Guido Masé RH (AHG) is a clinical herbalist, herbal educator, and garden steward specializing in holistic Western herbalism (though his approach is eclectic and draws upon many influences). He spent his childhood in the Italian central Alps and in a Renaissance town called Ferrara. After traveling around the United States, he settled in Vermont where he has been living since 1996.

He is founder, faculty member, and clinical supervisor at the Vermont Center for Integrative Herbalism, a 501(c)(3) nonprofit herbal medicine clinic and school that provides comprehensive services focused on whole plants and whole foods. He serves as chief herbalist for the Urban Moonshine Natural Products Company, where he works on research, development, and quality control for an all-organic whole-plant tincture line and offers herbal medicine education. He is a founding member of the Burlington Herb Clinic, a worker-owned herbalist cooperative where he houses his clinical practice. He participates in herbal education at the University of Vermont, and is the author of The Wild Medicine Solution: Healing with Aromatic, Bitter and Tonic Plants (Healing Arts Press, 2013) and DIY Bitters: Reviving the Forgotten Flavor (Fair Winds Press, 2016).

Guido's style focuses on conveying the interconnections within the human organism and between the organism and its surrounding ecology. He has a constant eye on the amazing beauty such study reveals. Such a relational awareness provides meaning and context, critical elements to understanding and healing.

At home, he spends time with his wife Anne and daughter Uli. He enjoys cooking and eating with family and friends, writing on topics in herbal medicine and human physiology, playing music, and experimenting with distillates and novel herbal formulae. Time alone is usually spent running on road and trail (often in the very early morning).

Guido works clinically and teaches as a professional member of the American Herbalists Guild, and is actively involved with United Plant Savers and the American Botanical Council.
