Pharmacognosy is a science, which study natural products as a source of new drug leads and effective drug development. Rational and economic search for novel lead structures could maximize the speed of drug discovery by using powerful high technology methods. Reverse pharmacognosy, a complementary to pharmacognosy, couples the high throughput screening (HTS), virtual screening and databases along with the knowledge of traditional medicines. These strategies lead to identification of numerous in vitro active and selective hits enhancing the speed of drug discovery from natural sources...

On-line high performance liquid chromatography (HPLC) coupled with three biochemical detection (BCD) methods were applied to evaluate bioactive components in Danshen injection. On-line HPLC-photo-diode array (PDA)-fluorescence detection (FL) based on the fluorogenic substrate 7-acetoxy-1-methyl quinolinium iodide (AMQI), was built to search acetylcholinesterase (AChE) inhibitors in Danshen injection. On-line HPLC coupled with 1,1-Diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-Azinobis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) radical scavenging assay was developed to screen antioxidants...

Aromatherapy is a Practical or Complementary Health Therapy that uses volatile concentrates extracted from plants called essential oils, in order to improve physical, mental and emotional well-being. Aromatherapy has been practiced historically and worldwide by nurses and, as in Brazil is supported by the Federal Nursing Council, it is relevant to discuss this practice in the context of Nursing through Theories of Nursing. This study of theoretical reflection, exploratory and descriptive, aims to discuss the pharmacognosy of essential oils, the historical trajectory of Aromatherapy in Nursing and the conceptions to support Aromatherapy in light of eight Nursing Theorists (Florence Nightingale, Myra Levine, Hildegard Peplau, Martha Rogers, Callista Roy, Wanda Horta, Jean Watson and Katharine Kolcaba), contributing to its inclusion as a nursing care practice...

The chapter deals with tools and techniques employed in pharmacognosy. Pharmacognostic evaluation helps to screen the commercial varieties, substitutes, adulterants and any other quality control of the drugs. It is a simple and reliable tool, helps to obtain information about biochemical and physical properties of crude drug. Methods such as macroscopic and microscopic analysis, maceration, histochemical colour reaction, photomicrography, organoleptic character of plant powder and extracts, fluorescence analysis of plant powder with different chemical reagents, determination of pH of plant powder, water solubility index (WSI) and water absorption index (WAI) and acid value are discussed...

Kampo-medicine has become popular in Japanese medical practice combined with western medicine. For example, Daikenchu-To for intestinal obstruction after surgical operation, Shakuyakukanzo-To and Goshajinki-Gan for anti-cancer agents-induced neuropathy, and Yokkan-San for behavioral psychological symptoms of dementia are alternatively used in addition to conventional treatments in Japan. However, combined use of Kampo-medicine and western medicine may cause unexpected adverse events including undesirable drug-drug interactions because Kampo-medicine was not originally developed to be used with western medicine...

An approach to educating our pharmaceutical students about Kampo medicine in the six-year system of undergraduate pharmacy education at Kyoto Pharmaceutical University is introduced, including the author's opinions. Curriculum revisions have been made in our university for students entering after 2012. In teaching Kampo medicine at present, a medical doctor and an on-site pharmacist share information difficult to give in a lecture with the teaching staff in my laboratory. For example, before the curriculum revision, we conferred with a pharmacist and a doctor in the course "Kampo Medicine A, B" for 4th year students, in which students were presented a basic knowledge of Kampo medicine, the application of important Kampo medicines, combinations of crude drugs, etc...

In the Faculty of Pharmaceutical Sciences at Toho University, Kampo education commenced 40 years ago through a course titeled "Kampo", which has since been renamed as "Kampo Pharmacology". The current university curriculum offers courses in subjects such as Pharmacognosy and Practical Pharmacognosy for sophomores, Kampo Pharmacology for juniors, and Clinical Kampo Medicine for seniors. Kampo Pharmacology is a subject that bridges "Pharmacognosy" to "Clinical Kampo Medicine". The functions of the crude drugs included in Kampo prescriptions are explained both in terms of efficacy from the perspective of Kampo and by contemporary evidence...

BACKGROUND: Savīryatā-avadhi (shelf life) of different Ayurvedic dosage forms is described in Śārṅgadharasaṃhitā. Though the concepts have a strong background, we seek to re-evaluate the age old concepts by following current norms. An attempt has been made in the present study to evaluate shelf-life of Kaṃsaharītakī avaleha and its granules. MATERIALS AND METHODS: Raw materials were procured from Pharmacy, Gujarat Ayurved University, Jamnagar and utilized after proper authentication in pharmacognosy lab...

The mullein (Verbascum phlomoides L., V thapsus L., V. thapsiforme Schrad., V. speciosum L.) is a medicinal herb known and used for a long time, especially in traditional Turkish medicine. The aims of our study were to identify the species and study the plant's major active substances both qualitatively and quantitatively, comparing it to data found in scientific literature. The plants were identified as probable hybrids of V. phlomoides and V. thapsiforme. Microscopic analysis of the flowers showed no major difference between the specimens...

A majority of Africans rely on traditional medicine as the primary form of health care. Yet most traditional medicine products have a short shelf life, especially for water-based formulations such as macerations, infusions and decoctions. Indeed, many of these water extracts become unfit for human consumption after five to seven days of conservation either because of the degradation or toxicity of active components, and/or the growth of pathogenic organisms. The purpose of this study was to describe and apply a new approach for the development of an improved traditional medicine (ITM) that is cheap, very efficient, not toxic, and easy to produce, and that can be conserved for a longer time without a significant loss of activity...

The "Colóquios dos simples e drogas he cousas medicinais de Índia" (Conversations on the simples, drugs and medicinal substances of India) (1563) of Garcia da Orta is a botanical and pharmacognosy book. The author is a Portuguese physician who studied in the Spanish universities and practiced medicine mainly in India. He studies in short chapters presented in the form of dialogues about sixty simples. Sources to which he refers are indicative of a "classical" training, but also the mark of a curious and open mind to different cultures...

Herbal medicines have recently been recognized as the second most common cause of drug-induced liver injury (DILI) in the United States. However, reliable methods to identify the DILI causality of some herbs, such as Heshouwu (dried root of Polygonum multiflorum), remain lacking. In this study, a total of 12 307 inpatients with liver dysfunction and 147 literature-reported cases of Heshouwu DILI were screened. A general algorithm indicated that only 22.5% (9/40) and 30.6% (45/147) of all hospitalization and literature case reports, respectively, demonstrate the high probability of DILI causality of Heshouwu...
