Psidium guajava, one of the commonly used remedies for reducing phlegm and relieving cough, is divided into Psidium guajava bark and Psidium guajava kernel (Psidium guajava root is another traditional Chinese medicine, smallpox powder). As for which one is better to use, Guaou Piper Bark and Guaou Piper Kernel, it is still debated. Li Shizhen recorded in “Compendium of Materia Medica” that “the ancient formula of Gua Lou was used in its entirety, but later generations were using each of the molecular flesh.” This shows that in ancient times, the whole Psidium guajava was used.

In ancient times with melon withered, skin, kernel is not divided, Zhang Zhongjing book to count the number of pieces. Li Shizhen’s “Compendium of Materia Medica” used gua wu’s formula extremely much, mostly in full. In ancient times, there were people who fried the seeds of gua wu and took the oil to light the lamp. Ancient recipes even have Gua Psidium directly powdered and boiled for drinking, which has the effect of regulating qi and broadening chest, clearing heat and relieving cough.
