Antelope horn is the horn of the male saiga antelope, a bovine species. Domestic production is very small, so there are often fake products on the market that are passed off as the horns of other animals.

Antelope horn is a medicine that calms the liver and calms wind, clears away heat, calms convulsions, and detoxifies. It can cure high fever, epilepsy, coma and convulsions, eclamptic convulsions, and epileptic madness.

True antelope horns are long cone-shaped, slightly bow-shaped, 15 cm to 33 cm long, white or yellow-white, with a slightly bluish-gray base. The young branches have purple-black markings when viewed through perspective, and are as smooth as jade without cracks, while the old branches have fine vertical cracks. In addition to the tip, there are 10 to 16 raised ring ridges with a distance of 2 cm. The four fingers of the hand can fit into the recess. There are hard corner pillars at the base of the horn, accounting for about 1/2 to 1/3 of the full horn. There are protruding longitudinal edges on the surface that are closely integrated with the horn sheath. When viewed in cross section, the joint is serrated. After removing the corner pillars, the entire corner is white or yellowish-white and translucent. Under light perspective, there is a white or approximately visible pore in the center of the upper half that leads directly to the corner tip. The texture is hard and the taste is light.

Common counterfeit products include long-tailed yellow sheep horns, Tibetan antelope horns, and yellow sheep horns. The shapes of the three fake products are all flat, unarched or straight. The color may be black, dark brown, or light brown, all opaque. The raised ring ridges may be few or irregular, and the distance between the ring ridges is generally small.
