來自蘋婆屬各物種的樹膠分泌物，尤以來自刺激蘋婆（原生於印度中部與北部的喬木物種）者最為著名。呈大小不一的淚滴形，外觀稍具結晶狀，半透明、淡黃色、微帶酸味、具黏性，嚐起來為略酸的黏液。該樹膠不溶於酒精，在水中會膨脹形成凝膠，與少量水混合即可形成黏性極強的膠黏劑。用作為染料增稠劑、織物塗層、乳化劑、紙纖維黏結劑、大理石紋紙的基底、醫療膠黏劑、牙科膠黏劑、食物增稠與黏合劑，以及作為瀉藥；也可摻雜在黃耆膠中，因二者之物理特性很相似。刺梧桐膠自1920年以後才大量生產於市面上販售。

刺激蘋婆(種)

英文....

Gummy exudate from various species of the genus Sterculia, notably from S. urens, a tree native to central and northern India. It occurs as tears of variable size and of a somewhat crystalline appearance, translucent, pale yellow, with a slightly acetic odor and a mucilaginous, slightly acetic taste. The gum is insoluble in alcohol, but swells in water to form a gel; it forms an extremely strong adhesive with small amounts of water. It is used as a dye thickener, textile coating, emulsifier, paper fiber binder, a base in marbling paper, medical adhesive, a denture adhesive, a thickener and emulsifier in foods, and as a laxative. It is also used to adulterate gum tragacanth due to their similar physical characteristics. Gum karaya has been available commercially only since 1920.
