Fa Nao (Brain Abscess/Carbuncle) arises from the disharmony of the Six Fu Organs, obstruction and stagnation of the meridians, and the failure of Qi and Blood to circulate, leading to accumulation and knotting. This is generally caused by the accumulation of Heat-Toxin within the Zang-Fu organs, or a history of ingesting Ru Shi (Mineral Drugs).
If Fa Nao is not treated promptly by puncturing acupoints to drain pus, after the pus is discharged, pain and distension may worsen. Heat may disturb the brain, causing sensations as if chariots and horses were moving, with unbearable pain. In such cases, Xijiao San (Rhinoceros Horn Powder) should be used.
Formula:
Xijiao Xie (Powdered Rhinoceros Horn, 1 liang), Shigao (Gypsum Fibrosum, 2 liang), Mutong (Caulis Akebiae, 1 liang, sliced), Chuan Shengma (Radix Bupleuri, 1 liang), Xuanshen (Radix Scrophulariae, 1 liang), Gancao (Radix Glycyrrhizae, 0.5 liang, raw, sliced), Chi Shaoyao (Radix Paeoniae Rubra, 1 liang), Huangqin (Radix Scutellariae, 3 fen, sliced), Chuan Pu Xiao (Natrii Sulfas, 2 liang).
Preparation: Pound and sieve the above ingredients into a powder. Take 4 qian per dose. Add one zhong of water, decoct until reduced to 6 fen. Strain and take warm at any time. If the sore has not yet ulcerated, this formula is highly effective.
