Infusion of Catechu, commonly called Japonic Infusion

March 3rd, 2016

Take of

  • Extract of catechu, two drachms and a half;
  • Cinnamon, half a drachm;
  • Boiling water, seven ounces;
  • Simple syrup, one ounce.

Macerate the extract and cinnamon in the hot water, in a covered vessel, for two hours, then strain it, and add the syrup.

Extract of catechu is almost pure tan[n]in. This infusion is therefore a powerfully astringent solution. The cinnamon and syrup render it a very agreeable medicine, which will be found serviceable in fluxes proceeding from a laxity of the intestines. Its dose is a spoonful or two every other hour. As this preparation will not keep above a day or two, it must always be made extemporaneously. The two hours maceration, therefore, becomes very often extremely inconvenient; but it may be prepared in a few minutes by boiling, without in the least impairing the virtues of the medicine.
