Yes, it's called clinical trials. That's how new and important, not to mention more affordable, and faster cures for debilitating conditions are proven effective. Thats why there are often several medications available for any given ailment. New discoveries are made all the time.
Say you have cancer. If a doctor told you you could go through months of Chemo-therapy, or take a new pill to cure cancer, which would you choose? You're gonna die if you don't try one of them.
So is it the one where all your hair falls out, makes you puke, ruins your appetite, and could kill you anyway, since it's a proven method?
Or do you try a new pill that allows you to have a good quality of life, not put your body through so much stress, and works, but without a long track record of years of success?
The choice is yours as well Mr Science Guy. I see this "unproven" ginger treatment as a better alternative. Chemotherapy and hyposalinity do not have a 100% success rate BTW. 
But hey, what do I know? I'm just a lowly hobbyist.
A clinical trial would never be started before it has already been demonstrated that the treatment actually does something. This would involve various
in vitro studies on tissue samples and then trials on mice or rats again to see if the treatment does something.
The clinical trials, once started, are very closely monitored with tests being done on the patients before, during and after the treatment to assess the affect of the treatment both on the ailment and on the general health of the patient. Additionally, the clinical trial would include some patients who are given a placebo to eliminate psychological effects. Finally, many clinical trials are terminated early because of side effects of the drug being tested.
People trying ginger when they think their fish have
Cryptocaryon is so far from a clinical trial it is not funny. Apart from the fact that absolutely no prework has been done to show that ginger does anything for the fish or the parasite, there is no verification before, during or after the treatment on the status of the
Cryptocaryon. There is no control group receiving the placebo. There is no assessment of possible side effects of the treatment on the fish or other organisms in the tank.
At this point all we have on ginger is a very small number of people that tried it and found that the fish recovered from a suspected
Cryptocaryon infection. It is worth noting that fish can and do recover from
Cryptocaryon without any treatment at all through an acquired immunity.
For the cases where ginger has apparently been successful:
* We do know that the fish had
Cryptocaryon
* We do no know if they recovered because of the ginger or because of an acquired immunity
* We can't even be sure that the
Cryptocaryon has gone. Perhaps ginger causes a partial immunity
* We do not know if ginger has any side effects to the fish or any other organisms in the tank
* We don't even know that ginger does anything
I don't understand how you can claim that ginger is a "better alternative" when we don't even know if it works.
