回答说：眩，就是头晕。所谓“运”，是指天体运转的意象，世人所说的头昏眼花就是这个意思。“冒”，是蒙蔽的意思，世人所说的神志昏沉就是这个意思。《明理论》中说：“不是毛发却看见毛发，不是黑色却看见黑色。”这是指眼花。眩是指眼前发黑。《针经》说：上部气虚则眩晕，下部气虚则厥逆。眩晕虽然多属虚证，但风病患者也有这种情况，因为风性主动的缘故。妇人头晕，兼有痰湿且经常呕吐的，症状像醉酒后患头风病一样。
芎羌散，治疗妇人患头风病的占十之五六。每次发作必定感到头晕目眩，如同坐在车上颠簸一般。这主要是因为血虚，肝经受风邪侵袭所致。《素问》说：“徇蒙掣急（指眼睛昏花、牵引不适），视物不明，耳聋。下部实而上部虚，病在足少阳胆经和足厥阴肝经，严重时病邪传入肝脏。”说的就是这种情况。此方比其他药物见效更快更迅速。

Answer: "Xuan" (dizziness) refers to a spinning sensation. The term "Yun" implies the motion of celestial bodies, which is what people commonly refer to as head dizziness or vertigo. "Mao" refers to a state of being covered or obscured, which corresponds to the worldly description of mental confusion or stupor. *Ming Lilun* states: "Seeing hairs when there are none; seeing blackness when there is no darkness." This describes blurred vision. "Xuan" specifically refers to dimness or blacking out of vision. *Zhen Jing* (The Classic of Acupuncture) states: "Deficiency in the upper part leads to dizziness; deficiency in the lower part leads to Jue (cold extremities/loss of consciousness)." Although dizziness is often due to deficiency, it can also occur in wind-patterns because wind has the nature of movement. In women, dizziness accompanied by phlegm and frequent vomiting resembles the symptoms of "Drunk Head Wind" (a type of severe headache/dizziness).
Xiong Qiang San (Ligusticum and Notopterygium Powder) treats women suffering from Head Wind patterns, accounting for half of such cases. Each attack is characterized by vertigo as if riding in a carriage. This is primarily due to Blood deficiency with Wind pathogen invading the Liver channel. *Su Wen* states: "Xun Meng Che Ji (visual disturbance and pulling sensations), blindness, and deafness. Excess below and deficiency above, the pathology lies in the Foot Shaoyang Gallbladder and Foot Jueyin Liver meridians, and severely, it enters the Liver." This refers to this condition. This formula acts faster and more effectively than other medicines.

Grind the above into coarse powder. Take 2 qian per dose, add one large cup of water and five slices of fresh ginger, decoct until reduced to 70%, strain, and take warm. Time of administration is not restricted. For Qi deficiency, administer this medicine to deliver Yangzheng Dan (Nourishing Righteousness Pills) 50-70 pills.

Take 30 pills per dose, swallowed with ginger soup or rice drink. Additionally, moxa should be applied to the Guanyuan CV-4 acupoint for 100 moxa cones. Liuhuang Wan (Sulfur Pill) in *Liangfang* is also excellent.

First, boil Pingwei San once. Then add the cake, crush it, and decoct together for one or two boils. Drink all at once.
Taohong San (Peach Red Powder) treats men and women with Qi deficiency where pathogenic factors attack the head and eyes causing dizziness, lateral or frontal headaches, Brain-clamping Wind, pain in both Taiyang acupoints, and pain in the supraorbital ridge.
