What are the effects of yellow gelatin

Yellow gelatin is a colloid made from yellow cow hide and is widely used in traditional Chinese medicine. Due to the special raw materials used to make yellow gelatin, yellow gelatin is particularly rare, so it is used with great care. Yellow gelatin is a kind of medicine that has the effects of nourishing yin and moistening dryness, stopping bleeding and reducing swelling. It has a good effect on bruises and sprains. So, what other benefits does yellow gelatin have?

[Synonyms] Water glue (Wai Tai), cowhide glue (Bencao Tujing), sea rhinoceros glue (Compendium of Materia Medica), Guang glue, gelatin (Ben Jing Feng Yuan).

[Source] It is a glue made from the skin of cattle. The original animal is detailed in the entry for "beef".

[Preparation method] Chop the dried cowhide into small cubes and soak them in clean water for 2 days. Stir and change the water frequently until the cowhide becomes soft, then wash and take out. Pour it into a copper pot, add about 5 times the amount of clean water, heat it to make it boil slowly, and add water at any time, filter out the clear liquid every 24 hours, repeat this 3 times, precipitate all the filtrate with alum, pour out the clear juice, heat it into the copper pot again and concentrate it until it does not dissolve when dripped on the filter paper, add auxiliary materials such as rice wine or rock sugar to collect the glue, pour it into a glue tray, wait until it cools, cut into small pieces, and dry it.

[Chemical composition] When yellow cow hide is boiled with water for a long time, the collagen in the hide changes into yellow gelatin. The collagen in cowhide contains 18.6% nitrogen and some sugar. The total amount of 100,000 grams contains the following amino acid molecules: glycine 863, alanine 107, valine 20, leucine + isoleucine 43, proline 131, hydroxyproline 107, phenylalanine 15, tyrosine 5, serine 32, threonine 19, methionine 5, arginine 49, histidine 5, lysine 31, hydroxylysine 7, aspartic acid 47, and glutamic acid 77. After changing to yellow gelatin, the nitrogen content is 18.0%. The number of amino acid molecules in 100,000 grams is: glycine 359, alanine 105, valine 28, leucine 28, isoleucine 14, proline 129, hydroxyproline 111, phenylalanine 15, tyrosine 6, serine 30, threonine 19, methionine 6, arginine 49, histidine 5, lysine 32, hydroxylysine 7, aspartic acid 51, glutamic acid 76. Compared with the above, it can be seen that the composition of collagen and gelatin has also changed slightly, but the fact that both of them do not contain cystine and cysteine ​​is their characteristic: the significant difference in properties is that collagen is insoluble in water, while gelatin is soluble in water. Gelatin also contains a small amount of calcium, which is mainly added during the degreasing process with lime.
