Do you think that anyone can just test things on humans without going through the government first? That is highly illegal. That is not easy or cheap to do. The drug companies aren't going to do it, or allow it, since they are very entwined with the FDA. It threatens their business model and no profit is involved for any drug company.
Naturopathic doctors are only legally able to help you because they are technically just giving you the idea you try it yourself, and the law can't limit free speech. They legally cannot prescribe a medical course of treatment or run experiments on people.
The fact that people are claiming to have their cancers cured with such things as garlic, that we read about Hippocrates curing people with garlic, a testimonial of people having their cancers cured when following Hippocrate's therapies, that we see studies showing that cancers have been reversed in animals, and databases with thousands of studies showing anti-cancer effects, is all cumulative evidence. You are increasingly needing to provide more evidence that it is all illegitimate.
He is an article that dispels the myth of Hippocrates are the source of all the acts and writings that we attribute to him.

In fact it is widely accepted that Hippocrates did not write the oath, no text in the hippocratic corpus can definitely be attributed to him and it is more likely that these texts were assembled over a few centuries by various people. Some historians have identified as many as 19 authors involved in the Hippocratic corpus. So... you can kindly refrain from pushing your argument from authority, thanks.
What kind of diversion is this? Where did anyone say that Hippocrates wrote the Hippocratic Oath? Pointing out someone's misconception does not prove that Hippocrates was a fraud, or that he never treated people with cancer.
If I swear an oath to God, does it imply that God wrote that oath? Ridiculous diversion.
Per your mention of the hippocratic corpus, it says right on the Wikipedia page that it is authored by a bunch of different people who liked Hippocrates. Who is attributing it to Hippocrates?
https://en.wikipedia.org/wiki/Hippocratic_OathThe original oath was written in Ionic Greek, between the fifth and third centuries BC.[1] Although it is traditionally attributed to the Greek doctor Hippocrates and it is usually included in the Hippocratic Corpus, most modern scholars do not regard it as having been written by Hippocrates himself.
Clearly, if there was oath to someone's philosophy, in this case the Hippocratic philosophy, it does not imply that the person who originated that philosophy created that oath.
