The *Zhubing Yuanhou Lun* (Treatise on the Pathogenesis and Symptoms of All Diseases) states: Shan-zhang malaria (Mountain Miasma Malaria) originates in the Lingnan region, caused by inhaling the miasmic qi of the mountains. Its presentation involves alternating chills and fever with regular periodicity. This is due to pathogenic factors combining with the miasmic qi of mountain streams and valleys.
The *Qipo Fang* (Prescriptions of Qibo) essential formula for treating zhang-malaria:
Hengshan (Radix Daphnes, 3 liang), Gancao (Radix Glycyrrhizae, 2 liang), Guangmingsha (Realgar, 1 liang).
Pulverize these three herbs and sift them. Mix with honey to form pills the size of a Chinese quince seed. Take three pills before the onset of the attack, two pills during the attack, and one pill after the attack. Administer another dose for the following three days. Observe dietary restrictions for three days.
The *Luyan Fang* (Verified Prescriptions) method for treating malaria and shan-qi (mountain miasma):
Hengshan (Radix Daphnes, 2 liang), Gancao (Radix Glycyrrhizae, 2 liang).
Slice the herbs and soak in one da-sheng of white wine overnight. Strain out the dregs and divide into two doses. Take one dose before the onset of the attack, and another dose just prior to the attack. Vomiting is permitted. Avoid raw/cold foods, sour substances, and slippery alcoholic beverages.
The *Zhubing Yuanhou Lun* states: Jianri-malaria (Every-other-day Malaria) occurs when pathogenic factors and Wei Qi (Defensive Qi) circulate together through the Six Fu-organs but occasionally fall out of phase and fail to interact properly, causing pathogenic factors to press inward upon the Five Zang-organs.

Shumi (Sorghum Grain, 100 grains), Shigao (Gypsum Fibrosum, 8 liang, crushed), Hengshan (Radix Daphnes, 3 liang), Zhuye (Bamboo Leaf, 3 liang).

The *Duanju Fang* (Short Drama Prescriptions) Hengshan Wine Formula for severing malaria, used when malaria begins with severe chills and trembling, followed by high fever after the chills subside, effective for both daily and every-other-day attacks:
Biejia (Carapax et Plastrum Testudinis, 1 liang), Danzhuye (Light Bamboo Leaf, sliced, 3 sheng), Hengshan (Radix Daphnes, 3 liang), Gancao (Radix Glycyrrhizae, 3 liang), Jiujiu (Aged Wine, 3 sheng).
Take the five ingredients, soak in wine. Place a knife over the vessel and cover it. Set outdoors overnight. On the next morning, add seven sheng of water and boil to obtain three sheng of liquid. Divide into five doses. Ensure all are consumed before the onset of the attack. [Text missing].
The *Fan Wang Fang* (Fan Wang's Prescriptions) Niuxi Wine Formula for treating persistent malaria lasting years:
