Main objectives of this WHO monographs is to provide a model that
will support countries in developing their own national or regional monographs
on medicinal plants or national formularies on herbal medicines. It contains the
scientific information on the safety, efficacy and quality control/quality
assurance of widely used medicinal plants.
This lecture note focus on the
role of plants in this world and their interaction with other plants, insects,
herbivores, pathogens, fungi and humans. These interactions are based on the
plant primary metabolism with its cheap supply of sugar for bribes as well as on
secondary metabolites for bribes, defense and repulsion.
Insectivorous Plants is a book by British
naturalist and evolutionary theory pioneer Charles Darwin. The book chronicles
Darwin's experiments with various carnivorous plants, in which he carefully
studied their feeding mechanisms. Darwin tried several methods to stimulate the
plants into activating their trap mechanisms, including feeding them meat and
glass, blowing on them and prodding them with hair.
This book is designed to furnish classes
in our schools and colleges with a suitable text book of Structural and
Physiological Botany, as well as private students with a convenient introductory
manual, adapted to the present condition of the science.
This book is
the result of several years 1 experience of the authors with the Intermediate
classes. A lot of time is usually wasted in giving instructions and notes to the
students as to the procedure of the day's work. The authors feel that this
humble attempt at systematizing the practical work of Intermediate classes, will
go a long way to remove this difficulty.
This structural work
has been supplemented by so much classification as will serve to make clear the
relationships of different groups, and the principles upon which the
classification is based, as well as enable the student to recognize the commoner
types of the different groups as they are met with. The aim of this book is not,
however, merely the identification of plants.
This book covers the following topics: Plant Societies, The Plant Body, Seeds and Germination, The Root — The Forms of
Roots, Function and Structure, The Stem — Kinds and Forms, Pruning and General
Structure, Leaves: Form, Position, Structure, Anatomy and Function or Work,
one knows when herbs of medicinal value were first used and few care to even
venture a guess. In all probability, certain unknown early plants which produced
a feeling of well-being were recognized and ingested regularly by the primates
who preceded man. After the emergence of man, in the early dawn of time, there
followed thousands of centuries of gastronomical experimentation by this
strange, upright being, during which time he learned to select from available
foods those which were best suited for his system
