Botanical Dimensions is looking forward to hosting herbalist Madalyn Berg of The Community Medicine Cabinet who will be teaching us how to make fire cider on Tuesday, January 29 at 7pm. Learn a great shareable recipe for a delicious tonic that will carry you through the end of cold season and towards wellness in 2019. A flexible recipe that uses spicy and savory roots and herbs, with honey and vinegar. This tasty and potent protective recipe has been handed down for many years. Fire cider is an example of folk knowledge that is available to everyone. In this class, make enough to take home now to fend off the chills of March, and then you can make enough to share when winter colds start to come around later in the year.

What is coming in 2018 ~

by Botanical Dimensions on 11/21/2017

We have some great learning opportunities coming up in 2018. Kathleen Harrison and guest teachers will offer all-day and half-day classes on a variety of topics, beginning in March.

  • 4-part Global Ethnobotany with a Local Focus, taught by Kathleen Harrison over 4 months, with nature walks.
  • The Art of Seeing, Drawing & Painting Plants: a weekend with artist Donna Torres and Kathleen Harrison
  • Who is Tobacco? An all-day workshop that examines a variety of spiritual and protective uses of this complex plant teacher. With seeds and samples for cultivating your own healthy ally. (This plant is not all shadow.)
  • Plants and Cultures of the Motherpeace Tarot, taught by this classic deck’s co-creator and artist, Karen Vogel.
  • Sweeping the Mountain of Nerves – Universal techniques in cleansing, grounding and protecting yourself or others, with Kathleen.

We’d like to see the Ethnobotany Festival & Symposium happen again next harvest season, but we are seeking a donor to underwrite the event budget. The first festival, in 2016, was spectacular, so be sure to not miss the next one, whenever that may be. All ages welcome.   Come visit the festival, our library, and the beautiful redwood forests of West Sonoma County. Then swing by the spectacular Sonoma Coast, while you’re so near it. We will let you all know when we have gathered enough resources to then host the expert teachers who will represent the many facets of ethnobotany. If you can  help now, please donate! Thank you.

Native plants provide food and basket material, in the skilled hands of native people.
