Clinical herbalism and aromatherapy should necessarily be based on a sound understanding of both botanical pharmacology and modern pathophysiology. This goes without saying.

There are, however, insights to be gained from exploring the subtle, esoteric dimension of plant medicine and their associated aromatics— as doing so in a non-essentialist way can arguably deepen our insight into the psychological benefits of essential oils. It is an aspect of aromatherapy that finds its historical antecedents in the diverse use of natural plant fragrance in shamanistic practice and manifold spiritual traditions.

In this series of ten 3-hour illustrated webinar presentations, Gabriel Mojay and Shellie Enteen share their mutual long-standing study and practice of the Psychological and Medical Astrology of aromatic plants and essential oils. The course will cover the fascinating range of topics that together form the basis of an ancient intuitive discipline.

Participation on the course requires no prior knowledge of astrology, though previous training in aromatherapy or herbal medicine is required.

Gabriel and Shellie will introduce the fundamentals of Traditional Astrology with special reference to both psychological and physical health. They will discuss how the constitutional and emotional causes of disease are reflected ‘synchronistically’ in one’s individual Astrological Birth Chart – and in particular by the energetic tensions arising from the dynamic aspects between the different planets and the corresponding psychological drives that constitute the core of one’s Birth Chart.

As part of the course, each participant will be given the option of submitting the necessary information (date of birth; time of birth; place of birth) for their Astrological Birth Chart to be prepared in advance of the course, according to the facilitators’ standards, in order to ensure each student’s wholly accurate reference point of study.

The course will encompass a critical look at the extant literary and ethnobotanical symbolism of various aromatic plants — and how their age-old mythological and planetary associations illuminate the therapeutic nature of their related herbs and essential oils.

What’s more, as we learn to interpret the individual Astrological Birth Chart in terms of health and energetic disharmony, we will at the same time examine the psychological benefits of relevant essential oils – including their most important evidence-based neuro-pharmacological activities; for example, the serotonergic activity of Lavandula angustifolia and how key neurotransmitters such serotonin can be seen in the symbolic light of the fact that Mercury owns the herb, and carries its effects very potently. (Nicholas Cupleper, 1794)

Please note that the course will not include tuition in manual chart construction, as there is a wide choice of software that performs this function efficiently. Neither will we discuss in depth astrology as a predictive tool. The emphasis, rather, will be on interpreting the Birth Chart from a psychological and therapeutic viewpoint — and as a symbolic mirror of character and soul.

The goal of the course is to train participants to use the Astrological Birth Chart to shed light on various issues relevant to individual well-being. In addition, it will provide further insight into the psycho-spiritual benefits of a range of important aromatic plants and essential oils — and how their selection and blending can be enhanced by sensitive use of the Birth Chart as a tool of intuitive ‘diagnosis’.
