Chinese herbal formulas are an integral part of Chinese medicine and have been used for centuries to promote health and treat various ailments, known as patterns. The formulas consist of a combination of herbs carefully selected and combined to achieve specific therapeutic effects. Herbal formulas are crafted blend of substances designed to function synergistically. This synergy applies to herb pairs and herb combinations consisting of up to over a dozen substances. The blends serve many purposes. Herbal pairs can serve to balance or enhance to strengthen the effects, counterbalance an undesirable property, or harmonize herbs in the formula.
Additionally, specific therapeutic strategies and methods underlie the formulation and application of herbal combinations. One of the fundamental principles in formulating Chinese herbs is the concept of herb pairs. Another fundamental principle in formulating herbs is to enhance a targeted area and or affect.

Herb pairs in Chinese herbal formulas refer to the strategic combination of two herbs that work synergistically to enhance their therapeutic effects. These pairs are designed to balance each other’s properties, increase potency, and minimize potential side effects. For example, one herb may target a specific symptom or organ, while the other herb can harmonize or enhance its action.
Herb Formula Assembly
When assembling a Chinese herbal formula, several factors are taken into consideration. One consideration is herbal pairs and herbal supports. To enhance a targeted area or affect, herbs are assembled strategically under 4 categories. The categories are chief, deputy, assistant, and envoy.
Chief. The chief herb(s) is the main ingredient in the formula that is directed toward the principal pattern of pathology. The chief herb(s) is indispensable as it has the greatest effect for treating the pattern.
Deputy. The deputy herb(s) aids the chief herb in treating the principal pattern or pathology and serves as the main ingredient to treat any coexisting patterns or comorbidities.
Assistant. The assistant herb(s) reinforces the effect of both the chief and deputy herbs, and directly influences a less important aspect of the target pattern or comorbidities. The assistant herbs also moderate or eliminate potential harsh nature of other ingredients to reduce toxicity or side effects of other herbs in the formula.
Envoy. The envoy herb(s) guide the actions of the chief ingredients to specific target areas within the body and focuses the action of the formula on a certain channel or area of the body. The envoy also harmonizes and integrates the actions of the other ingredients in the formula.
Additionally, the directions in which the herbs are combined in a formula are crucial. The order and proportion of each herb are carefully determined to maximize their synergy and minimize potential interactions or side effects. The precise assembly of these herbs aims to create a harmonious and effective blend that addresses the underlying imbalances causing the symptoms.
By combining herbs strategically, Chinese herbal formulas offer a holistic approach to healing, aiming to restore balance and promote well-being in the body. These formulas are tailored to individual needs and have been widely used to treat a broad range of health conditions in TCM.
