Mastering the Yang Wei Mai: Essential Insights for Acupuncture Students Preparing for the NCCAOM Exam

Hello everyone,

Welcome back to "Study Acupuncture with Me." In this blog post, I'm excited to dive deeper into Episode 53, where we thoroughly explored the Yang Wei Mai (Yang Linking Vessel) and its three key clinical applications. For those gearing up for the NCCAOM exam, understanding this extraordinary vessel is crucial. Let's break down everything you need to know.


Introduction to the Yang Wei Mai

The Yang Wei Mai, also known as the Yang Linking Vessel, links all the yang channels in our body. Just like the other extraordinary vessels, the Yang Wei Mai has both an opening point and a coupled point. These points can be stimulated to activate the Yang Wei Mai.


Key Points of the Yang Wei Mai:

- Opening Point: Sanjiao 5

- Coupled Point: Gallbladder 41


Pathway of the Yang Wei Mai

Understanding the pathway of the Yang Wei Mai is essential for accurately diagnosing and treating clinical conditions. Here’s a step-by-step pathway guide:

- **Starts at**: UB 63

- **Moves to**: GB 35 (located on the side of the lower leg)

- **Traverses**: The outside of the thigh along the IT band to GB 29 (a favorite point for hip and IT band pain)

- **Ascends**: Side of the abdomen, beneath the armpit, and to the shoulder area


The shoulder area is where the Yang Wei Mai zigzags, interacting with multiple points from the San Jiao, Small Intestine, Large Intestine, and Gallbladder channels. Prominent shared points include:

- Sanjiao 13

- Sanjiao 15

- Small Intestine 10

- Large Intestine 14

- Gallbladder 21


Finally, the channel ascends the side of the neck, passes behind the ear, and finishes from GB 20 to Gallbladder 13.


Reference Materials:

Bear in mind that there may be slight variations in the pathway details between different references like Maciocia and Deadman. For instance, Deadman includes points such as Due 16 and Due 15, and Stomach 8, whereas Maciocia does not. However, this variation is generally not stressed in board exams, so focus on understanding the main pathway.


Clinical Applications of the Yang Wei Mai

1. Treating Intermittent Fevers

Intermittent fevers are characterized by a fever that spikes and then returns to normal. Later, the fever spikes again and normalizes in a cyclical manner. The Yang Wei Mai can effectively treat these intermittent fevers.


Additionally, the Yang Wei Mai can be used to treat alternating chills and fevers, which involve the fluctuation between fever and chills (e.g., hot one moment and cold the next).


KEY CONCEPT: The alternating chill and fever pattern is a hallmark of the Shaoyang stage in the Six Stages Theory. This stage represents a pathogenic factor stuck halfway between the interior and exterior.


2. Treating Pain on the Sides of the Body

The extensive pathway of the Yang Wei Mai along the side of the body makes it incredibly effective for treating conditions affecting this area. Here are some conditions to consider:

- IT band syndrome

- Osteoarthritis

- Degenerative diseases


In these cases, you can employ not only the shared points but also the opening (Sanjiao 5) and coupled (Gallbladder 41) points to alleviate side body pain.


3. Treating Ear Problems

The pathway of the Yang Wei Mai near the ear area enables it to treat ear-related issues effectively. This includes:

- Ringing in the ears (tinnitus)

- Deafness

- Ear pain and other ear-related disorders


Activation of the Yang Wei Mai can be accomplished through the opening and coupled points, or by stimulating any of the shared points along its pathway.


Professional Practices and Interdisciplinary Collaboration

In serving our patients' best interests, it's imperative to collaborate with other healthcare providers. Here are some best practices:

- **Referral to Specialists**: For complex cases (e.g., kidney-related pain on the sides of the body, severe ear issues), refer your patients to primary care physicians or specialists for a comprehensive evaluation.

- **Sharing Treatment Progress**: Keep other clinicians informed about the progress of your mutual patients. Type up a one-page summary detailing your evaluation findings, treatments administered, and any objective measures of progress. This can be shared with the patient for their primary care checkup.


Remember, as acupuncturists, we are part of the wider medical community. Clear communication and collaboration help ensure the best outcomes for our patients.


Preparing for the NCCAOM Exam

Understanding and mastering the clinical applications of the Yang Wei Mai is crucial for passing the NCCAOM exam. Here are some study tips to help you retain the material:

1. Create Visual Aids

Draw the pathway of the Yang Wei Mai and mark the key points. Visual learning aids can be a great help in retaining complex pathways.

