Vinegar and Lycium barbarum can cook bone soup together. Lycium barbarum bone soup is the most commonly used stew, which is very nutritious and healthy. Adding some vinegar in the boiling process of bone soup can dissolve inorganic calcium salt into calcium acetate, thus increasing the content of calcium ions in bone soup, making bone soup more nutritious, easier to be absorbed by human body and beneficial to health. After the water is boiled, vinegar can be properly added, because vinegar can dissolve phosphorus and calcium in bones into soup, which is beneficial to supplementing calcium, softening blood vessels and lowering blood pressure.

I hope this helps.
