Over high heat in a large stockpot, bring water to a boil.
Add soup bones, shank bones, salt, garlic, and onion and boil for about 10 minutes. Lower heat to low, cover pot, and simmer for about 2 1⁄2 to 3 hours or until meat on bones is tender. Skim excess foam off the top as it forms and discard.
Add cabbage, carrots, celery, potatoes, zucchini, tomatoes, corn, tomato sauce, safflower petals, coriander seeds, and cilantro. Let it all cook for about 30 minutes, until potatoes are soft but not mushy.
Prepared soup can be frozen for up to three months.
Anytime you prepare a soup recipe with tougher cuts of meat, you could cook the meat in a crockpot overnight or pressure cooker/Instant Pot (cover with plenty of water). Then, finish it on the stove top.
