Covid . alternative cures?

I’ve heard that there are scams offering a cure for COVID but are there any ‘alternative’ cures that might help reduce our chances of catching it?

I have heard that pineapples - leaves boiled for an hour and drinking the liquid, or eating any part of them including the core, is a remedy used in many tropical countries to reduce fever and inflammation and is being used by people for Covid as well. ( Bromelain tablets have the same active ingredient).
I also know someone using a homeopathic remedy that she says is widely used in India - again three well known anti inflammatory remedies.
I know that any good diet would help but find it hard to stay away from chocolate!
