Minecraft Worldbuilding - Medicinal uses that aren't potions
There is one obvious healer in Minecraft; a potion of regeneration. A potion of healing works, too. But these aren't always easy to get, as you'd need to go to the nether for the ingredients.
A pufferfish is commonly used for a painkiller replacement in seaside locations. In large doses it makes you feel sick, yes. But if you carefully extract the viscera and dissolve it in water, it has a numbing effect. This has to be done with extreme caution and care. Add just a little more of the poison to your solution, and you might end up poisoning an already sick individual.
Still in seaside or Riverside locations, squid and squid ink are often consumed due to its level of antioxidants. Squid ink pasta is a popular food to give to the sick, same with kelp soup.
Prismarine is hard to get by; you'd have to go to a sea temple for it! But if you have some, it has incredible uses for treating burn wounds, especially second or third degree burns. It is ground up to a fine powder and then mixed with water, it's applied as a cream when needed. Due to its special use and rarity, it's usually only used for those with more wealth.