2. Practice Point Location

Using a human model or a fellow student, practice locating the key points along the pathway of the Yang Wei Mai. This hands-on practice solidifies knowledge retention.

3. Use Flashcards

Make flashcards with the names and locations of the key points, as well as the clinical applications associated with these points. Regular review of these cards can enhance memory recall.

4. Apply Knowledge Clinically

Apply your understanding of the Yang Wei Mai in your clinical practice. Try to treat conditions like intermittent fevers, pain on the sides of the body, and ear problems using the opening and coupled points.

5. Join Study Groups

Join study groups with your peers to discuss the Yang Wei Mai. Teaching and explaining the content to others can often clarify your understanding and highlight any areas that need further review.

6. Relax

Lastly, don’t stress over minor variations between different sources, like Maciocia and Deadman. The board exams are unlikely to focus on these discrepancies, so trust in your comprehensive understanding.


IN SUMMARY!!!


The Yang Wei Mai is a vital extraordinary vessel with significant clinical applications. From treating intermittent fevers to addressing side body pain and ear problems, it's an indispensable part of your acupuncture toolkit. As you continue preparing for the NCCAOM exam, focus on understanding the pathway and clinical uses of the Yang Wei Mai.

Keep practicing, stay confident, and remember, you are part of a broader medical community dedicated to improving patient health.


Until next time, God bless and Happy studying and best of luck on your exams!

Dr. Richard Lai DPT LAc:


Everyone, welcome back to Study Acupuncture with Me. So in this episode, we're gonna go over the Yang Weimai, and we're gonna go over the 3 clinical applications of the Yang Weimai, which are, number 1, it can treat intermittent fevers. Number 2, it can treat the sides of the body. And then number 3, it can treat ear related issues. Now to understand these clinical applications, we have to talk about the Yang Weimai as a whole. Now the Yang Weimai is also known as the Yang linking vessel, and that's because it actually links all of the yang channels. Now just like with all the other extraordinary vessels, the Yang Weimai also has an opening point and a coupled point. Now the opening point and the Couple point can be used to activate the Yang Wei mai.


Dr. Richard Lai DPT LAc:


Now the opening point of the Yang Wei mai is Sanjiao 5, and the couple point of the Yang Wei mai is gallbladder 41. So now let's look at a diagram of the Yang Weimai, which, as you can see here, the Yang Weimai, it starts with u b 63. So it goes from u b 63, it goes to g b 35. And where's g b 35? It's on the side of your lower leg. The Yang Wei mine also goes up The outside of your thigh along your IT band. It goes up to GB 29, and GB 29 is one of my favorite points to needle for hip pain and for IT band pain. Now this point is located halfway between your As is and your greater trochanter. And then From g b 29, the Yang Wei Mai goes up the side of your abdomen and actually goes below your armpit, and it goes to your shoulder area.


Dr. Richard Lai DPT LAc:


Now in this area, the Yangwei Maya does a lot of zigzagging back and forth, and it goes back and forth between points on your San Jiao, your small intestine, your large intestine and your gallbladder channels. So the Yang Wei mai shares points here with Sanjiao 13, Sanjiao 15, small intestine 10, and large intestine fourteen. It also shares points with gallbladder 21. Now from there, the channel is gonna go up the side of your neck, and it's gonna go behind your ear. Now here's where the Yang Wei mai is gonna finish off its pathway. So it's gonna go from g b 20 all the way to gallbladder 13. And this pathway that I just talked about is actually referenced from Maciocia. Now if you're looking at dead men, you might notice that there's a difference between Dedman and Maciocia, which we're gonna review that difference right now.


Dr. Richard Lai DPT LAc:


So here's a side by side of the points from Maciocia and the points from Dedmon, which from Dedmon, we do have more points here. And we have some points that Mathieuja doesn't reference. Like, for example, Deadman has DUE 16. It also has DUE 15. There's also stomach 8 there. Now Maciocia doesn't have those points. Matchocha has gallbladder 29, it has l I 14, and it has Zhengzhou 13, whereas Deadman doesn't have those points. And if you look at the ear area, machiocha goes behind the ear, and deadman, where does it go? It goes in front of the ear.


