Mayu (galls of Quercus infectoria Oliv.) — commonly called gall oak galls, majuphal, manjakani or Turkish/ Aleppo galls — are hard, rounded excrescences that form on young twigs of Quercus infectoria after attack by certain gall-forming insects. The galls (not the tree wood) are the medicinal material traditionally used; they are strongly astringent because they are rich in hydrolyzable tannins
