Tree Spirit Medicine with Monika Ghent

Medicine from Willow: Transforming confusion into clarity; knowing your path and purpose.

Each of us has an inherent purpose and path that we are meant to live. To not do so is the cause of much of our confusion and suffering. The yearning to live our vision and truth may be postponed, avoided or stifled, but it does not and will not go away. It must be acknowledged and expressed for us to live a joyful, fulfilling life.

Willow medicine transforms confusion into clarity so that we may come to know who we are and the path we need to walk. In this experiential workshop participants will have the opportunity to enter into the dream of Willow and receive it's medicine.

This workshop is for anyone who feels the yearning in their heart to know themselves more fully regardless of philosophy or faith, or whether they are a ‘plant person’ or not.

Date:  10 am to 5 pm.

The Science and Art of Herbalism Home Study Course

Last Tuesday of each month (Sept thru May) 7:00 – 8:30 pm at Dogwood & Brambles Farm.

The Science & Art of Herbalism Home Study Course emphasizes self-care, home health, and self-reliance. More than any one system of healing, herbalism offers a low cost alternative to health care. This self-empowering joyful course is recognized as one of the best home study courses available on this subject. Written by Rosemary Gladstar (40 years of herbal wisdom) and facilitated by Penelope Beaudrow (20 + years of herbal wisdom).

The Science & Art of Herbalism guides you into the very heart of herbalism. It instills in the student both the necessary skills to practice this ancient healing art as well as a profound understanding of the spirit and essence of herbalism. Penny is your instructor throughout this course, bringing a wealth of herbal knowledge, excellent training skills, and a passionate love of herbs to this course. Written in an inspiring and joyful manner, The Science & Art of Herbalism  was designed specifically for students requesting a systematic, in-depth study of herbs but who were unable to attend full time residential herb programs. It contains a depth of knowledge and a lively student/teacher interaction seldom found in home study courses.

Though it thoroughly instills in the student the practical skills necessary to practice herbal home health care, it doesn’t ignore the rich spirit and essence of herbalism. The heart of this course is the development of a deep personal relationship with the plant world.

Course Includes:

  • Ten lessons in a beautiful, specially designed course binder
  • Correction of all homework
  • Certificate upon completion

Each lesson will have herbs that must be purchased for study purposes (materia medica).  The Ginkgo Tree will prepare small quantities to keep costs down for students.
