Join us on a transformative three-day journey into the realms of Botanical Extracts, viewing them through the unique perspectives of both science and alchemy. Beyond being a classroom experience, this course is a deep dive into self-discovery, connecting with the plant world, and the integration of that knowledge into building our precious communities. While welcoming the power of the invisible realms of alchemy, this approach integrates fundamental botanical extraction knowledge with an emphasis on practical applications in topicals and cosmetics. 

Alice, a master in the art of botanical extractions, will also teach how to sustainably harvest the plants, the correspondence in the Biodynamic calendar as well as how to extract specific molecules (each solvent corresponding to a signature quality in a plant) for specific healing usages. These botanical extracts are a perfect base for making quality medicinal and cosmetic products as well as skin condition topicals. Several topics such as resinoids, roots, leaves, seeds and flowers will be treated separately with their corresponding techniques.

A range of cosmetically prized plants will be presented; giving the students the opportunity to create their hands-on experience; making their customized botanical extracts themselves while being guided by their teacher.

This class is designed for:

  • Cosmetic, topical, medicine and perfume formulators.
  • Estheticians looking to develop their line of botanical treatments.
  • Plant lovers, farmers and gardeners that want to expand their practical knowledge and find ways to transform what they grow into tangible products.

    Introduction to the realm of Flower Extracts

    Alice's background as a perfumer and aromatherapist led her to a deep fascination for these incredible gems of color and scent.  She ongoingly extracted these magical expressions of nature’s gift during seventeen years of hands-on experience for taste, aromas, and medicine. Further down the road, she discovered their capacity to heal the emotional patterns and blockages in humans and animals with the use of flower essences and aromatherapy. 

    Flowers are the most ethereal expression of Nature, they are the beauty and the promises of a new seed, a new future. In the alchemical world, they are related to the sun, the ether, and are the Gemstones of the natural world. They are the expression of the lighter realm, the hidden world, and vulnerability. We will explore their place in the natural kingdom and eco-system, the spiritual world and the emotional impact on humans and animals.

    Attending Friday evening is optional but highly recommended. Our plan is to have a more informal gathering the first evening in the Biophilia gardens or at a local Petaluma restaurant, (an email will be sent a week before the class with details). We'll use the time for a welcome and introduction talk by Alice, go over the logistics, arrange carpools to the class venue, do some Q&A, etc. Plus enjoy a bite to eat and relax after your travels. This way we'll be able to dive right in the next morning. (We'll send address details once it is finalized).

    The class will start promptly at 10 am. Please arrive at the latest at 9:45 in order to finish registration, settle in and make yourself a cup of tea.

    This class was not only enlightening in the tangible world of plants and preparation but, in the metaphysical real as well and our connection between the two. I enjoy learning from Alice as she has a way of teaching that welcomes the knowledge into your being. It was so fulfilling learning the deep and rich traditions of cultures and their applications that have been handed down, and continue to transmogrify dimensions with plants and the elements.
