4 Hierarchy of Herbs in a Formula
1. Chief (jun yao, 君药): The must have ingredient and the main active ingredient against an ailment
2. Deputy (chen yao, 臣 药): The ingredient that supports the chief ingredient or is a main ingredient targeting a coexisting disease.
3. Minister (Zuo Yao, 佐药): The ingredient that 1) reinforces the effect of the chief or deputy ingredient, or treats a less crucial part of the disease. 2) moderates the toxicity of the chief or deputy by having an opposing effect of the chief ingredient.
4. Guide (Shi Yao, 使药): 1) Focuses the action of the formula on a specific channel or body part. 2) Harmonizes and integrates the actions of ingredients.

- Chief ingredient is constant but all or most of other ingredients are changed and the action of the formula is changed.

Forms and Preparations
Decoctions (tang ji, 汤剂): All ingredients are boiled with water, wine or both. The broth is strained into a cup and drank by the patient. Advantages are the quick absorption and immediate relief. It's easy to adapt the formula to patient needs. Disadvantages are the bitter taste, the time-consuming preparation, the expense, and hard to prepare as exactly prescribed. The effectiveness of Decoctions depends on proper water, equipment (stoneware, ceramic, or stainless steel), amount of water (half inch above herbs or 250ml to 30g herbs), heat (high or low), and time/frequency (decoct twice or cook longer).
Powder (san ji, 散剂): Ingredients are ground into powder. The powder form can be blown into the nose or throat, or put into a tea bag and steeped as tea. Advantages are the lower cost, the ability for longer storage, quicker preparation and can easily adjust dosage size by varying the amount of powder.
Pills (wan zi, 丸子): Pills are absorbed slowly and over a long period of time. It's easier to sore and less expensive. This form is usally used for chronic disorders. It's also used for ingredients that should not be boiled. Most pills are made with water, honey, or other coagulants.
Soft Extracts (gao ji):
- Gao Yao - Ingredients are cooked with water or vegetable oil until dissolved and congealed. When mixture is combined with with beeswax, it forms a plaster.
