Peach gum is a resin secreted by bark, also known as peach oil, peach gum and peach paste. Peach trees naturally secrete or produce wounds under the action of external force, and the secretion of peach gum is beneficial to the self-healing of wounds and the production of solids.
Collected in summer and autumn, its composition is roughly the same as Arabic gum, and some of it is mixed with impurities. The fake peach gum has the same size, no impurities and no faint fragrance.
Dried peach gum is as hard as crystal stone and looks a bit like amber. Peach gum has enough water solubility and proper viscosity, and it becomes soft after being soaked in clear water for more than ten hours.

Production of peach gum
The branches of peach trees swell, and then light red yellow transparent resin flows out, and the color of jelly gradually turns light red. If the weather is dry, the gel will turn into a reddish crystalline lump.
After the rain, there are a lot of gums, most of which are light yellow or white transparent solids after drying, because the rainstorm makes peach trees absorb a lot of water, and after diluting the gums in the body, the first batch of gums are light yellow or white transparent gums.
The secretion of peach gum is mainly caused by trunk damage or fungal infection, which is the self-defense mechanism of peach trees.
