The imbalance of hydrophilicity, and lipophilicity along with, a large molecular size (due to a unique chemical structure) of natural compounds, or plant actives pose a significant challenge for their absorption through a biological membrane and thus, alters the therapeutic efficacy. Therefore, it is desirable to have a novel approach for such formulation in order to improve the solubility and bioavailability, of these phytoconstituents as a phospholipid complexation. Herbal drugs are precisely, embedded and bound by phospholipids to form vesicular structures, which are amphoteric in nature...

Leptadenia reticulata (Retz.) Wight & Arn. (Apocynaceae), is a traditional medicinal plant species widely used to treat various ailments such as tuberculosis, hematopoiesis, emaciation, cough, dyspnea, fever, burning sensation, night blindness, cancer, and dysentery. In Ayurveda, it is known for its revitalizing, rejuvenating, and lactogenic properties. This plant is one of the major ingredients in many commercial herbal formulations, including Speman, Envirocare, Calshakti, Antisept, and Chyawanprash. The therapeutic potential of this herb is because of the presence of diverse bioactive compounds such as α-amyrin, β-amyrin, ferulic acid, luteolin, diosmetin, rutin, β-sitosterol, stigmasterol, hentricontanol, a triterpene alcohol simiarenol, apigenin, reticulin, deniculatin, and leptaculatin...

BACKGROUND: Recurrent miscarriage affects 1% to 3% of women of reproductive age and mostly occurs before the 10th week of gestation (and around the same gestational week in subsequent miscarriages). Although most pregnant women may not recognise a miscarriage until uterine bleeding and cramping occur, a repeat miscarriage after one or more pregnancy loss and the chance of having a successful pregnancy varies. To date, there is no universally accepted treatment for unexplained recurrent miscarriage...

Ayurveda is a major traditional system of Indian medicine that is still being successfully used in many countries. Recapitulation and adaptation of the older science to modern drug discovery processes can bring renewed interest to the pharmaceutical world and offer unique therapeutic solutions for a wide range of human disorders. Eventhough time-tested evidences vouch immense therapeutic benefits for ayurvedic herbs and formulations, several important issues are required to be resolved for successful implementation of ayurvedic principles to present drug discovery methodologies...

The development of traditional Chinese medicine lies in its significant clinical efficacy which is closely related to the bioavailability of drugs. The nature of the material foundation of compounds of traditional Chinese medicine is reflected in multi-component. As for the nature of components themselves, the level of their bioavailability depends on the biopharmaceutical properties, namely solubility and permeability, to a great extent. Therefore, under the guidance of the theory of traditional Chinese medicine and in the combination with modern preparation techniques, this essay reveals key techniques capable of improving the biopharmaceutical properties of components, in the hope of enhancing the clinical efficacy of components of traditional Chinese medicine...

The moisture content present in human skin makes it look young and the use of moisturizer results in fastening the moisture with a surface film of oil. Acne vulgaris is one of the most commonly seen diseases among the youth. The present study is focused on the use of herbs as moisturizer for acne treatment. The anti-acne moisturizer was formulated from herbal crude extracts and investigated the physico-chemical parameters as well as antibacterial activity of the formulation. The study revealed that ethanol extract of Andrographis paniculata, Glycyrrhiza glabra, Ocimum sanctum, Azadiracta indica and Green tea possessed the potential for inhibiting acne...

The aim of this work was to investigate the plug formation and filling properties of powdered herbal leaves using hydrogenated cotton seed oil as an alternative lubricant. In a first step, unlubricated and lubricated herbal powders were studied on a small scale using a plug simulator, and low-force compression physics and parameterization techniques were used to narrow down the range in which the optimum amount of lubricant required would be found. In a second step these results were complemented with investigations into the flow properties of the powders based on packing (tapping) experiments to establish the final optimum lubricant concentration...

The complex chemical composition of herbal medicine leads to the lack of appropriate method for identifying active compounds and optimizing the formulation of herbal medicine. One of the most commonly used method is bioassay-guided fractionation. However, if the herbal medicine was divided into many fractions, it would cost much money and time in carrying out such a full bioassay. So, can we just perform the bioassay of a few fractions, and then develop a method to predict the bioactivities of other fractions? This study is designed to try to answer the question...

Herbal injections are powerful preparations of traditional Chinese medicines. However, the quality control (QC) of these formulations is difficult to establish. Recently, chemical fingerprinting (CF) has been recommended as a potential strategy for the QC of herbal injections. However, some constituents cannot be detected by chromatographic methods. To establish a comprehensive QC process, biological fingerprinting (BF) was combined with CF to detect the fluctuation in quality of a herbal injection from chemical and biological aspects...

BACKGROUND: The discovery and development of new anti-malarials are at a crossroads. Fixed dose artemisinin combination therapy is now being used to treat a hundred million children each year, with a cost as low as 30 cents per child, with cure rates of over 95%. However, as with all anti-infective strategies, this triumph brings with it the seeds of its own downfall, the emergence of resistance. It takes ten years to develop a new medicine. New classes of medicines to combat malaria, as a result of infection by Plasmodium falciparum and Plasmodium vivax are urgently needed...

A sensitive LC/MS method was established to investigate the in vivo metabolism of GuanXin II prescription, a five-component Chinese herbal medicine formulation. Rat plasma, bile, urine, and feces were collected and analyzed following oral administration of the water decoction. A total of 50 compounds were identified, including 17 prototypes and 33 metabolites underwent methylation, oxidation, hydrolysis, sulfate conjugation, glucuronide conjugation, and glutathion conjugation. In addition, the component herb of the formulation from which the metabolites were derived was also identified...

BACKGROUND: In view of the high rates of off-label and unlicensed prescribing of drugs in children, the US Food and Drug Administration and the European Union have implemented legislative regulations for the pharmaceutical industry to increase the number of drugs with approved pediatric labeling. However, the extent to which the effects of pharmaceutical technologic aspects of pediatric oral drugs (eg, taste, route and frequency of administration, user instructions) on patient-related outcomes (eg, efficacy, tolerability, preference, adherence) can be based on clinical evidence from the available literature is unknown...

Herbal medicines have been widely used all over the world since ancient times and have been recognized by physicians and patients for their better therapeutic value as they have fewer adverse effects as compared with modern medicines. However, phytotherapeutics needs a scientific approach to deliver the components in a sustained manner to increase patient compliance and avoid repeated administration. This can be achieved by designing novel drug delivery systems for herbal constituents. Novel drug delivery systems not only reduce the repeated administration to overcome non-compliance, but also help to increase the therapeutic value by reducing toxicity and increasing the bioavailability, and so on...
