How to identify the antler?

The velvet antler's identification product has many antler traits, and the quality of the antler varies greatly. It is generally distinguished from the aspects of color, texture, odor, etc. The shape of pilchard antler is usually He-shaped or oval-shaped, with a diameter of 1 to 4 cm and a very thin slice. The skin is red-brown. Sawing mouth surface is yellow-white to brown-yellow, with an obvious ring-shaped bone or no, darker color in the periphery, with honeycomb-like pores in the mask, gradually widening or being hollow in the middle, and some appear brown. Lightweight, hard and brittle. Slight gas, taste salty.

In general, pilose antler tablets are light, cross-section honeycomb, compact organizations are superior products. The ancients accumulated rich experience in identifying pilose antler. For example, in the book “Identification of Novel Drugs”, the book contains: "The top of the velvet, the first layer of white, such as wax, oil, such as fat, the name of the wolfberry wax; sub-white and yellow, pure blood infusion Among them, the name of the scorpion blood film; the most sub-layer piece of honeycomb, purple and black through holes, the name of the wind bleb, common cloud wood film, such as the wood through the air pass also. The most time the bone adjacent, similar to the same angle The name of 曰 曰 曰 曰 , , , , , , , , 效力 " " " " " " " " " " " ". In the modern medicine market, the antler is often sliced ​​and cut near the top, called "blood pieces." The blood piece is about 1 mm thick, which is honey-colored, slightly reddish, and smooth on one side. We say "powder" called cut in lower velvet. The powder is about 1.5 mm thick, grayish white, floury, one-sided light, fine pores, dark purple skin, and hernia. The "sand piece" is near the bone end and has a rough surface with cellular pores. Blood tablets are very effective, expensive, followed by powder and cheaper prices, followed by sand tablets. The "bone piece" is the most recent bone, and the quality is worse than that of the sand piece.

Modern pharmacists found that the top extract of antler has the highest biological activity, and the superficial antler cells of pilose antler are more infertile as they approach the top, and they have large and long spindle-shaped cells on the top of the pith. The antler's base has the lowest biological activity, and the chemical composition and content in the middle can basically represent the average value of the whole antler.
