<p>Fu Zi patterns belong to water disorders. It explains in Zhang&rsquo;s book that after taking the first dosage of Gui Zhi Fu Zi Qu Gui Jia Zhu Tang there should be general numbness and after the second and third dosages, there will be dizziness. This phenomenon is normal and dizziness indicates Zhu and Fu Zi are moving water. After taking two He of Wu Tou Gui Zhi Tang there will be no reaction. After taking another three He of Wu Tou Gui Zhi Tang and there is still no reaction, take another 5 He of Wu Tou Gui Zhi Tang. If then the patient acts drunk the medicine is effective; if the patient vomits, the medicine has been completely effective.</p>

<p>Fu Zi will cause dizziness once water is eliminated from the body. In severe cases, where the patient appears dead and the pulse is extremely faint. Fu Zi will then cause them to vomit several litres of water and the symptoms will be instantly relieved. I have experienced this reaction many times with Wu Tou Tang. It&rsquo;s concluded Fu Zi expels water.</p>
