This work by Paul Sedir is based on the traditional occult knowledge of the use of plants, as taught by Paracelsus and other masters. Sedir analyses plants from the botanogenic point of view, which considers the influence of the stars on them, and according to the law of signatures (plant physiognomy). This knowledge allows us to pick up the plants at the right astrological moment, and also shows us how to use them to develop our integral health, on all levels. This work also deals in depth with unusual topics such as Paracelsus’ system for transplanting diseases from a person to a plant, the hermetic use of plants, preparation of philtres, palingenesis, and many other subjects. The Dictionary of Botany , included in the third part of the work, includes more than three hundred plants, with their astrological signatures and medicinal and magical characteristics. In addition to providing the vulgar name of each plant in English -including its variations in different countries- we have added its scientific name in Latin. This allows the plants to be identified without any doubt and also makes it easier for the reader to gather more information about any plant with a simple Internet search using its scientific name. This book also has an alphabetical index to locate the plants by their Latin name and an Esoteric Glossary to familiarise the reader with the terminology of the work.
