Homeopathy: The Journal of the Faculty of Homeopathy

This paper discusses the nature of the active ingredient of homeopathic ultramolecular dilutions in terms of quantitative physics. First, the problem of the nature of an active ingredient in ultramolecular dilutions is analysed leading to the recognition of the necessity of characterizing the active ingredient as a non-local quality. Second, non-locality in quantum mechanics, which is used as a paradigm, is formally presented. Third, a generalization of quantum mechanics is considered, focussing on the consequences of weakening of the axioms.

A study to evaluate an antimutagenic potential of water, chloroform and acetone extracts of Triphala has been made in an Ames histidine reversion assay using TA98 and TA100 tester strains of Salmonella typhimurium against the direct-acting mutagens, 4-nitro-o-phenylenediamine (NPD) and sodium azide, and the indirect-acting promutagen, 2-aminofluorene (2AF), in the presence of phenobarbitone-induced rat hepatic S9. A combination drug 'Triphala' - a composite mixture of Terminalia bellerica, T.

As a chromatographic column, the high-speed counter-current chromatography system was equipped with a preparative HPLC series, enabling the successful isolation of hydrolysable tannins from the fruits of Terminalia chebula, a traditional Chinese medicine. The two-phase solvent system was composed of n-hexane-ethyl acetate-methanol-water (1:20:1:20 v/v). As a result, 33.2 mg chebulagic and 15.8 mg chebulinic acids were obtained in one step from 300 mg of crude extract. Their purities were determined by HPLC to be 95.3 and 96.1%, respectively.

The antibacterial activity of acetone, hexane, dichloromethane leaf extract of five Terminalia species (Terminalia alata Heyne ex Roth., Terminalia arjuna (Roxb.) Wt. and Am., Terminalia bellerica (Gaertn.) Roxb., Terminalia catappa L. and Terminalia chebula Retz.) were tested by Agar-well-diffusion method against human pathogens E. coli, Pseudomonas aeruginosa, Bacillus subtilis, Staphylococcus aureus and Staphylococcus epidermidis. The Rf values and relative activities of separated compounds were tested.

AIM: Many weapons are available in the arsenal of a dental professional to combat dental caries, which is almost ubiquitously present. From a public health perspective, most of these weapons are far from being an ideal drug. Hence, there is a demand for better and effective antibacterial agents. This factor stimulated the process of the present study. The aim of the study was to determine the effect of ethanol extract of Terminalia chebula on Streptococcus mutans. MATERIALS AND METHODS: Dried ripe fruits of Terminalia chebula were procured and powdered.

The thiazolidinedione (TZDs) class of drugs are very effective for the treatment of type 2 diabetes mellitus (T2DM). But due to the adverse effects of synthetic TZDs, their use is strictly regulated. The therapeutic actions of TZDs are mediated via modulation of peroxisome proliferator-activated receptor gamma (PPAR?). Naturally occurring PPAR? modulators are more desirable as they lack the serious adverse effects caused by TZDs. This has prompted the exploitation of medicinal plants used in traditional medicine, for their potential PPAR? activity.

BACKGROUND: Free radicals are implicated in several metabolic diseases and the antioxidant therapy has gained an utmost importance in the treatment. The medicinal properties of plants have been investigated and explored for their potent antioxidant activities to counteract metabolic disorders. In this study, the chemical composition and free radical scavenging potential of leaf gall extracts (ethanol, petroleum ether, chloroform and aqueous) of Terminelia chebula is evaluated, which is extensively used in the preparation of traditiona medications to treat various metabolic diseases.

A separation method based on high-speed counter-current chromatography (HSCCC) has been established for the isolation and preparation of gallic acid from the ethanol extract of Terminalia chebula Retz. After comparing five kinds of solvent protocols of HSCCC, the two-phase system of n-hexane-ethyl acetate-methanol-water (1:5:1:5, v/v/v/v) was finally chosen as the operating solvent of HSCCC for the separation of gallic acid, in which the lower phase was used as the mobile phase and the upper phase as stationary phase.

Context Chebulae Fructus is used as an herbal remedy for diarrhoea in traditional Chinese medicine. However, there is no scientific evidence to support its antidiarrhoeal activity. Objective This study evaluates the antidiarrhoeal properties of Chebulae Fructus aqueous extract (CFAE) and determines the active fraction. Materials and methods The antidiarrhoeal effect of CFAE (200-800?mg/kg) was investigated by determining the wet dropping, intestinal transit in BALB/c mice and enteropooling in Wister rats.

1 Various approaches to the treatment of adolescents who have developed long-term chronic dependency on the inhalation of solvent fumes are briefly outlined with regard to their effectiveness. 2 The importance of suggestion in the counselling relationship is emphasized as a feature which underlies the work of therapists from a wide range of systems of psychotherapy. 3 A method of treatment incorporating hypnosis is described and evaluated with reference to case reports.
