This book presents the healing plants from A to Z. The most important vegetal and animal extracts are introduced whose highly remedial protective substances are of major importance, both in their pharmaceutical application and in the field of food supplements. The attention which natural sciences pay to so-called phytochemistry and vegetal chemicals is indicative of the tremendous significance of the healing power of plants, which due to their specific compositions and structures contain an outstanding chemically effective potential. The list includes indigenous medicinal plants such as bearberry, fennel seeds and parsley, as well as vegetal remedies of other folk medicines, e.g. Asian ginseng root, African yohimbine bark or Peruvian cats claw creeper. Special focus will be placed on the following questions: What ingredients are contained in these plants? What is their efficacy?German author Anne Simons was born in 1956. She studied English and French languages and literature in Münster and Munich (Germany) as well as in Lille (France). She has worked as a teacher and a translator of fiction and non-fiction books, studied natural healing methods and has written various books, some of which have become bestsellers. Her books on OPCs (Gesund länger leben durch OPC with Alexander Rucker and Das OPC-Arbeitsbuch) have made her well known. These and innumerable lectures in Germany, Austria and Switzerland on OPCs have made her popular in the German speaking parts of Europe. Anne Simons not only sifted through the vast amounts of scientific literature on OPCs that mainly existed in French and English, but she also presented it to the German speaking reader in a way so that everybody can understand this complex topic. She met Professor Dr. Masquelier, who discovered and explored OPCs, personally, and through many encounters, talks and letters the two developed a sincere friendship. Anne Simons thus had the rare opportunity to get first-hand knowledge on the extremely fascinating issue of OPCs.Anne Simons works on OPCs (books, e-books and booklets) have been published by MayaMedia and many can also be purchased in English, French, Italian, Spanish and Turkish.
