      Jessica Clark, Clinical Herbalist

      To book a session with Jessica, call 707.595.7895 or email

      Jessica Clark is a gardener and beekeeper with a passion for connecting people to plants. She has been working with and around plants since childhood, constantly fascinated by their diversity and inspired by their wisdom. Several years living off the grid, farming, and honing her herbal craft in a natural setting allowed her to connect deeply with nature. This connection to the Earth drives her work and her practice of helping educate people on the empowering force of herbal medicine in their daily lives. She studied holistic herbalism for 2 years at the California School of Herbal Studies in Forestville, CA, and previously as an apprentice in Donna D’terra's Yerba Women Herbal Apprenticeship in Willits, CA. Jessica enjoys cooking, making medicine, hiking, and working in the garden in her free time. She is also involved in a free mobile clinic project, Bay Herbalism, which provides access to natural health care to under-served populations.

      As a practitioner, Jessica trusts in the innate process of healing inherent in each person, cultivating this gift with her clients. Through the intake process, she investigates the root causes of the "dis-ease," and works with them to craft a plan for renewal. She believes that each person is not their set of discomforts, but a complex whole being comprised of body, mind, spirit, and soul having a unique experience. She recognizes that each symptom is part of a language which the body uses to try to communicate its needs. Actively tuning in to what the body is trying to say, she creates unique herbal formulas for clients, along with a road map of lifestyle adjustments, self care practices, personal reflections, and appropriate supplementation.

      Drawing upon Traditional Western Herbalism, the wisdom of the plants, constitutional theories from various traditions, the language of energetics, pulse and tongue analysis, modern science and her own intuition, Jessica meets clients where they are, providing attainable steps in their process of healing. She works with each person to create a realistic plan, aiding them in their own self-healing, allowing them to take charge of their personal health journey.
