This product is the skeleton fossil of ancient mammals such as elephants, rhinoceroses, cattle, three-toed horses, etc., or the fossils of elephant incisors. The former is commonly called "Fossil Bone", and the latter is commonly called "drgon's bone". Mainly produced in Shanxi, Inner Mongolia, Shaanxi, Gansu, Hebei and other provinces. It can be mined all year round. Because it is easily broken when exposed to the air after being unearthed, the soil and other impurities should be removed immediately when digging, and then pasted with rough paper.

drgon's bone is also called green Fossil Bone and flower Fossil Bone. It is in the shape of irregular blocks or cylinders or semi-cylinders, with different sizes. It is generally light gray-white, light yellow-white or light yellow-brown, with blue-gray and red-brown patterns, varying in depth and thickness. The surface is smooth, with small cracks from time to time. It is hard and brittle, easily peels off in flakes, has a reticulated cross-section, and is highly hygroscopic. It has suction when licked with the tongue. Odorless and tasteless. The ones that are crispy, layered, have Wuse patterns and have strong moisture absorption capabilities are better.

Fossil Bone is also known as white Fossil Bone. The main difference from drgon's bone is that it is skeletal or broken into irregular blocks, without patterns, but some have textures, cracks or brown stripes and spots; it is hard and not easily broken, and there are no flakes falling off, the cross section is flat, and there are Honeycomb-like pores seen in joints are generally considered to be of lower quality than drgon's bone. The ones with hard texture, white color and strong hygroscopicity are better.

[Modern Pharmacology]

Mainly contains calcium carbonate, calcium phosphate, a small amount of iron, magnesium, aluminum, potassium, sodium, chlorine, sulfate, etc.

Blood calcium accounts for only 0.1% of human body calcium, but it has a great impact on nerves, myocardium, bones and other tissues. When blood calcium content decreases, neuromuscular stress increases, causing convulsion, convulsions, delirium, etc. in the hands and feet; excessive blood calcium causes neurological symptoms or muscle weakness. After calcium enters the blood, it can promote blood coagulation and increase the density of the blood vessel wall to prevent white blood cells and serum from leaking out of the blood vessels. At the same time, it can reduce the excitability of skeletal muscles. Therefore, Fossil Bone has sedative, astringent, astringent, and antidiarrheal effects. In addition, calcium deficiency is associated with the development of intestinal cancer. Research results also show that severe calcium deficiency not only affects bone calcification, but can also cause bleeding and paralysis, starting with paralysis of the lower limbs.
