Why we bleed patients on purpose

As Chinese medical practitioners we have a variety of modalities to choose from. Most, if not all, of our patients receive acupuncture and cupping, maybe some moxa now and then, or some tension relieving guasha. Digging deeper into the Chinese medical toolbox reveals treatment options that are less well known AND can be incredibly effective in the proper circumstances.

One of these lesser known treatments is micro-letting, AKA using a small lancet to prick an area of the body and draw a few drops of blood. Micro-letting is traditionally part of both Chinese and Ayurvedic medicines, along with many other traditional medical systems. And if you’re thinking, “That sounds positively medieval,” you’re not alone. However, read on to discover the science behind this powerful treatment tool. It’s going to get a little technical, but I promise you it’s worth it.

Our veins are part of two distinct circulatory systems:

  • the deep venous system 

  • the superficial venous system

An example of the superficial system are those veins you can see in your arms and legs.  

The deep veins lie deeper in our muscle tissue, underneath our fascia (sheets of connective tissue that attach, stabilize, and separate muscles and other internal organs.) The depth of this system allows the deep veins to operate under higher pressure and handle higher volumes of blood.  

The two systems are connected by perforating veins, so-called because they perforate the fascia.

The efficiency of blood flow in the deep veins depends on venous pressure vs. tissue pressure:

  • Venous pressure is the pressure pushing the blood through the veins back to the heart

  • Tissue pressure is the pressure exerted against the deep veins by the tissue surrounding them

If you experience an injury or inflammation, swollen tissues press against the deep veins, impeding blood flow back to the heart.

Our friends the perforating veins offer an alternative route for blood flow back to the heart, so if blood is having trouble flowing through the deep veins in a particular region of the body, blood can travel through the perforating veins to the superficial veins and then back to the heart.

In other words, our venous system acts like an intricate highway structure where if one portion of the road is congested with lots of traffic, you are rerouted to another road that can get you to your destination quicker. Micro-letting is the tool we use to reroute blood flow when it’s congested and is having issues reaching its desired destination.

Take for example compartment syndrome. This is when tissue pressure in an area of the body is greater than venous pressure in that area.

This happens typically after an injury. The tissue swells and presses against the veins, impeding blood flow.  

A similar situation can occur with an inflamed organ, nerve or joint.  

While Western medicine describes a few cases of impaired blood flow in the deep veins such as deep vein thrombosis and compartment syndrome, Chinese medicine recognizes a multitude of different phenomena where increased tissue pressure in joints, muscles or organs can impede venous blood flow.  

By micro-letting blood at appropriate points, we are drawing congestion off the muscle, nerve, artery or organ through the perforating veins. This removal of congestion can relieve pain (sometimes instantaneously!) and dramatically hastens the healing process.  

What can bleeding treat?

Micro-letting is particularly effective for conditions which involve nerves: sciatica, trigeminal neuralgia, optic neuritis, droopy eyelid, nerve pain following surgery, carpal tunnel, shingles pain, neuropathy, etc.  

But it treats much more!  A partial list includes:

  • Acne

  • Joint sprains

  • Neck pain

  • Back pain

  • Facial pain

  • Knee pain

  • Foot pain

  • Rashes and other dermatological conditions

  • Anxiety

  • Arthritis

  • Bell’s Palsy

  • Cardiac conditions

  • Headaches/migraines

  • Concussion

  • Cramps

  • Digestive complaints (Crohn's, IBS, IBD, reflux)

  • Painful periods and other gynecological conditions

  • Hemorrhoids

  • High blood pressure

  • Insomnia

  • Liver conditions

  • PTSD

  • Sore throat

  • Spider veins

Isn’t it nice when something so simple can be so effective?

How I healed a sinus infection without antibiotics

Last weekend Minneapolis had a heat wave and while everyone else was riding bikes and grilling outside, I was laid up in bed with some very angry sinus pain. Not fun. But that was a week ago, and now this weekend is almost here, and I'm feeling great and ready to get back on the saddle (literally and figuratively).

A few patients this week asked me if I took antibiotics to get over my sinus woes, and were surprised when I told them I didn't. Their next question was always: "How?"

How Do You Know When Acupuncture Is Working?

Many patients visit my clinic as a last ditch effort for their health. They've seen their primary physician, one or many specialists, and possibly other integrative care practitioners before they decide to give acupuncture a shot. By this time, their symptoms may have been present anywhere between 6 months to several decades. At this point, their condition is clinically considered "chronic".

Acupuncture isn't a magic pill. There are times when it can produce almost miraculous results - I've seen it myself - but those are generally the exception, not the rule. You can't expect a chronic condition of several years resolve in one or two sessions. Acupuncture works cumulatively - just like strength training or learning a new language. As I discuss in this blog post, the frequency and length of treatment varies from patient to patient. And while the primary symptoms might not abate in the first few treatments, there are other markers you can look for to know when acupuncture is working for you.

Why All Athletes Should Get Acupuncture

Kobe Bryant does it. So does McKayla Moroney. Dee Dee Trotter even brought someone to London with her in order to continue her treatments during the Olympic games. What’s their secret to functioning at the professional athletic level? Acupuncture.

Once only thought of as a last resort for people with low back pain, people with conditions varying from autoimmune diseases to generalized anxiety are now turning to acupuncture for help. This is especially true for active individuals. Athletes of all levels are embracing the benefits that acupuncture produces: quicker recovery time after strenuous workouts, help healing from injuries, less anxiety during competitions, and the list goes on and on.
