When the seasonal pathogenic factor disease reaches the third day, the Shaoyang (Lesser Yang) channel is affected. The Shaoyang channel circulates along the hypochondrium and ascends to the neck and ears. Therefore, after three days of illness, symptoms such as heat in the chest and hypochondrium and deafness occur. At this stage, the meridians of the Three Yang channels begin to transmit the pathogen, but it has not yet entered the Zang organs. Thus, the disease can be cured by inducing sweating.
For the seasonal pathogenic factor disease on the third day, presenting with headache, high fever, mental restlessness and oppression, and discomfort in the chest and diaphragm, Chai Hu San (Bupleurum Powder) is appropriate.
Ingredients: Chai Hu (Radix Bupleuri, removed roots), Ren Shen (Radix Ginseng, removed rhizomes), Xi Jiao (Horn Rhinocerotis, sliced), Huang Qin (Radix Scutellariae), Mai Men Dong (Rhizoma Ophiopogonis, removed hearts) (each 1 liang), Gan Cao (Radix Glycyrrhizae, 0.5 liang, honey-fried until slightly red and crushed), Ban Xia (Rhizoma Pinelliae, 0.5 liang, washed seven times with decoction to remove slipperiness).
Preparation and Administration: The above ingredients are pounded and sieved into a powder. Take 5 qian per dose, add 1 da zhan (approx. 200ml) of water, 0.5 fen of fresh ginger, and 3 dates. Decoct until 0.5 portion remains, strain, and take warm at any time.

For the seasonal pathogenic factor disease on the third day where the exterior syndrome is unresolved and heat toxin transmits, possibly accompanied by vomiting or coughing, Jie Ji Ma Huang San (Muscle-Releasing Ephedra Powder) is used.

Decoct until 0.5 portion remains, strain, and take hot. Follow with Cong Zhou (Scallion Porridge). Sweating indicates recovery; if no sweat occurs, administer again.

Sweating will occur shortly thereafter, leading to recovery.
