Aleppo Oak or Manjakani (Quercus infectoria) is a species of the oak tree that has been used for centuries in Asia traditionally for treatment. The tree is native to southern Europe (Greece and the Eastern Aegean Islands) and the Middle East (Turkey, Cyprus, Iran, Iraq, Kurdistan, Lebanon, Syria, and Israel). It is also found growing in South and Southwest Asia.
The name “Manjakani” itself is used in Malaysia to refer to Galls (a type of swelling growth in the external tissue of plants). Galls from the Manjakani tree have been used for hundreds of years to soften the skin and make black ink dyes.
These galls appear on the young branches of the Aleppo Oak tree when the wasp of the gall stings the tree and stores their larvae. The chemical reaction of a wasp sting causes abnormalities in the tree and causes small, hard balls.
Aleppo Oak galls have also been pharmacologically documented to have astringent, antidiabetic, antitremorine, local anesthetic, antiviral, antibacterial, antifungal, larvicidal, and anti-inflammatory activities.
Various pharmacological activities of this tree might support the efficacy of the preparation of Aleppo Oak extract which is widely used in Malaysia to treat various health problems since a few decades ago. Nutgalls have been pharmacologically documented in their antiamoebic, anticariogenic and anti-inflammatory activities, to treat skin infections and digestive disorders.

In its habitat, Aleppo oak trees grow at an altitude of 1,800 m above sea level. He prefers moist and heavy soils such as clay, acid soils, neutral soils, and alkaline soils. The tree can grow in a bit of shade but does not tolerate shade.
Historically, Aleppo oak has many uses for medicine, especially traditional medicine. Starting from the bark, leaves, until the fruit has an important role in the raw materials for the manufacture of modern medicine today.
