may be combined with Ba Zhen Wan (Eight Pearls Pills). If there is a liver-spleen disharmony with blood
vacuity, it may be combined with Xiao Yao Wan (Rambling Pills). If liver depression has transformed
heat, it may be combined with Dan Zhi Xiao Yao Wan (Moutan & Gardenia Rambling Pills).
FORMULA EXPLANATION:
In Chinese medicine, migraine headaches are referred to as pian tou tong (side head pain). However,
they are also referred to as pian tou feng (side head wind). This last term suggests that all migraines are
associated with an element of wind. That wind may be either externally contracted or internally engendered.
Signs and symptoms of wind in the case of migraines include paroxysmal attacks which affect the upper-
most part of the body, numbness and tingling, and dizziness and vertigo. Because the pain is very intense
and commonly localized in one or two places, there is also blood stasis in the network vessel. This is
based on Ye Tian-shi’s famous statement that new diseases are in the channels, but old or enduring diseases
enter the network vessels. Because there is static blood in the network vessels, the disease is recalcitrant
to treatment and requires special medicinals which free the flow of the network vessels.
Although 25% of the population suffers from a migraine headache at some point in their life, most
patients with recurrent migraines are females, and, typically, migraines in females occur in relationship
to their menstrual cycle, coming either before, during, or soon after menstruation. This means that
female migraines are commonly associated with blood vacuity failing to nourish the liver properly.
During the premenstruum, blood is sent down to the uterus. If the woman has a relative insufficiency
of blood, this may leave the liver malnourished. Therefore, the liver qi fails to do its duty of governing
coursing and discharge. Instead, the liver becomes depressed and the qi becomes stagnant. This may
give rise to depressive heat which then engenders ascendant yang hyperactivity. It may also give rise to
internal stirring of wind. Further, it may cause spleen vacuity which results in a defensive qi vacuity and
easy entrance and attack by external wind evils. Likewise, loss of blood during menstruation and an
emptiness of the sea of blood post-menstrually may also give rise to any of the above scenarios. If spleen
vacuity engenders dampness and dampness congeals into phlegm, phlegm turbidity may be drafted
upward with counterflowing qi and yang. In somewhat older women, yin vacuity may fail to control
yang. thus leading to ascendant liver yang hyperactivity.
Within this formula, Bai Zhi, Man Jing Zi, and Bai Ji Li scatter wind, free the flow of the network vessels,
and stop pain. Jiang Can, Quan Xie, and Wu Gong track down wind, free the flow of the network
vessels, and stop pain. Chuan Xiong moves upward to the head and eyes and downward to the sea of
blood. It moves the qi within the blood and dispels wind within the blood. It quickens the blood and
transforms stasis as well as moves the qi and stops pain. Dang Gui, Dan Shen, and Bai Shao both nourish
and quicken the blood, relax cramping or spasm, and stop pain. therefore, when all these medicinals
are used together, they track down wind and free the flow of the network vessels, quicken the blood,
dispel stasis, and stop pain.
In a study of 42 patients 15-56 years old, 28 of whom were female and who had suffered from migraines
for from 1-30 years, this formula achieved a 92.9% total amelioration rate. Eleven out of 42 cases were
cured, 18 got a marked effect, 10 got some effect, and only three failed to experience any improvement.
This was compared to a comparison group of 42 similar patients treated with Western medicine which
only achieved a 73.8% total amelioration rate and only half the cure rate.1
This formula contains Quan Xie (Scorpio) and Wu Gong (Scolopendra), both
potentially toxic substances. However, cooking, as in the manufacture of
this product, mostly destroys these toxins. The toxic dosage in decoction of
these two substances is 30-60 grams per day. Each of these ingredients
represent 3% of our formula. The amount of these two substances in six
capsules per day is the equivalent of 0.18 grams per day in decoction or
.006% of a toxic dose. Therefore, practitioners do not need to worry about
the toxicity of these ingredients in this formula.
