During the past 50 years there have been tremendous advances in chemical and biological techniques of analysis that have transformed research in pharmacognosy. The PSE has regularly held symposia of relevance to pharmacognosy and some of these are briefly reviewed in the area of natural products from higher plants. These symposia have charted the developments that link pharmacognosy with phytochemistry and illustrate the application of increasingly more sophisticated analytical techniques to the discovery of biologically active compounds. Plants have yielded clinical drugs, either as natural product molecules, or as synthetic modifications, particularly for chemotherapeutic treatment of cancer and malaria. Aspects of biotechnology, traditional medicines and herbal medicinal products are briefly discussed.

    • "This has led to the discovery of new drugs along with new applications (Table 1). These bioactive molecules are used as therapeutic agents, starting materials and new reagents for molecular biology research (Balunas, 2005; Lam, 2007; Mishra, 2008 and Phillipson, 2007). "

    ABSTRACT: Plants have been well documented for their medicinal uses for thousands of years and traditional medicines are still a major part of habitual treatments of different maladies in different parts of the world. In recent years, there has been growing interest in alternative therapies and the therapeutic use of natural products, especially those derived from plants. Plants are considered as one of the main sources of biologically active materials. Phytochemical screening of medicinal plants has contributed a great deal for the discovery of new drugs. A number of medicinal plants have been subjected to detailed chemical investigations and this has led to the isolation of pure bioactive molecules which have been pharmacologically evaluated. As a result, new drugs have been discovered, along with new applications.

    • "These elements are selected examples that show how zoology and pharmacology are linked and how important describing the interactions between both fields could contribute in the development of the two fields both at the experimental and at the theoretical level. Furthermore, combining data provided by the related fields such as pharmacognosy (Ghanemi and Boubertakh, 2014) especially by studying the properties of chemical (Ghanemi, 2014a,e) or natural products (Boubertakh et al., 2013; Phillipson, 2007) on cells, biochemistry (Ghanemi, 2013b) and cellular biology will surely be very beneficial to a better mapping of the bridges between zoology and pharmacology toward deeper understanding and further advances.

    • "Gemmotherapy is a therapeutic method belonging to the field of Biotherapy, which, based on the analogical–biochemical principles of biological drainage, uses hydroglyceroalcoholic solutions of macerated fresh plant extracts in the first decimal dilution for therapeutic purposes [1] [6]. These extracts consist of meristematic tissues, such as buds, sprouts, young stems, rootlets, catkins, the inner root cortex, the young branch cortex, sap, seeds, and other meris‐ tematic plant tissues in the growth phase [10]. To express the concept at a taxonomic level, it would be more correct to describe the method as " meristemotherapy, " since the used plant tissues are of meristematic origin. "
