatment with a popular Ayurvedic formulation of triphala also reversed the pathological changes in liver tissue and decreased the relative weight of visceral adipose fat pads.
