    WHAT IS VITALISM

    In this ancient tradition, each plant is a unique expression of life, a repository of wisdom that has been shaped over millennia. To engage with herbs in a vitalistic way is to enter into a
    relationship—not a transaction, but a communion—with the plant, where healing is not
    simply a matter of chemistry but of spirit, energy and intelligence.
