Course Overview

Join herbalists Ash Sierra of Ritual Botanica and Erika Galentin of Sovereignty Herbs for an 8-week online interactive intensive exploring planetary archetypes within the plant kingdom. Come learn how the framework of medical astrology can help us to conceptualize the actions, indications, and energetics of medicinal herbs and botanical aromas and their impacts on body, psyche, and spirit. To interactively demonstrate these concepts from the cosmos, each participant will receive a course kit which contains herbs and botanical aromas which will be incorporated into each class in the form of group tea tastings and guided meditations. Each kit will also contain seeds for some of the medicinal plants we study so you can grow them in your own gardens. All classes (8 total) will be recorded so participants who are unable to make the live classes will still be able to participate.

Calling upon the planetary archetypes…

Calling upon planetary and zodiac archetypes to illuminate the healing qualities of plants is a practice that spans generations and cultures. In the Western tradition, it is an aspect of the larger approach to healing known as Medical Astrology. Each planet harnesses its own characteristics; as depicted by the adage ‘As Above, So Below’, these characteristics also manifest in the human body as well as in the plant kingdom. In this regard, studying the planetary associations of healing herbs and aromas can provide an excellent framework for navigating the complexities of choosing which herbal and aromatic tools to use in support of body, psyche, & spirit. Each week, beginning with an introduction to the framework of Medical Astrology, we will taking a deep dive into the traditional seven planets (those that are visible in the night sky with the naked eye) and their herbal and aromatic counterparts here on Earth. To accompany and embody the concepts we will be exploring, each class will also contain group tea tastings and aromatic meditations using high quality herbs and aromas from your course kit!

Included in this course:

Each participant will receive:

~ a PLANTS + PLANETS kit which contains herbs, aromas, and seeds of plants that correspond to each planet we will be studying for each class. These kits contain hand-crafted items from Ritual Botanica and Sovereignty Herbs.

~ Weekly 2-hour classes for 8 weeks which cover both theory and framework for exploring planetary archetypes as well as interaction in the form of group tea tastings and guided meditations with aromas. Interacting with the herbs and aromas with the group will demonstrate and assist with embodiment of each planetary archetype.

~ Access to all class recordings which can be downloaded for lifelong access (you will have access to recordings to download for 90 days after the last day of the intensive).

~ Extensive handouts for future reference including a list of resources for future study.
