Forsythiae Fructus (Lianqiao), Epimedii Herba Spatholobi Caulis? No, Qumai (Spermacoce Herba), Talcum (Huashi), Plantaginis Semen (Cheqianzi), Arctii Fructus (Niubangzi) [stir-fried], Paeoniae Radix Rubra (Hong Shaoyao) (each 1 liang), Gardeniae Fructus (Shanzhi), Akebiae Caulis (Mutong), Angelicae Sinensis Radix (Chuan Danggui), Saposhnikoviae Radix (Fangfeng) (each 0.5 liang), Scutellariae Radix (Huangqin) [heart removed, 1.5 liang], Bupleuri Radix (Chaihu) [rhizome removed], Glycyrrhizae Radix et Rhizoma (Gancao) [roasted, each 2 liang], Schizonepetae Spica (Jingjie Sui) (1.5 liang), Bombyx Batryticatus (Chantui) [large legs removed, 1 liang].

The above fifteen ingredients are coarsely powdered. For each dose, take 1 da liang, decoct with one small cup of water, prepare the decoction in advance.

Discussion: This formula resolves and benefits Heart Meridian pathogenic heat. The Heart and Small Intestine are interior-exteriorly related; the Small Intestine is the "water channel" (shuidou) responsible for receiving and transforming fluids, and should always be kept patent and draining. Stagnation leads to accumulation; patency leads to discharge; heat leads to astringency; excess heat leads to strangury. Cooling the Heart Meridian ensures the smooth flow of the Sanjiao (Triple Burner). One need not wait for the disease to manifest to resolve it, nor treat after symptoms have formed; such delay is negligence.

With the fifteen ingredients and the aforementioned decoction method, as soon as one perceives internal accumulated heat or external invading heat, if wind-cold pathogens enter the Lung Meridian and the Heart is about to be affected but has not yet been directly touched, the pathogen transmits to the Small Intestine. This may cause urinary obstruction or astringency, urine color red or white, dribbling strangury without relief, and disharmony of Ying (Nutrient) and Wei (Defensive) Qi. Stagnation gives rise to disease with diverse manifestations, including diaphragmatic heat, redness of eyes and chest (danchi), sores on lips and mouth, absence of body fluids, and thick nasal discharge and saliva. Whether the pathology is in the exterior or interior, this formula is suitable; it can disperse convulsions and wind, and eliminate phlegm-heat. The efficacy of Forsythiae Fructus (Lianqiao) is indeed not in vain.

Artemisiae Annuae Herba (Qinghao) [use flower heads, soak in child's urine once or twice, dry until ready], Bupleuri Radix (Chaihu) [rhizome removed], Ginseng Radix et Rhizoma (Renshen), Scutellariae Radix (Huangqin) [heart removed], Peucedani Radix (Qianhu), Gentianae Macrophyllae Radix (Qinjiao) [soil removed], Glycyrrhizae Radix et Rhizoma (Gancao) [roasted].

The above seven ingredients are coarsely powdered. For infants aged one year, take half a liang; for two-year-olds, take one liang bi (spoonful). Decoct with one small cup of water, adding fresh lotus root, fresh pear (pear strips are also acceptable), two leaves of Mentha Haplocalyx (Bohe), and one cun of Rehmanniae Radix Recens (Sheng Dihuang). Decoct until the volume is reduced by half, strain, and drink warm on an empty stomach before meals. Combine the dregs from the first and second decoctions to make one final dose.

Discussion: This formula treats spleen accumulation causing alternating chills and fever, resembling malaria. This arises from the competitive struggle between Yin and Yang Qi of the Spleen. Chills appearing first indicate Yin exceeding Yang; fever appearing later indicates Yang exceeding Yin. Following the meridians, the transmission returns to the primary organ, recurring based on previous patterns, stopping within three days. In severe cases, headache and vomiting occur; in chronic cases lasting two to three years, there is no respite, and a mass appears in the left hypochondrium, small like plum or peach, large like a city wall parapet. The treatment method involves removing the accumulation and masses, which will then dissipate spontaneously. However, the alternating chills and fever cannot resolve themselves; one must first administer Pear Syrup Drink (Lijiang Yin), taking the dregs along with the liquid, divided into three doses. Only after the chills and fever are stabilized can one proceed to administer purgatives for the accumulation. Someone asks: The drug properties are cold and cool; how do they resist the pathogen? The answer is: The so-called "chills first, fever later" resembles the alternating victory and subjugation of Yin and Yang. Yin accumulation and Yang deficiency lead to reversal. Conversely, extreme cold generates heat, and extreme heat generates Yin, leading to spontaneous sweating and slight relief at the exterior, but Qi aggregation causes recurrence, worsening Qi deficiency. The administered Pear Syrup Drink uses toxicity to attack toxicity, employing cold drugs to counteract cold pathogens. If the heat is not present, it certainly will not worsen; naturally, the drug harmonizes with Wei Qi and combines with Yin Qi. It is unprecedented for chills and fever to surge again. The efficacy of Pear Syrup Drink is exquisite and unparalleled; those who understand its application will achieve recovery. Even if the illness has persisted for three years, two doses suffice; even if experienced for ten years, this formula's pure and subtle application inspires admiration.
