Dao Chi San is a 4-ingredient Chinese Medicine formula with Akebia Stems (Mu Tong) as a principal ingredient.
Invented in 1119 AD, it belongs to the category of formulas that clear Heat from the Organs. Its main actions are: 1) clears the Heart and 2) promotes urination.
In Chinese Medicine health conditions are thought to arise due to "disharmonies" in the body as a system. These disharmonies are called "patterns" and the very purpose of herbal formulas is to fight them in order to restore the body's harmony.
In this case Dao Chi San is used by TCM practitioners to fight patterns like Full-Heat in the Small Intestine. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as stomatitis, oral thrush or night terrors for instance.
On this page, after a detailed description of each of the four ingredients in Dao Chi San, we review the patterns and conditions that Dao Chi San helps treat.
Mu Tong is a king ingredient in Dao Chi San. Like the name indicates, it means it has more power than other ingredients in the formula.
Part used: Dried stem
Category: Herbs that drain Dampness
Di Huang is a deputy ingredient in Dao Chi San. This means it helps the king ingredient(s) treat the main pattern or it serves to treat a coexisting pattern.
Part used: Prepared dried root tuber
Category: Herbs that cool the Blood
Dan Zhu Ye is an assistant ingredient in Dao Chi San. This means that it either serves to reinforces the effect of other ingredients or it moderates their toxicity.
Part used: Dried stem and leaf
In general Dan Zhu Ye's main actions are as follows: "Clears Heat and aids thirst. Aids urination and drains Damp-Heat."
Gan Cao is an envoy ingredient in Dao Chi San. This means that it directs the formula towards certain area of the body and/or harmonizes the actions of other ingredients.
Part used: Dried root and rhizome
Category: Tonic herbs for Qi Deficiency
Gan Cao treats painful urinary dribbling, in addition to resolving toxicity and harmonizing the actions of the other herbs in the formula.
It's important to remember that herbal formulas are meant to treat patterns, not "diseases" as understood in Western Medicine. According to Chinese Medicine patterns, which are disruptions to the body as a system, are the underlying root cause for diseases and conditions.
As such Dao Chi San is mostly used to treat the pattern "Full-Heat in the Small Intestine" which we describe below.
But before we delve into Full-Heat in the Small Intestine here is an overview of the Western conditions it is commonly associated with:
Again it wouldn't be correct to say "Dao Chi San treats stomatitis" for instance. Rather, Dao Chi San is used to treat Full-Heat in the Small Intestine, which is sometimes the root cause behind stomatitis.
Now let's look at Full-Heat in the Small Intestine, a pattern that TCM practitioners commonly treat with Dao Chi San.
