Velvet antler is the tender horn of stag, which is a kind of medicinal material containing a variety of colloidal substances, calcium with different structures and a variety of complex and trace rare ingredients. Because the source is not abundant and the price is expensive, the original material should be swallowed as much as possible when it is used, and it should never be used as a decoction. If it is used as a decoction, its gelatinous substance will stick to the dregs of other drugs and be wasted, or stick to the height of the inner wall of the medicine pot and be baked into waste or even become a coke that is harmful to health. Therefore, in the past dynasties, doctors used velvet to grind it into fine powder and swallow it directly or mix it with other powder to make pills for taking. For example, the pilose antler powder for the treatment of rickets and other debilitating diseases in Qian Jin Fang is made by grinding pilose antler, angelica sinensis, donkey-hide gelatin, cuttlefish bone and other medicines into powder, directly taking it with light salt water or mixing it into paste and swallowing it. The Bushen Dihuang Pill used to treat children's "congenital five soft diseases" in Yi Zong Jin Jian is based on Liuwei Dihuang Pill, with pilose antler and Achyranthes bidentata added, ground into fine powder and refined with honey. These two prescriptions have been used by modern people to treat severe rickets, hyperosteogeny, myasthenia gravis and sexual dysfunction. In the prevention and treatment of osteoporosis, these two aspects can be used as the basis and adjusted according to the specific situation. Some people who like to drink wine will enjoy velvet antler as a tonic. Although this is a simple method, the dosage is not easy to control, and the ethanol in the wine will affect the absorption and utilization of calcium by the human body, so it is not ideal. When people use pilose antler as a tonic, it is often still the traditional method of eating ginseng: carefully choose the winter solstice and stew it with lean meat. If this method is used to enhance sexual function, or to treat sub-health symptoms such as soreness of waist and knees, dizziness due to blood deficiency, fatigue and so on, or to treat intractable insomnia after recovery from acute and severe diseases, or to treat neurasthenia, or even to treat intractable diseases such as gastric ulcer or chronic carbuncle, it is suitable to stew antler with meat for surprise treatment. However, if it is used to prevent and treat "static diseases" such as osteoporosis, it will be too troublesome and difficult to work. Besides, pilose antler is different from red ginseng, which can improve the absorption and utilization of thermogenic nutrients, and can improve the cold resistance after taking it in moderation, so taking it before winter has more benefits than taking it in other seasons. Pilose antler without this effect can be taken in winter and any season. The best way to use antler for tonifying kidney and strengthening bones for osteoporosis and other similar chronic diseases is to take 1 ~ 2 pieces of antler and put them directly into your mouth, let saliva dissolve slowly, slowly swallow the saliva with antler dissolved, and finally chew the residue and swallow it. This is much more convenient than grinding powder to swallow, and the absorption rate of effective components is higher and the dosage is less, and the quality of the used velvet chips can be identified from it. When the sliced velvet is used for stewing, the dosage is 1 ~ 4g each time (about 3 cents to 1 yuan and 2 cents); However, the dosage of directly containing rongrong tablets is / only two paragraphs are found in the poems about deer: (Tang) Qin Renyao, an ancient wonder: the upper and lower parts are covered with each other, and the red deer is upside down.
