LI-4 (headache, arm or facial pain, infection, hot flashes)

LI-4: Hegu. This point is astonishingly useful for a wide variety of complaints, but don’t use it if your patient is pregnant!

Large Intestine 4 is the acupoint most well-known by the general public. I first had it taught to me by a riding instructor when I was a kid living in rural Virginia. The name for this point is Hegu, “Joining Valley,” which is a reference to its anatomical location on the back of your hand, in that fleshy area between the thumb and forefinger. Feel around – it’ll be tender if you need it – but the easiest way to find it is to squeeze your thumb against your hand. The highest point of the muscle is where you want to press. Use firm, gentle pressure for 10-20 seconds with a healing intention. Try both sides.

Hegu, or Joining Valley, is a tremendously useful point. It moves stagnation, so you can use it to clear pain and stiffness anywhere in the upper body. Hegu will be particularly effective along the LI channel, which runs from the nail of the forefinger, along the forearm to the lateral (outside) elbow, up the arm and across the shoulder, eventually crossing the upper lip to end at the opposite side of the nose. Shoulder and elbow pain, carpal tunnel, and (of course) headaches are common uses. It’s specifically the Ruler of the Face, so it’s doubly powerful for frontal headaches, eye pain, sinus blockage, and tooth pain. It also releases heat and is part of a point combination for fighting viral or bacterial infections. If  you are prone to hot flashes, this point could be your new best friend. Also use LI-11, pictured here, to clear heat.

And by the way… the leading cause of headache is dehydration. Drink a glass of water!

WARNING: Because Hegu is a moving point, DO NOT use it if you are pregnant or bleeding. It can induce a miscarriage or increase blood loss. On the other hand, if you are overdue and want to evict your baby, this is a great way to do so, along with some other points (assuming everyone is healthy and it’s not a complicated pregnancy!). It will usually increase menstrual flow if the patient is having her period. If you have a severe headache paired with sudden loss of motor control or speech, get to a hospital immediately. DO NOT use LI-4 until you are sure you are not having a hemorrhagic stroke (bleeding inside the brain). This goes for head injuries, too!
