Craig Mitchell on the use of classic formulas
How is it that you ended up in Taiwan to pursue your study of language and medicine?
It had to do with Andy Ellis, I met him when still in school and through our association started to study the Chinese language. It is difficult to study Chinese in the US. Andy suggested that as I did not have family or other commitments I might consider going to Asia, as being immersed in a Chinese speaking environment would be good for my acquisition of Chinese.
When I first arrived in Taiwan I spent time doing medicine in the clinics of some people that Andy knew. It was after being there for a year that I met Nigel and really got into the language.

Many people think that the formulas and theory found in the Shang Han Lun are only applicable to cold climates. Taiwan can be quite hot and humid. How did you see the doctors there applying the “classic formulas” there?
I got pretty sick after getting to Taiwan. It was primarily a digestive system problem. At the time I had no idea what was going on, and felt so bad that I almost went home. But, it turned out to be a Ban Xia Xie Xin Tang presentation. It was a slam-dunk diagnosis for the doc that I saw. The formula worked very quickly, as I took the herbs and felt magically better. My condition was not the result of the classic exterior pattern that had been purged, as is described in the Shang Han Lun. It was just disharmony between self and environment. These classic formulas have a broader scope of utility than we learn in school. The Taiwanese docs used them in all kinds of creative ways. Problems being caused only by cold is not true in clinical reality.
You have to try and understand the patho-mechanism. Understand not just symptoms, but what do those symptoms represent. What kind of picture is being painted? One thing I’ve found helpful, it is purely my own mental noodling, is to think of the lines of the Shang Han Lun as kind of a clinical notebook. There is more utility to it when you think of the lines illustrating a certain situation and understand that the way it is described is not the only way it can happen. It is an image of that kind of patient.
I’ve found this at times when reading case studies of the Masters. You read their cases and the patient does not have the usual symptoms, but they have the patho-mechamism; based on that they prescribe.

It was you who laid that first copy of 10 Key Formulas Families in Chinese Medicine on me in Beijing in 2002. How did you come across that book in the first place? When you are looking for resources in Chinese, what do you look for?
Sometimes I look for a specific author I like, for example Liu Du-Zhou. I am interested in his perspective, so I read whatever he writes.
The other thing is that sometimes there are specific books based on content. If there is a Shang Han Lun or Jin Gui book that I have not seen before, I will give it a look. I also like case studies, so I browse those and I like the jing fang books, where there are cases that trace a case to a line of the text.
I also enjoy the more classic works. Even though the older authors can be more difficult to read, they are interesting. I like to read texts from 500 years ago that have case studies and see how their treatments compare with modern methods.
One of the best ways to visit bookstores is to go with one your Chinese teachers and see what they like and follow their suggestions!

I’ve heard a number of discussions about using classic formulas to “unstuck” a pathogen. In fact, sometimes knotty and intractable problems can be due to this issue. Can you give us some insight into knowing when we are dealing a stuck pathogen? And tell us a bit about how pathogens get stuck? How about a case to illustrate the point?
For me, a key indicator that I’m dealing with this situation is when someone describes a situation where in a broad sense they can tell you when the problem started. They say something like “I never used to get headaches, but last year in the spring it seems things are different, and now…”
If they articulate that kind of progression it is a good indication that something got stuck. It does not need to be a traumatic event. They may not always remember right away what was the triggering incident, sometimes later they remember something happened.
Let me give you an example; this is a case at the very beginning of this kind of a process. I had a student a few years ago who had gone out and eaten a heavy meal that included ice cream. It was unusual for her to eat in this way. She felt bad after that and got constipated. It felt like food stagnation, so we tried Preserve Harmony Pill (bâo hé wán) and those kinds of formulas, nothing worked. When I took a further at her one of the interesting things was she had only mild discomfort in abdomen. I gave her Frigid Extremities Decoction (sì nì täng) with Cannabis Semen (huô má rén), which cleared the problem right up with one bag of herbs. This illustrates that some cold got lodged in the abdomen, causing damage to the yang qi, which in turn reduced peristalsis. Warming the yang to dispel cold did the trick.

For many of us, it is quite daunting to approach studying the Shang Han Lun. Can you give us some advice on getting started? How to approach this text in a way that will help us deepen our practices?
A couple of key points. First, don’t ignore the source text. It may be confusing and daunting, but if you have some of this in your head, it will be useful in the clinic when you see patients. As you are working you can ask yourself “does this line match this patient?” If the material is in your head, you are more likely to see it.
Concerning the use of formulas, it is best to use them with minimal modification until you understand how they work. That way you can tell if you if are right or not.
Finally, I want to again point out that it is essential to know what the underlying patho-mechanism is. This helps you to understand the patient and the course of their illness.