Dr. Richard Lai DPT LAc:


So the question is, mind. Should you be stressed about this difference? And the answer is a resounding no because the board exam is mind. Highly unlikely gonna dig itself into a hole by asking you a controversial question like this. They're not gonna ask you to delineate the differences between Maciochan Dedmon. Because if they do, they're gonna receive a literal ton of emails, phone calls, and letters about how, hey. Dedman says this or Maggio just says this. So the board exam isn't trying to get themselves into any trouble in this way. So take a deep breath, relax, And let's move on to talking about the 3 clinical applications of the Yang Wei mai.


Dr. Richard Lai DPT LAc:


Starting with number 1, the Yang Wei mai can be used to treat Intermittent fevers. So the question is, what is an intermittent fever? Now an intermittent fever is a fever that goes up And then it goes back to normal. And then after some time, the fever goes back up again. So the Yang Weimai can be used to treat this kind of fever, which is an intermittent fever. Now the Yang Weimai can also be used to treat alternating chills and fevers. Now you might be wondering, what's the difference between an alternating and an intermittent fever. And the alternating one alternates back and forth between fevers and chills. So it goes back and forth between the 2 states.


Dr. Richard Lai DPT LAc:


There's a state of fever and there's a state of chill. There's an actual flip. Intermittent fever, on the other hand, it just goes from fever and then back to normal. And then after some time, it goes back up to fever and then back up to normal again. It's intermittent. So the Yangwei mai, you can actually use it to treat both intermittent fevers and alternating chills and fevers. Now another thing we know about The alternating chill and fever is that it's the cardinal sign of the Shaoyang stage. The Shaoyang stage is a stage in the six stages theory.


Dr. Richard Lai DPT LAc:


So in the Shaoyang stage of the 6 stages theory, primarily what you're gonna see is this alternation of chills and fevers. And why this is happening? It's because the pathogenic factor is halfway between the interior and the exterior. And we know that when the pathogenic factor is Fully in the interior, that's when we're gonna see this appearance of signs of heat, and we're gonna see a disappearance of the complaints of colds, which you see this with the Yang Ming stage of the six stages theory. Alright. Now clinical application number 2 Of the Yang Wei mai is that you can use it to treat issues with the sides of the body, and this is really apparent when you look at the pathway of the Yang Wei mai. So besides using achi points, you can also use the opening point and the couple point of the Yangwei mai, especially if your patient's presenting with issues like mind, pain on the sides of their body. So some examples of pain on the sides of their body are things like IT band syndrome, osteoarthritis, degenerative disease. Or maybe they have kidney related issues, which with all these, it's always a professional idea to refer your patient to their primary care or even a specialist if you're finding that they need further evaluation on their complaints.


Dr. Richard Lai DPT LAc:


Alright. Now lastly, we have clinical application number 3, which is that the Yangwei mai can be used to treat ear problems. Now ear problems, it can range from ringing in the ears to deafness to pain in the ears or any other ear related problem. And this is because of the pathway of the Yang Wei mai, which we saw before in machiocha and deadman. It says it goes towards the ears. It goes past the ears. One of them, it goes in front. One of them, it goes behind.


Dr. Richard Lai DPT LAc:


But the point is that it allows you as an acupuncturist to treat the ear. And you can use it to treat the ear with any of those shared points that we talked about before, or you can simply activate the Yang Wei Mai through the opening and coupled points. And here, I wanna mention it again because we, as acupuncturists, we are part of the medical community. So when it comes to the betterment of our patients, It's always a good idea to have more clinicians weighing in on any unclear presentations. So for example, if your patient is presenting with those ear related problems, One of the first questions that we need to ask them is, have you seen your primary care physician, or have you seen an ear, nose, and throat doctor? And if they have already, I would, as a professional courtesy, ask your patient to bring in any workups that that doctor did because this could include vital information for your treatment. Now another professional action that you can take is to keep that primary care physician or that ENT doctor updated on that patient's progress in acupuncture. Now how do you accomplish this? You can accomplish this through typing up of a 1 pager of your findings. Now that could include your evaluation findings, the treatments that you did with the patient, any objective measures that you're taking with your patient that can show progress with their treatments.


Dr. Richard Lai DPT LAc:


And you can share this with your patient, And they can provide it to their primary care physician on their next checkup. Because remember, we as acupuncturists, we're part of the medical community. So communicating with their primary care and them communicating back to us is a professional courtesy. And that actually brings us to the end of this episode on the Yang Wei Mai. So as always, until next time, god bless, and happy studying.
