The first edition of "Heji Jufang" was published during the Northern Song Period and then revised numerous times. The most commonly used edition of "Heji Jufang" is divided into six pharmacopoeias. This paper reports, the results of this author's examination of the methods and intentions of the revisions made to the "Heji Jufang". At the time that the Shaoxing pharmacopoeia was edited, the same prescription was shown to be given to plural illness divisions. The Xutian pharmacopoeia, which was expanded by Xuhong, includes over 80 prescriptions that are not included in the most commonly used edition today. The method of revising the Baoging pharmacopoeia was to transfer prescriptions of the Xutian pharmacopoeias to the Baoqing pharmacopoeia (the main body of pharmacopoeias). This means that these prescriptions were upgraded to formal pharmacopoeias from supplemental pharmacopoeias. The revision of the Chunyou pharmacopoeia was performed as follows. (1) The main body of "Heji Jufang" was divided into four pharmacopoeias: Daguan, Shaoxing, Baoqing, and Chunyou. (2) For divisions left with no or few prescriptions, prescriptions were incorporated from other divisions. (3) Generally, prescriptions were incorporated to the main body of the pharmacopoeias from supplemental pharmacopoeias. (4) Unnecessary prescriptions in the Xutian pharmacopoeia were deleted.

This paper summarizes how Gambir entered China. While the author attempts to explain how Gambir was replaced by tea in the area, there still appear to be many missing links, to which the author would like to welcome constructive criticism. Lao-cai on the China-Vietnam border, where Acacia pads were produced up to the 16th century, can be read as Rakuju . A tribe that belongs to Hani in northern Laos also consumes these Acacia pads. It was Li Jichin who called tea Lau-nu. This was based on a historical fact that Oh Shuku pointed out to Emperor Kobun in the 5th century in Northern Wei that calling tea a slave of lactic products could not be considered appropriate.

The usage of Shu wei cao as a coloring matter was described for the first time in Er Ya as the name of Jing shu wei. But, in modern Chinese and Japanese literature, few papers reported the use of Shu wei cao as a dye. As a herbal medicine, it seems that it was first described in Ming Yi Bie Lu. In this study, we found that in Chinese and Japanese literature, there is much confusion about the origin of Shu wei cao. It is likely that the original plant of Shu wei cao is to be Salvia japonica Thunb. In Japan, it is feasible that Shu wei cao is to be recognized as Aki-no-tamura-so, while some suggested that misohagi (Lythrum anceps Makino) was identical to Shu wei cao.
