TCM Materia Medica
Within Traditional Chinese Medicine, herbs are divided into many categorizations which help to ensure they are used effectively. Below you will find herbs categorized by the meridians, or channels, that the herbs are thought to influence. When preparing formulas for a given condition you may use herbs that either effect a particular meridian or organ directly or herbs that will help lead the properties of other herbs into a particular channel.
For example, you may want an herbal formula that cools lung heat for a cough. You can use herbs that are directly cooling on the lungs or a combination of herbs that are cooling and have a strong influence on leading that property of the herbs to the lungs.
You may also use herbs to protect a certain channel or organ system from side effects of stronger herbs that you are using to treat a particular condition.
