There isn’t any fruit that can “heal eyesight” or “regenerate the liver and kidneys.” Those claims are not supported by medical science. Eyes, liver, and kidneys can be affected by nutrition and disease, but no fruit can repair or regenerate them in that way.
That said, there are fruits with extremely high vitamin C—much higher than oranges:
- Kakadu plum (Australia) is one of the richest known sources, with up to ~50–100 times more vitamin C than oranges depending on conditions.
- Acerola cherry can have about 20–30 times more vitamin C than oranges.
- Guava also has significantly more vitamin C than oranges.
Vitamin C helps with:
- Supporting the immune system
- Collagen production (skin, blood vessels, connective tissue)
- Helping the body absorb iron
But it does not:
- Restore eyesight once damaged (though it supports general eye health alongside other nutrients like vitamin A and lutein)
- Regenerate organs like the liver or kidneys
- Cure diseases on its own
The liver can repair itself to a degree naturally, but that depends on the cause of damage (like alcohol, infection, or fatty liver disease) and medical treatment—not a specific fruit.
If you want, tell me what claim you heard or where you saw it, and I can break it down more specifically.
