According to traditional oriental medicine, only non-coagulated native deer blood is said to be effective, and coagulated deer blood is ineffective. Thus, a drying and tablet-producing method for deer blood was developed to maintain its physiological and therapeutic activity, and so that after drying, it can be redissolved and protected from coagulation. Proteases such as trypsin, pepsin, chymotrypsin, and aminopeptidase were added to the deer blood indicating that it coagulated in an hour, as shown by the reference. Wax gourd extract, which is high in protease, was added to the blood resulting in anticoagulation for 31 hours. Also, additions of 1% EDTA, 0.38% sodium citrate, 0.16% calcium oxalate, 1.2% ethanol, and 0.006% heparin to the deer blood resulted in anticoagulation for 1 hour, 4 hours, 2 hours, 1 hour, and 31 hours, respectively. In an experiment using 0.19% sodium citrate plus 1% wax gourd extract, and 0.006% heparin plus 1% wax gourd extract, anticoagulation was maintained for up to 72 hours. However, since heparin can not be used in food, the deer blood tablet was made with the addition of 0.19% sodium citrate and 1% wax gourd extract, followed by freeze drying. The dissolution rate for the tablet manufactured in this manner was 96.7%. And the dissolution rates for spray-dried deer blood, vacuum-dried deer blood, and marketed deer blood tablets were 85%, 81%, and 25.5%, respectively. The composition of the tablet produced from the freeze-dried deer blood was 56.4% protein, 18.7% lactose, 1.2% amino acids, 1.0% glucose, 0.7% lipids, 180 mg/100 g of iron, 13 mg/100 g of potassium, 39.1 mg/100 g of calcium, 480 mg/100 g of sodium, 368 mg/100 g of chloride, each.
