Traditional Herbalist around the world view the body as a landscape and much like a skilled gardener offer herbs to either remove excess elements in the garden such as water or use herbs to add elements that are deficient such as minerals. The most basic language of this practice is found in the principals of yin and yang in Traditional Chinese Medicine (TCM). Although I do not practice TCM, I have found this elegant approach to understanding imbalances in the body/mind have taught me much about assessing a patient's health and offering the most appropriate herbs for their condition.
