Hey hey, do you want to make pine needle tea? There are few pine trees in general communities and parks. Not all pine needles can be eaten. Choose uncontaminated ones. Generally, the older the tree, the higher its medicinal value. Only Pinus massoniana and Pinus koraiensis can be used as medicine. Korean pine is mostly distributed in some areas of Northeast China. If we compare two kinds of pine needles, the medicinal value of Korean pine is not higher than that of Pinus massoniana, and the medicinal value of Korean pine is the highest. Because Hengshan is located in the selenium-rich zone, with low latitude and abundant rainfall, the contents of proanthocyanidins and selenium in pine needles produced in Hengshan are much higher than those produced in other areas. You can also come to my space to have a look. There are many introductions about pine needles in it. Hehe, I hope I can help you.
