Li Dongyuan's Encyclopedia of Medicine wrote: "Xiao Pi Pill" is used to treat heart fullness, all trauma and those who have not healed for many years.
Dried ginger, fried Massa Medicata Fermentata, Radix Glycyrrhizae Preparata (20 cents each), Polyporus (25 cents each), Rhizoma Alismatis, Cortex Magnolia Officinalis, Fructus Amomi (one each in San Qian), Rhizoma Pinelliae, Pericarpium Citri Tangerinae, Radix Ginseng (one each in four lines), Fructus Aurantii Immaturus (50 cents each), Rhizoma Coptidis, Scutellariae Radix (60 cents each), Rhizoma Curcumae Longae, and Atractylodis Rhizoma (one each in four lines
Li Dongyuan's prescription is obviously from the perspective of internal injuries. Look at his recipes. It's a little messy Zingiberis Rhizoma, Radix Glycyrrhizae Preparata, Rhizoma Pinelliae, Ginseng Radix, Scutellariae Radix, Coptidis Rhizoma. This is Banxia Xiexin Decoction. Besides jujube, other medicines such as Polyporus, Alisma orientalis and Atractylodes macrocephala were added. If there is cassia twig and poria cocos, it is Wuling powder, as well as ginseng, dried ginger, licorice and atractylodes macrocephala. This is Lizhong decoction, Magnolia officinalis, ginger, Pinellia ternata and licorice. Massa Medicata Fermentata, Fructus Amomi, Atractylodis Macrocephalae, Pericarpium Citri Tangerinae, Poria, Pinellia ternata, Fructus Aurantii Immaturus, Magnolia Officinalis, Glycyrrhrizae Radix and Curcuma Rhizome are a bit like Xiangsha Yangwei Pills.
Li Dongyuan added jujube to Banxia Xiexin Decoction, and added large doses of Atractylodes macrocephala and Fructus Aurantii Immaturus. This is not adding Fructus Aurantii Immaturus Pills, but adding Banxia Xiexin Decoction to Fructus Jujubae and Fructus Aurantii Immaturus Pills. On this basis, adding Massa Medicata Fermentata, Polyporus, Alisma orientalis, Magnolia Officinalis, Amomum villosum, Pericarpium Citri Tangerinae and Curcuma longa is equivalent to changing Mude into Curcuma longa, and changing Amomum tsaoko into fragrant sand and stomach nourishing pills of Massa Medicata Fermentata, namely Banxia Xiexin Decoction combined with Zhi Zhu pills and fragrant sand and stomach nourishing pills.
This prescription looks a bit messy, but its main prescription is clear. There is a difference between Banxia Xiexin Decoction and Zhi Zhu Pill, that is, the dosage of Scutellaria baicalensis Georgi and Coptidis Rhizoma is slightly larger, and the dosage of dried ginger is small, while the dosage of Magnolia officinalis, Amomum villosum and Atractylodes macrocephala used by him is large.
Li Dongyuan's other prescription is called Shixiao Pill (also called Zhishi Xiao Pi Pill), which is used to treat right hand pulse string, guilty conscience and fullness, aversion to food, laziness and tiredness, and to stimulate appetite into the diet.
Dried ginger (one yuan), Radix Glycyrrhizae Preparata, Fructus Hordei Germinatus, Poria, Rhizoma Atractylodis Macrocephalae (two yuan each), Rhizoma Pinelliae, Radix Ginseng (four yuan each), Cortex Magnolia Officinalis (four yuan each), Fructus Aurantii Immaturus and Rhizoma Coptidis (five yuan each).
Dried ginger, licorice, Pinellia ternata, ginseng, Coptis chinensis. Of the seven herbs of Banxia Xiexin Decoction, Li Dongyuan used five herbs, except Scutellaria baicalensis Georgi and Jujube. On this basis, he added Atractylodes macrocephala and Fructus Aurantii Immaturus, which means Fructus Aurantii Immaturus Pill. The standard Fructus Aurantii Pill is that the dosage of Atractylodes macrocephala is greater than that of Fructus Aurantii Immaturus. If ginseng, Atractylodes macrocephala, Radix Glycyrrhizae Preparata and Poria are combined, it is Banxia Xiexin Decoction and Sijunzi Decoction.
Let's look at another prescription of Li Dongyuan: Huanglian Xiao Pi Pill, which is used to treat fullness, stagnation and anxiety.
Alisma orientalis, Curcuma longa (each 1 yuan), Zingiberis Rhizoma (2 yuan), Radix Glycyrrhizae Preparata, Poria, Atractylodis Rhizoma (each San Qian), Pericarpium Citri Tangerinae, Polyporus (each 5 yuan), Fructus Aurantii Immaturus (fried 7 yuan), Rhizoma Pinelliae (fried 9 yuan), Rhizoma Coptidis (fried 1.2 yuan), Scutellariae Radix (Radix Scutellariae).
Pinellia Xiexin Decoction uses dried ginger, roasted licorice, Pinellia ternata, Coptidis Rhizoma and Scutellariae Radix, and ginseng and jujube are removed. Then add Alisma orientale, Poria cocos, Atractylodes macrocephala and Polyporus, which is Sini powder, namely Banxia Xiexin Decoction and Sini powder, and add turmeric for promoting blood circulation, tangerine peel for regulating qi and Atractylodes macrocephala.
In other words, Banxia Xiexin Decoction can be compatible with Sijunzi Decoction, Sini Powder, Zhi Zhu Decoction and Zhi Zhu Pill.
