Abu Rayhan Muhammad Ibn Al-Biruni (1050-973 AD) probably for the first time expressed the opinion that the gum obtained from the plant called "Hajj" can be said to be synonymous with the real mind. Turnjbin is a corruption of the Persian word trangbin. Angbin is called honey in Persian as if Trangbin is the same thing which is called Honey Dew in English. In this way, the gum extracted from "Hajj" was also considered as sweet and useful as honey. For centuries after Al-Biruni's research, no scientific observations were made that would provide accurate information about the flora of Sinai and other parts of the Arabian Peninsula. In his book Travels in Syria and Holy Land, it is written that there are certain types of insects responsible for the production of manna, which make holes in the bark of some trees and give off a moisture during extreme heat. I freeze on trees. Barkhard's idea was reinforced in 1829 when Ahernberg and Ham Paresh scientists published a report stating that an insect called Cocus manniparus was found on a plant called Tamarks in the Sinai Desert which produces manna. It seems that in the first half of the nineteenth century, it became clear that the mind grows on the trees of Sinai, which is very sweet. The gum (man) extracted from is eaten as a sweet.
